Matching Your Process Constraints Using Dynamic Simulation

December
2003
Information Technology
Iban Grau, Jose J. Macias-Hernandez, Miquel A. Alos
A rigorous dynamic process simulator can be used to evaluate alternative control strategies for an exothermic reacting process in order to improve its safety and product quality.

Tools to Model Multiphase Separation

June
2007
Fluids and Solids Handling
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.

Track Condenser Performance

Heat Transfer
Brad Buecker
An effective monitoring program can extend equipment life, improve operations, and yield substantial energy savings.

Easily Assess Complex Safety Loops

March
2001
Instrumentation
Lawrence  Beckman
Many safety instrumented systems rely on dissimilar redundant field devices, and this can complicate required analyses. These equations will enable field personnel to handle such situations readily.

Formulating Production Planning Models

January
2004
Information Technology
Jeffrey D. Kelly
Optimize petroleum and petrochemical plant production by understanding the mathematical modeling behind nonlinear planning models.

Optimize Control Room Communications

October
2001
Instrumentation
Brad A. Walker, James E. Lenhart, Karen D. Smith
Faced with more distractions than ever, operators need an environment that is conducive for dealing with abnormal, as well as normal, situations. Effective control room design can help.
