Before Submitting – Preparing and Formatting Documents

Types of Publications

The Canadian Journal of Chemical Engineering (Can. J. Chem. Eng.) publishes original research articles, new theoretical interpretation or experimental findings, and critical reviews in the science or industrial practice of chemical and biochemical processes. Preference is given to papers having a clearly indicated scope and applicability in any of the following areas: fluid mechanics, heat and mass transfer, multiphase flows, separations processes, thermodynamics, process systems engineering, reactors and reaction kinetics, catalysis, interfacial phenomena, electrochemical phenomena, bioengineering, minerals processing and natural products, and environmental and energy engineering. Papers that merely describe or present a conventional or routine analysis (without novel elements) of existing processes will not be considered.

  1. Article — a full-length paper describing a new theory, or significant and substantial new results in any of the areas identified above.
  2. Letters — two types:
    1. from authors, correcting or briefly elaborating on a paper previously published in the Journal;
    2. from others, commenting on material previously published in The Canadian Journal of Chemical Engineering. Normally, these will be sent to the authors of the prior publication for their response before publication.
  3. Note — describes the results of a short but complete study, or describes new or significantly improved experimental methods or devices.
  4. Review article — normally by invitation. Authors wishing to submit a critical review should consult the Editor-in-Chief, in advance.
  5. Special Issue article — by invitation only.
  6. Special Series article — organized and invited by guest editors in different areas of expertise.
  7. Award Paper — by invitation only.

Submission of a paper implies that it is not being considered for publication elsewhere and that it has not been published previously in any archival publication. All the co-authors should have approved the submission, in advance. Articles, notes, review articles, special issue articles, and special series articles will be reviewed by up to three persons knowledgeable of the topic. Reviewers will remain anonymous.

Instructions to Authors

All authors should read the Canadian Society for Chemical Engineering Publication Ethics document. Authors are encouraged to read Writing a Scientific Paper: From Clutter to Clarity by Gregory S. Patience et al.

Manuscript Requirements

The manuscript must be in either English or French, and use Canadian spelling. It should have been carefully checked for clarity, conciseness, correctness of grammar and spelling, and typographical errors. The manuscript and all figures and tables must be supplied in electronic format. Please note that Can. J. Chem. Eng. follows the International System of Units (SI) and the Chicago Manual of Style (16th edition), excepting only reference style and Canadian spelling standards. For Canadian spellings, consult the Canadian Oxford Dictionary. Standard formal academic language is required; e.g. contractions (“can’t, don’t, wasn’t”), slang, and other casual language are not permitted.

All articles should be submitted in 12 pt Times New Roman font in a single column with 2.5 cm margins. The abstract should be single spaced and the main text should be in 1.5 spacing. Figures and tables should be embedded in the .doc(x) (Microsoft Word) file for the initial submission.

Title Page

Author names

Every author’s name must include at least one full (non-initialized) given name.

Affiliation address format

Name of institute, (parent institute if applicable,) city, province/state/region, (optional postal code,) country

Example: The Canadian Journal of Chemical Engineering, Chemical Engineering Society of Canada, Ottawa, ON, Canada

Corresponding author

Indicate the corresponding author with an asterisk (*), and provide their email address or other preferred contact information in a footnote on the title page.

Abstract and keywords

The abstract is to indicate in no more than 250 words (maximum of 2 paragraphs) the scope and principal findings of the work (abstracts are not required for letters). Following the abstract, provide a maximum of 5 keywords or key-phrases (10 words total). Avoid general and plural terms and multiple concepts (avoid, for example, “and,” “of”). Be sparing with abbreviations. These keywords will be used for indexing purposes.

Example: “combustion, coal combustion, fluidized bed coal combustion, gas fluidization.”

Graphical abstract

Visual summary of the main findings of an article. This type of abstract is optional. This image must be created at larger than 300 dpi at larger than 9 cm wide. A descriptive caption for the graphical abstract is mandatory.

Main Body of Manuscript

Appropriate use of headings and subheadings should be made in the main body. All references, tables, and figures should be referred to in the text.

Headings

Headings must be unnumbered and follow the guidelines below. Any in-text references to the sections must use their titles.

