Selecting Membrance Filtration Systems. Chen, W.; Parma, F.; Patkar, A.; Elkin, A.; Sen, S. Chemical Engineering Progress December 2004, 22-25.
Practical guidelines for choosing from available membrane materials, pore sizes and module configurations.
Understanding Flow Patterns in Glass-Lined Reactors. Dickey, D.S.; Bittorf, K.J.; Ramsey, C.J.; Johnson, K.E. Chemical Engineering Progress November 2004, 22-25.
Combining CFD simulation with actual models reveal flow patterns in glass lined vessels with a retreat curve impeller and single glass-lined finger baffle. The lack of significant effect of the baffle and the applicability of the physical model when modifications need investigating are the main conclusions.

Separation Characteristics of Swirl-Tube Dust Separators. Peng, Hoffmann and Dries. AIChE J. 50, 87-96 (2004).
The performance of a simple cylindrical "swirl-tube" dust separator was compared to a tangential inlet cyclone and found to be comparable in pressure drop, grade efficiency curves and overall efficiency. Using the scaling rules and simple models, the swirl-tube is the more compact of the two designs when operated at similar values of the performance parameters.
