  1. Effect of Particle Shape on Inline Particle Size Measurement Techniques

    Maryam Mostafavi, Sandra Petersen and Joachim Ulrich

    Article first published online: 2 SEP 2014 | DOI: 10.1002/ceat.201400212

    Powerful sensor technologies to analyze suspension density and mean particle size in crystallization processes inline and in real time are ultrasound, 3D optical reflectance measurement, and focused-beam reflectance measurement techniques. Measurement principles, advantages and disadvantages as well as and the different sensitivities of these techniques with respect to the shape of particles are evaluated and discussed.

    Two-phase flow through a T-junction can cause a major problem of operation and control in oil and gas production due to misdistribution of the phases. Based on previously studied models, the prediction of liquid–liquid two-phase flow at a horizontal dividing T-junction is re-investigated. Attempts are made to predict the split for liquid–liquid systems by including energy minimization.

  3. Design Strategies for Integrated β-Galactosidase Purification Processes

    Ailton C. Lemes, Juliana Ribeiro Machado, Marcela Lazzare Brites, Marco Di Luccio and Susana Juliano Kalil

    Article first published online: 2 SEP 2014 | DOI: 10.1002/ceat.201300433

    As an alternative to the usual primary purification steps, a strategy for β-galactosidase was established from purification methods amenable to scale-up, allowing the application of the enzyme in enzymatic hydrolysis processes. The proposed process design involving aqueous two-phase system, diafiltration, ion exchange, and diafiltration/ultrafiltration led to a high purification factor and recovery of the enzyme.

  4. Mass Transfer Reaction Kinetics of β-Isophorone Oxidation by Air in an Agitator Bubbling Reactor

    Hong Yin, Caiping Sheng, Zhirong Chen, Shenfeng Yuan, Haoran Li and Jun Mei

    Article first published online: 2 SEP 2014 | DOI: 10.1002/ceat.201300726

    Since to date the mass transfer reaction process of β-isophorone (β-IP) oxidation by air has been only rarely reported, the kinetics of this reaction in a lab-scale agitator bubbling reactor is analyzed. A correlation equation of gas phase volumetric mass transfer coefficients is defined, providing a valuable theoretical basis for industrial design of a β-IP oxidation reactor.

  5. Fabrication of Palladium Membranes Supported on a Silicalite-1 Zeolite-Modified Alumina Tube for Hydrogen Separation

    Yu Guo, Hongmei Wu, Lidai Zhou, Zhenbin Zhang, Haiou Liu and Xiongfu Zhang

    Article first published online: 2 SEP 2014 | DOI: 10.1002/ceat.201300830

    Membrane techniques for H2 separation are increasingly demanded in chemical and petrochemical industries. Thin and dense palladium membranes were prepared on macroporous α-alumina tubes by electroless plating using silicalite-1 zeolite as the intermediate and diffusion barrier layer. The excellent hydrogen permeability and stability allow the composite membrane to act as membrane reactor for H2 separation.