Example: “…see the Introduction section for details.”

1st levelAll capital letters (e.g. MATERIALS AND METHODS)
2nd level  Title case; bold; roman type (e.g. Chemicals and Equipment)
3rd levelSentence case; italics (e.g. Chemicals used)
4th levelSentence case; roman type (e.g. Methane and propane)

Citations

All in-text citations to References sources must be numbered consecutively in the text. They must be enclosed in square brackets and superscripted, and appear after any punctuation.

Examples: “…as shown by Huglin.[6] …According to Jones et al.,[7] …As seen in the literature,[2–6,10,11] …”

Chemical names

Chemical compounds are to be named according to the rules established by IUPAC. Positional prefixes are to be printed in italics.

Example:n-butane, n-C4-H10.”

Equations

All equations should be numbered using Arabic numerals and correctly punctuated. Refer to equations as “Equation (1)” (not Eq. (1) or Equation 1). Standard statistical formulae, such as t-test or ANOVA equations, should be omitted, as these are common knowledge.

Algebraic fractions in numbered equations (including those in Appendices) are to be printed in the following example styles:

Equation 1(1)

Use the oblique slash to indicate division only for simple definitions included in a line of text.

Example: “…where β = cos θ/τ ; dy/dx = (A/x) B.

Numbers and units

Spaces must be included between number and symbol/unit (e.g. “10 kPa”), with the exception of the lone degree symbol (e.g. “90°”). ± and ~ should not have a following space, but should have a space before. =, <, >, ×, and other operators should have a space on both sides.

  • Use the decimal point (.) and not the comma (,) when writing numbers.
  • Numbers with 5 or more digits left or right of the decimal require spaces every 3 digits, counting from the decimal point (e.g. “123 000.142 85”).
  • For all numbers in measurements, equations, or in any technical context, use digits. Do not write out the names of numbers (e.g. “4 g” is correct, not “four grams”).
  • Percentage signs and similar characters should be dropped where possible to ensure readability (e.g. “5 and 10 %” not “5 % and 10 %”).
  • “Larger than,” “smaller than,” or “about/around” in reference to numbers should be replaced with >, <, and ~ symbols where practical.
  • Always abbreviate “minutes,” “micrograms,” etc. to SI symbols when they appear with a definite number. (i.e. only leave them long for e.g. “few minutes”).
  • The multiplication dot, or interpunct (·), is preferred over the cross (×), except in scientific notation (e.g. × 10-3).
  • If possible, use numbers between 0.1 and 1000 with the appropriate multiple in reporting data. Thus 3.1 × 10-8 s = 31 ns. Exception is in a table or figure where the same unit should be used for comparison.

SI units

The Système International d'Unités (SI) must be used for all dimensional quantities. If other quantities are mentioned, give their equivalent in SI units. Consult the BIPM guide for further information. Preferred practice is to use the base units (m, kg, s, K, A, mol, cd) and their derived units (N, Pa, J, W, V, rad, sr, etc.) in the nomenclature and in all equations. However, data may be reported in suitable multiples of these units provided the units are clearly stated.

Note that “weight” and “mass” have different technical meanings, and are not interchangeable. Verify that the correct term is being used in each case.

Where different usages of an SI unit exist, the precise meaning can be specified in the text or in parentheses after the unit.

Example: 100 mV (dc), 15 kPa (gauge), 1000 m3 (STP)

Incorrect: 15 kPag, 1000 stdm3

Complex units

The following requirements apply to units composed of multiple base units (e.g. m/s, W/m2·K).

  • The product of two units should be indicated by a dot ·. Thus m·N = metre newton, mN = millinewton, m·s-1 = metre per second, ms-1 = per millisecond.
  • Division should be shown using one solidus (/): W/m2 · K, but not W/m2/K.
  • At most one prefix should be used, and preferably on a symbol in the numerator (except kg which is a base unit). Thus, V/mm should be kV/m; kJ/g should be MJ/kg.
  • Do not use powers of 10 attached to the units, or variable symbols in tables and figures. Thus D, (cm2/s) × 102 probably means D, mm2/s, but confusion can arise.
  • Do not mix units where avoidable. Thus power consumption per unit volume flow rate should be W·s/m3 = J/m3, not W·min/m3.
Units not permitted

The only non-SI units permitted are those in Table 6 and Table 7 of the BIPM brochure. Units which are not permitted, and the formulae to convert them to accepted units, appear in Table 8 and Table 9. Permitted non-SI units appear in Sections 5.1 through 5.1.4 of the NIST Guide. Please note that for non-SI units, the values of relevant quantities must be given in terms of SI units first, followed by the non-SI units in parentheses.

