Chemical Engineering Progress (CEP) is AIChE's flagship publication.  This monthly magazine provides essential technical and professional information to practicing chemical engineers through their membership in AIChE.  SBE members receive the bi-annual BioSupplement, a special section to CEP that explores topics of interest to our members.  The most recent issue on was published in July 2011 and includes articles:

Don't Let Baffle Tray Flood Baffle You

By Henry Z. Kister and Matthew Olsson
Use this new correlation based on window liquid velocity to predict baffle tray capacity.

Reduce Piloting Time and Cost

By David A. Berg and Michael T. Cleary
Pilot-scale experimentation is essential to establish a sound foundation for a new chemical processing unit. These best practices can reduce the time and cost involved in process development. 

Developing Screening Cost Estimates

By Richard P. Palluzi, P.E.
Making decisions based on estimates derived from weak data is counterproductive. Use this established methodology to prepare scoping and screening cost estimates for pilot plants quickly and accurately.
