      Fermentation product separation using nanoporous membranes was simulated using computational fluid dynamics. A mass transfer model was developed to describe the porocritical extraction using hollow-fiber membrane contactors. The predicted extraction percentages obtained by the simulations showed very good agreement with experimental values reported in the literature.

      Version of Record online: 3 APR 2013 | DOI: 10.1002/ceat.201200668

      Thumbnail image of graphical abstract

      Microalgae are an interesting source for biodiesel production. The effects of key reaction parameters on the yields of biodiesel and free lutein from Chlorella vulgaris were investigated, including the amount of catalyst, the biomass-to-alcohol ratio, and the reaction time. In addition, a possible process for the separation of the biodiesel and lutein products from the reaction mixture is proposed.

      Version of Record online: 4 APR 2013 | DOI: 10.1002/ceat.201200161

      Thumbnail image of graphical abstract

      The absorption performance of piperazine-containing amine solutions to be used for biogas upgrading was investigated in terms of CO2 capture. The suggested approach was utilized to describe the non-ideality of the absorption isotherms and proved to be suitable also for data reported by other research groups.

    4. An Experimental Study on Binderless Briquetting of Low-Rank Coals (pages 749–756)

      Y. Han, A. Tahmasebi, J. Yu, X. Li and C. Meesri

      Version of Record online: 5 APR 2013 | DOI: 10.1002/ceat.201300067

      Thumbnail image of graphical abstract

      High mechanical strength binderless briquettes using two dried low-rank coals were successfully produced. Drying of low-rank coals prior to briquetting resulted in 30–50 % increase in calorific value. The optimum moisture content for high compressive strength was 12–15 %. The aromaticity of the briquettes was higher than raw coals as a result of decomposition of oxygen functionalities and aliphatic hydrogen groups.

    5. A Method for Flexible Heat Exchanger Network Design under Severe Operation Uncertainty (pages 757–765)

      K. Zheng, H. H. Lou, J. Wang and F. Cheng

      Version of Record online: 4 APR 2013 | DOI: 10.1002/ceat.201200547

      Thumbnail image of graphical abstract

      Since operational flexibility and feasibility of Heat Exchanger Network (HEN) design traditionally are less concerned, an approach for flexible HEN synthesis under severe operation uncertainty is proposed. A case study providing a better solution with less total annual cost and good flexibility proves the potential of this simplified approach.

    6. Development of a Scalable Method for Manufacturing High-Temperature CO2 Capture Sorbents (pages 766–772)

      C. T. Yu and W. C. Chen

      Version of Record online: 4 APR 2013 | DOI: 10.1002/ceat.201200733

      Thumbnail image of graphical abstract

      The main advantages using CaO-based sorbents for high-temperature CO2 capture are their high capacity and advanced CO2 uptake characteristics. A novel process for scalable manufacture of a calcium aluminum carbonate CO2 sorbent is introduced. Using this method, CO2 sorbents with significantly improved performance can be produced in kg-batches.

    7. Conveying Characteristics of Pulverized Coal in a Top-Discharge Blow Tank System (pages 773–780)

      Dense-phase pneumatic conveying of pulverized coal has been widely employed to feed coal to gasifiers. The blow tank is one of the most important instruments in a dense-phase conveying system. The influences of riser inlet height, riser diameter, pulverized coal external moisture content, and supplemental gas flow rate on the conveying characteristics are investigated.

      Thumbnail image of graphical abstract

      The emission of NOx and SO2 into the atmosphere is a major environmental concern because of their detrimental effects. The removal of nitric oxide from flue gas using a homogeneous Photo-Fenton advanced oxidation process was investigated in a lab-scale photochemical reactor in respect to a number of factors, including reaction systems, UV radiation, gas flow, solution temperature and initial solution pH value.

      Thumbnail image of graphical abstract

      Fibrous media exhibit higher filtration efficiencies than other filtration media and important perfor-mance indicators of fibrous media are mainly determined by the internal microstructure. Response surface methodology and numerical simulation were applied to study the influence of structural parameters of the fibrous media on solid volume fraction and pressure drop.

    10. Metathesis of Ethene and Decene to Propene over a WO3/SiO2 Catalyst (pages 795–800)

      Thumbnail image of graphical abstract

      Metathesis between decene and ethene to propene over a WO3/SiO2 catalyst is proposed as a new route for the production of propene. The effects of reaction conditions on the conversion of decene, selectivity to propene, and working lifetime of the catalyst were investigated. An obvious induction period for the metathesis reaction was found.

      Thumbnail image of graphical abstract

      An ultrasonic enhanced salt-containing hydro-distillation (UESHD) method was developed to separate lavender essential oil. The extraction yield of the oil was optimized by statistical software, the separation conditions by the Box-Behnken design. UESHD enabled a more than two-fold yield of essential oil than conventional hydrodistillation.

      Version of Record online: 24 APR 2013 | DOI: 10.1002/ceat.201200275

      Thumbnail image of graphical abstract

      Currently, an accurate dynamic description of multistage bubble column reactors (MBCR) is still difficult. In this study, a mathematical model, based on time-dependent kinetic constants and axial dispersion coeffi-cient in liquid and gas phases, has been developed to simulate the MBCR under dynamic conditions and validated with available experimental data.

      Version of Record online: 24 APR 2013 | DOI: 10.1002/ceat.201200611

      Thumbnail image of graphical abstract

      THF dehydration is a process of economical concern, as the THF demand is increasing. A steady-state design of two-column extractive distillation for tetrahydrofuran-H2O separation is introduced, and optimal conditions are evaluated by minimizing the total annual costs. Both a basic and an improved control strategy are devised.

    15. Computational Fluid Dynamics Modeling of Gas-Liquid Two-Phase Flow around a Spherical Particle (pages 840–850)

      W. Du, D. Feng, J. Xu and W. Wei

      Version of Record online: 24 APR 2013 | DOI: 10.1002/ceat.201200486

      Thumbnail image of graphical abstract

      Gas-liquid two-phase flow around a spherical particle was investigated by computational fluid dynamics methodology. The results show that the film thickness decreases with increasing gas velocity, especially at high pressures, that the flow regime can be changed with increasing contact angle, and that the liquid viscosity, at relatively high values, affects the residence time of the liquid on the particle surface.

    16. Hydrodynamics and Transport Processes during Centrifugal Short-Path Distillation (pages 851–862)

      L.-J. Chen, H.-B. Dong, Q. Li, C.-C. Niu and A.-W. Zeng

      Version of Record online: 24 APR 2013 | DOI: 10.1002/ceat.201200091

      Thumbnail image of graphical abstract

      Up to now, very few works have been reported concerning the interfacial transfer in the short-path distillation process. A computational fluid dynamics (CFD) model based on the volume-of-fluid and species transport methods is proposed for the first time to investigate the characteris-tics of flow and transport processes during centrifugal short-path distillation.