Example: “0.15 g/g (15 mass%)”

The following are examples of units that are not allowed in The Canadian Journal of Chemical Engineering. For more information, please consult the BIPM guide.

Pressureatm, bar, Torr, psi, mmHg
Amount of substanceg-mole, kg-mole
LengthAngstrom (Å), micron (μ)
Forcedyne, kilogram force (kgf)
Energycalorie, erg, eV
Concentrationnormality (N), molarity (M) (instead use kmol/m3 or mol/L), ppm
Viscositypoise, stokes
Mass, volume, or mole %  wt%, mass%, mol%, vol% (instead use g/g, mol/mol, L/L, or m3/m3 as appropriate)
Permeabilitydarcy

Spelling, grammar, and punctuation

Overall style and grammar

A criterion for publication is that the text is clearly written and understandable. Referring to guide books such as the Chicago Manual of Style, or having a manuscript professionally edited are both recommended.

Canadian spelling

The Canadian Journal of Chemical Engineering requires that submitting authors use Canadian spelling. Below is a list of common words with Canadian spelling (required) on the left and the American or British spelling on the right.

CanadianAmerican or British
analyzeanalyse
behaviourbehavior
centrecenter
fibrefiber
-ization-isation
modelling, modelled  modeling, modeled
mouldmold
sulphur, sulphatesulfur, sulfate
vapourvapor
Punctuation
  1. The Oxford comma is required. This is a comma before the final item in a list of 3 or more items (e.g. “carbon, nitrogen, and helium”). This comma should also be placed in lists where the final conjunction is “or.”
  2. When using quotation marks, keep to the Canadian Press standard, which is to include all punctuation within closing quotation marks (e.g. “the gas showed similar properties.”)
  3. Parentheses: Throughout the text, use only round brackets, “(”, and avoid using square brackets “[” (reserved for citations). When using nested parentheses, only using round brackets is recommended (e.g. “(measurement of volume (v))”).
  4. En dashes (–) indicate ranges between numbers and between subfigures, while hyphens (-) show a relationship between two words. Em dashes (—) create a parenthetical aside, and should only rarely be used.
Formal style
  1. Referential abbreviations: Always use the full words “Figure, Table, Equation” when referring to these items. Abbreviated forms “Fig., Tab., Eq.” are incorrect.
  2. Conjunctions at the beginning of sentences such as And, But, Or, So are overly informal. Instead, transitions such as Therefore, However, Thus, etc. are recommended.
  3. Contractions such as it’s, can’t, wasn’t, etc. should be replaced with the full terms.
  4. Avoid subjective words like good or bad in the text. Instead, use descriptive adjectives to directly explain the situation in quantitative terms.
  5. Informal language: Refrain from using informal or non-standard forms of words (e.g. “till” is an incorrect substitution for “until”).
Equations
  1. Introducing equations: Equations should be introduced with full sentences ending with a colon. Instead of incomplete, ungrammatical sentence fragments such as “this can be seen as:” or “we can find this by:” adding “as follows:” or “the following:” is recommended (e.g. “this can be seen as follows,” “we can find this by the following:”).
  2. When listing the definitions of terms or symbols after an equation, begin with “where” and leave it uncapitalized and unindented (e.g. “where N is Avogadro's number”).
Latin terms
  1. Commonly used Latin words or abbreviations (et al., in situ, i.e., e.g., etc.) are not italicized in text.
  2. “Versus” is always written as a whole word and never reduced to “vs.”

Figures and Tables

Image and table placement is determined during typesetting, therefore “insert table/figure here” notes are unnecessary. Figure and table captions should be listed at the end of the manuscript on a separate page titled “Figure Captions,” or uploaded as a separate document.

