Consider the Equipment Implications of Bioprocessing
By Bill Newton, Flowserve
Biotechnology is assuming an increasing role for producing chemicals. The nature of bioprocessing differs from conventional processing, so the choice of equipment such as pumps and valves must factor in the differences.

Get the Most From Your Flexible Screw Conveyor
By Mike Zeluff, Hapman
Many end-users overlook important factors that can lead to poor performance, excessive power usage, severe wear and material degradation. It's essential to consider all system parameters when deciding among conveyor options.
Instrumentation and Control
Get Accurate pH Measurements
By Frederick Kohlman, Endress+Hauser
Installing two pH sensors may seem a sensible way to achieve accurate readings — but in practice isn't a reliable approach. Using three sensors instead can improve the accuracy, dependability and believability of readings.

Put V-cone Flow Meters on Your Short List
By Andrew Sloley, Troubleshooting Columnist
Sometimes, even with flow conditioners, the amount of straight pipe run available isn't enough to ensure the accuracy of an orifice flow meter. The V-cone meter only requires a short straight run and so may be a good alternative.
Energy Saver
Refinery Improves Boiler Feed Water Quality
By Ven Venkatesan, Energy Columnist
By replacing its hot lime softener with a reverse osmosis unit, a refinery successfully enhanced its boiler feed water quality while saving energy. Many other chemical processing plants may benefit from adopting this approach.
