Chemical Online / Pharmaceutical Online Column

I have also written a number of columns on technology issues in Chemical Online and/or Pharmaceutical Online. A list of the past columns on this subject are:

Draining Time for Unpumped Tanks

Calculating gravity-powered flows can be tricky because the head changes with time and vessel shape. Chemical Engineering June 2000, pp. 115-119.

Manufacturing - The Next Frontier for Biotechnology

By tapping into the knowledge avaliable in the chemical process industries, biotech companies can profit from the high potential of their industry. View point BioPharm September 1993.

Optimize Cycle Times for Batch Biokill Systems

Outlines the design and optimization of batch bioinactivation systems normally present in facilities using fermentors and/or bioreactors to produce their products. Chemical Engineering Progress October 1994.

Think Small

One way to minimize new plants' required size is to convert more aspects of pharmaceutical processes from batch to continuous systems, Pharmaceutical Manufacturing, Fall 2002.
