Is Your Cold Lime Softener Effective?
Loraine Huchler
If your plant's utility system is experiencing problems, the culprit may be the clarifier. Understanding how to diagnose and correct off-spec clarifier operation will allow downstream units to function more efficiently and reliably.
Addendum to Realistically Predict Capacity and Pressure Drop for Packed Columns -- Original Paper as presented at the 2007 Spring National Meeting
GPDC Interpolation: Use, Misuse and Updates
Discussing Climate-Change Challenges
Matthew McKeon-Slattery
The U.S. is still at odds with other developed nations when it comes to a strategy for reducing greenhouse gas emissions. At the G8 Summit, President Bush opposed a pact advocated by German Chancellor Angela Merkel calling for CO2 emissions to be...
Efficient Technology Evaluation
Francesco Citro, Reuel Shinnar
To stay competitive in today's economic climate, rapid and effective assessments of new technologies is a must. Requiring a minimal amount of data, this powerful method can effectively evaluate new ideas and research programs at an early stage...
Understand the Emerging Issue of Vapor Intrusion
Matthew Traister
The migration of vapors from contaminated groundwater and soil into aboveground buildings can adversely affect indoor air quality by creating an exposure pathway that may not have been addressed previously.
Mitigating Global Climate Change Through Power-Generation Technology
Frank Princiotta
With the Intergovernmental Panel on Climate Change set to release its Fourth Assessment Synthesis Report later this month, now is a good time for chemical engineers to take a look at this topic. This article provides a succinct integration of...

Tools to Model Multiphase Separation
David Connolly, Saeid Mokhatab, Timothy Newton
The flow fields in multiphase separators are often extremely complicated, making it difficult to model such systems. Computational fluid dynamics (CFD) and visual dynamic modeling (VDM) can be used together to overcome some of the challenges.
Properly Select Equipment for SIP Systems
Tony George
Sterilization-in-place (SIP) systems are essential to the operation of many pharmaceutical and biotech facilities. This article reviews design considerations, selection criteria and performance expectations for control valves, regulators, isolation...
Improving Heat Exchanger Designs
Christopher A. Bennett, David C. King, R. Stanley Kistler, Thomas G. Lestina
This article defines and explains the factors that affect heat exchanger design margins. With the proper application of design margins, capital costs can be lowered and plant operations improved.
Scaling Fixed-Bed Catalyzed Processes
Jonathan H. Worstell
The new parameter introduced here will yield more meaningful results when a fixed-bed reactor is scaled up for process development or scaled down for plant support.
