Take a Hands-on Approach to Refinery Troubleshooting
Dana Laird
The solution to a process problem isn't found by sitting behind your desk, but by going into the plant and carrying out tests and evaluating data.
Ease Control Valve Selection
Kiran Nair, Liyakat Jaffer, Meredith Chapeaux, Sheetal Patel, Trevor Bishop
With so many types and options available, choosing the right control valve can seem daunting. Selection can be simplified by considering the process fluid, the service requirements, how the various valves function, and seeing how each valve will...
Innovations in Food Processing
B. G. Swanson, G. V. Barbosa-Cánovas, M. F. San Martín
Today's savvy consumers want processed foods to look freshly prepared, while still meeting all safety requirements. Conventional thermal treatments are inadequate to fulfill this demand. New nonthermal techniques, such as pulsed-electric fields, are...
Reduce Dust Explosions the Inherently Safer Way
A. G. Dastidar, Faisal I. Khan, P. R. Amyotte
This article is aimed at the development of a framework for dust explosion prevention and mitigation that explicitly incorporates the principles of inherent safety. As distinguished from engineered and procedural safety features, inherent safety...
Improving Slurry Viscosity and Flow-Curve Measurements
Neil J. Alderman
Use these techniques to ensure a slurry's rheological properties have been evaluated under relevant test conditions, and that measurements are accurate.
From Bench to Plant: Scale Up Specialty Chemical Processes Directly
Ron Leng
Many batch operations can be scaled up directly from the bench to the plant by developing the process and performing lab testing with the scaleup in mind.
Prevent Caking During Solids Handling
Brian H. Pittenger, Gabriel I. Tardos , Herman Purutyan
Use these guidelines to avoid potential caking problems. The key steps are to select a material characterization method, identify the factors that can be feasibly controlled and conduct tests to confirm that process/handling changes yield the...
Maximize the Performance of Your Spray Nozzle System
Christine Pagcatipunan, Rudi Schick
Use these techniques to select, troubleshoot and maintain spray nozzles for optimal results.
Rapid Process Design
Michael Doherty, Sagar B. Gadewar
Use this structured approach, which combines preliminary experimental data with predictive methods and heuristics, to quickly generate and screen process alternatives at the early stages of a new venture.
Dividing-Wall Columns Find Greater Appeal
Gerald Parkinson
Conceived more than seven decades ago, dividing-wall columns are now only gaining widespread acceptance. The reasons— the drive to save energy and advances in computer technology that have overcome the burden of doing complex column internal designs.
Piloting Bioreactors for Agitation Scale-Up
Gregory T. Benz
This article offers guidance on how to design appropriate experiments to measure scalable data for agitation in both aerobic and anaerobic bioreactors.
Form Nanoparticles via Controlled Crystallization
Robert J. Fisher, Thomai Panagiotou
This continuous bottom-up approach allows precise control of the crystallization process to achieve size, distribution and quality goals, as well as realize the benefits of process intensification.
Obtain the Best Physical Property Data
Kevin G. Joback
Physical property values are essential for many chemical engineering tasks. This article reviews sources of physical property data, discusses the use of experimental methods to measure properties, and details several types of estimation techniques.
Save Energy Through Automation
Douglas C. White