Tables

Tables are to be numbered in Arabic numerals and have a brief descriptive title/caption at the top of each table. This title must not end in any punctuation, and should be in sentence case. Column headings should be brief and include the units of the item(s) listed. These units should be enclosed in parentheses (not after a slash or in square brackets).

When citing works in a table, bare citations are not permitted. Authors’ names must be included (e.g. “Smith et al.[6]” is correct; “[6]” alone is incorrect).

Figures

Figures should not duplicate results given in tables. All figures should be numbered with Arabic numerals. Refer to figures as “Figure 1,” not “Fig. 1.” Figure captions must end in a period, and should be limited to basic descriptions of the figures, rather than lengthy interpretations and discussions.

Subfigures should be indicated throughout the text with lowercase letters directly after the figure number and with no spacing (e.g. “Figure 1b”). When citing multiple subfigures from the same figure, the following form is recommended: “Figures 1b–c.”

Image files

Electronic files must be provided for all figures/images, and should be clearly named (e.g. “Figure 1.eps”). Vector based figures (i.e. figures created in Adobe Illustrator) are recommended, and these should be submitted in .eps format. Alternatively, figures can be created in .tif format at larger than 9 cm wide and 300 dpi. Please note that we cannot print your manuscript without clear image files.

Colour figures must be submitted in CMYK. Please do not submit colour figures as RGB.

Please do not submit figures in any of the following formats: JPG, GIF, PSD, CRD, PCT, PDF, BMP, 1-2-3 (or other) Lotus Formats.

Colour illustrations

All colour figures will be reproduced in full colour in the online edition of the Journal at no cost to authors. Authors are requested to pay the cost of reproducing colour figures in print. Authors are encouraged to submit colour illustrations that convey essential scientific information. For best reproduction, bright, clear colours should be used. Place colour images against a white background wherever possible.

Nomenclature

An alphabetical/numerical list of all symbols used in the paper (including symbols used in tables, figures, and appendices) may be provided on separate pages following the main body. Chemical names and units (e.g. “NaCl,” “μm”) should not appear in the Nomenclature, as they are common knowledge.

List Greek letter symbols alphabetically immediately after the list of Roman symbols in a separate subsection entitled “Greek Letters.” Definitions are to be provided for all listed symbols, and SI units are to be listed enclosed in parentheses after the definition, where applicable. List the base units of the symbols, even if other multiples are used in reporting data.

Example

r  density (kg/m3)
T   temperature (°C)
P   pressure (Pa)

References

References to literature must be numbered consecutively in the text. They must be enclosed in square brackets and superscripted, and appear after sentence punctuation. Use of DOI is highly encouraged. Unpublished results and personal communications are not recommended in the Reference list.

Examples: “…as shown by Huglin.[6] … According to Jones et al.,[7] … As seen in the literature,[2–6,10,11]…”

For the “References” section after the main text, please use the following examples as a guide. All examples demonstrate the minimum acceptable information for each reference type.

All authors of a work must be listed, except in rare cases with over 20 authors. Sources which are “submitted” or “accepted” but not yet published, or which do not yet have a DOI, cannot be cited except as a website source.

iThenticate Plagiarism Software

Any article may be screened using this plagiarism prevention software at any stage of submission to ensure the overall similarity index is low. Submissions with a high similarity index may be returned to be rewritten, or rejected.

ScholarOne Submission Process

Step 1

When choosing the “Special Issue Article” designation, clearly state the topic, conference, or event associated with the Special Issue. The guest editor for the Special Issue, who issued invitations, can provide clarification on the topic or event.

Several manuscript types are available:

  1. Article: a full-length paper describing a new theory, or significant and substantial new results in any of the areas identified above.
  2. Letters: two types:
    1. from authors, correcting or briefly elaborating on a paper previously published in the Journal;
    2. from others, commenting on material previously published in The Canadian Journal of Chemical Engineering.
    Normally, these will be sent to the authors of the prior publication for their response before publication.
  3. Note: describes the results of a short but complete study, or describes new or significantly improved experimental methods or devices.
  4. Review article: normally by invitation. Authors wishing to submit a critical review should consult the Editor-in-Chief, in advance.
  5. Special Issue article: by invitation only.
  6. Special Series article: organized and invited by guest editors in different areas of expertise.
  7. Award Paper: by invitation only.

Step 2

A maximum of 10 words is permitted in the keywords. These should match any keywords listed in the manuscript.

Step 3

The initial submission must list the full names of all authors and co-authors.

Step 4

Authors are required to suggest names (with complete mailing addresses) of three or four qualified reviewers for the manuscript, but the selection of the reviewers will be the responsibility of the Editor-in-Chief/Associate Editors. Suggested reviewers must not be at the same institution as any of the authors, to avoid conflict of interest. They must not have read the manuscript before.

Step 5

A cover letter is mandatory. The Corresponding Author should include a Cover Letter to the Editor-in-Chief that provides a short statement about the paper, whom it should primarily interest, and attest that the work is original and not published elsewhere.

Step 6

For initial submission of Word documents, we ask authors to embed figures and tables in the manuscript for ease of reading and review. Carefully following all formatting and submission instructions expedites the review of articles.

If the article is accepted, all figures and tables must be extracted into separate files, in order to undergo typesetting. At this time all highlighting must be removed from the text, and any coloured text changed to black.

A compiled PDF for all LaTeX submissions is mandatory, and can be uploaded as a second “Main Document.”

When text, tables, and figures are uploaded individually, after the review stage, please use the following categories to indicate the type of the file. Text and tables should be saved as DOC (Microsoft Word) or RTF formats.

  1. Manuscript’s Most Relevant Contributions: A file containing the manuscript’s most relevant contributions or research highlights is required upon submitting an article. This file contains a bullet point list of the most important highlights, contributions, or core findings of the article, and should be under 1 page long. Please include 3 to 5 bullet points (85 characters, including spaces, per bullet point is recommended). (MANDATORY)
  2. Main Document: The main content of a manuscript. (MANDATORY)
  3. Figure: An image file that depicts a graph, chart, drawing or photograph.
  4. Table: A table, including its caption and number (e.g. “Table 1”).
  5. Supplementary Files for Review and online publication only: Material which would not be printed in the hard copy but would appear in the online version only, such as extensive data sets or video files.
  6. Additional Files for Review but NOT for publication: Files not intended for publication in any format but that provide valuable background or reference information, that are suitable for peer review.
  7. Additional Files NOT for Review and NOT for publication: Files not intended for publication in any format, but provide valuable background or reference information. These are not suitable for peer review.
  8. TeX/LaTeX Supplementary File: Any file that is part of a TeX/LaTeX document. Note: The main body of the TeX/LaTeX document (i.e. a file ending with “.tex”) should be designated as a Main Document. All files referenced by a main TeX/LaTeX document should be designated as a TeX/LaTeX Suppl File (including other “.tex” files).

TeX/LaTex Submissions

Directory structures should not be used when referencing external files. Upload a PDF version of your manuscript for initial review. Once a manuscript has been accepted for publication, upload the TeX document, all graphics as separate files, any class files, any bibliography files, and the PDF of the final version.

When uploading a LaTeX main document, the system will analyze the file to determine what additional resource files (such as image files and bibliographic files) are necessary to complete the document. For all revisions during the review and publication process, the compiled PDF of the LaTeX file must be provided (“Main Document” is the recommended file designation).

The LaTeX conversion process only allows images to be provided as .eps files.

A ‘Processing Log’ will be provided which constitutes a record of the conversion process. This is to help identify and correct any errors in the LaTeX document. Authors must view the HTML proof of the manuscript, where the link to the LaTeX document will open the PDF proof. This is necessary to ensure all formulas and other special formatting are rendered correctly.

Files uploaded as LaTeX Supplementary Files will not be viewable as individual files in the HTML proof and will not be rendered independently of the entire LaTeX document. Therefore, images and other content will show up in the PDF proof at the location specified in the LaTeX document. In addition, captions for images displayed within a LaTeX proof must be created in the LaTeX document, since image proofs cannot be created separately.

(f) TeX/LaTeX Submissions
• When uploading a TeX/LaTeX main document, the system will analyze the file to determine what additional resource files (such as image files and bibliographic files) are necessary to complete the document.
• The LaTeX conversion process only allows images to be provided as EPS files.
• A ‘Processing Log’ will be provided which constitutes a record of the conversion process. This is to help one to more easily identify and correct any errors in the TeX/LaTeX document.
• Authors must view the HTML proof of the manuscript, where the link to the TeX/LaTeX document will open the PDF proof. This is necessary to ensure all formulas and other special formatting are rendered correctly.
• Files uploaded as TeX/LaTeX Supplementary Files will not be viewable as individual files in the HTML proof and will not be rendered independently of the entire TeX/LaTeX document. Therefore, images and other content will show up in the PDF proof at the location specified in the TeX/LaTeX document. In addition, captions for images displayed within a TeX/LaTeX proof must be created in the TeX/LaTeX document, since image proofs cannot be created separately.


Summary of policy on the use of S.I. units

Reference: Canadian Metric Practice Guide, CAN/CSA-Z234.1-00 (R2011), Canadian Standards Association, 178 Rexdale Blvd., Rexdale, ON, Canada  M9W IR3

Preferred practice is to use the base units (m, s, kg, mol, K, A, cd) and their derived units (N, Pa, J, W, V, rad, sr, etc.) in the nomenclature and in all equations. Data, however, may be reported in suitable multiples of these units provided the units are clearly stated.

The first listed is the base unit; the others are commonly used multiples. Accepted deviations listed in brackets.

Viscosity, kinematicm2/s, mm2/s
Volumem3 , dm3 (=L), cm3

(a) Rules for writing S.I. units
(i) Lower case letters are used throughout except:

  • for the first letter of the abbreviation of a unit named after a person (A for amperes, K for kelvin, Pa for pascals);
  • for the prefixes larger than "kilo," namely, M, G, T, P, E.;
  • for the abbreviation of litre, namely L, to avoid confusion of the lower case (l) with unity;
  • when writing out "degrees Celsius."
(ii) No full stop is used except at the end of a sentence.

(iii) A space is left between the numerical values and the first letter of the units, if any. This includes percentage and degree Celsius

(iv) Units should be used with all numbers, but the unit is spelled out when no number is involved ("3 h" but "a few hours").

(v) Where different usages of an S.I. unit exist, the precise meaning can be specified in the text or in parentheses after the unit. Thus:100 mV(dc),15 kPa(gauge), 1000 m3 (STP), but not 15kPag,1000stdm3.

(b) Rules for writing numbers

(i) The decimal marker should be the points not the comma.

(ii) Write long numbers (>4 digits left and/or right of the decimal point) in groups of three separated by a space, not a comma, beginning from the decimal point. Decimal points in table columns should be vertically aligned.

(iii) The dot must not be used for multiplication of numbers. The cross (×) should be used where absolutely necessary.


(c) S.I. units and their multiples

(i) If possible, use numbers between 0.1 and 1000 with the appropriate multiple in reporting data. Thus 3.1 × 10-8 s = 31 ns. Exception is in a table or figure where the same unit should be used for comparison.

(ii) Do not use powers of 10 attached to the units or variable symbols in tables and figures. Thus D, (cm2 /s) × 102 probably means D, mm2 /s, but confusion can arise.

(iii) In the nomenclature, list the base units of the variables. Thus, use ρ-density, kg/m3, even if other multiples are used in reporting data.

(iv) Do not mix units where avoidable. Thus power consumption per unit volume flow rate should be W·s/m3 = J/m3 , not W·min/m3 .

(v) At most, one prefix should be used and preferably on a symbol in the numerator (except kg which is a base unit). Thus, V/mm should be kV/m; kJ/g should be MJ/kg.


(d) Multiplication and division of units

(i) The product of two units should be indicated by a dot ·. Thus m·N = metre newton, mN = millinewton, m·s-1 = metre per second, ms-1 = per millisecond.

(ii) Division should be shown using one solidus (/). Thus W/(m2·K), but not W/(m2/K).

(iii) A hyphen may be inserted when using a value as an adjective. Thus: 2-h test; 35-mm film.
