Chemical Engineering Practice
Step into the Virtual Plant
Gregory K McMillan, Mark S Sowell III, Michael M Mansy
The ability to warehouse process and control system knowledge offers a vast potential for improved operations by sharing a common source of information and avoiding data duplication.
Squeeze More Out of Complex Columns
Piyush Shah
These distillation setups can cut capital and operating costs by up to 30%, and increase separation efficiency. Here is a straightforward method for evaluation.
Advanced Cubic Equations of State: When and How to Use Them
Chorng H. Twu, Vince Tassone, Wayne Sim
Understanding the strengths and limitations of a cubic equation of state (CEOS) is crucial for selecting the right one for your flowsheet simulation.
Developments in Slurry Handling
Update your knowledge of modeling, optimizing and controlling slurry pipeline flows.
Process Intensification: Has Its Time Finally Come?
Costas Tsouris, Joseph V. Porcelli
Many new technologies are being developed, but several important barriers must be overcome before process intensification is widely adopted.
Does Your Application Call for an F-Shell Heat Exchanger?
Rajiv Mukherjee
If the process has a temperature cross or a low flowrate, an F-shell might prove beneficial.
Selecting a Membrane Filtration System
Frank Parma , Wu Chen
Proper design and scaleup of a membrane filtration system requires an understanding of the availability of membrane material, pore size and module configurations. These practical guidelines will help in the selection process.
Ensure Proper Distribution in Cooling Towers
James L. Willa
Follow these guidelines to achieve thorough mixing of the air and water in the tower.
Designing Suspension-Mixing Systems
Frantisek Rieger, Pavel Ditl
Impeller and vessel geometries are key factors in selecting mixing equipment to efficiently suspend particulate solids in slurries
Understand Temperature Change in Process Stream Mixing
Anil K. Mehrotra, Dharmendra Tiwary
The isobaric and adiabatic mixing of process streams can yield an outlet stream temperature that is either in between, higher than, or lower than the inlet stream temperatures. This article uses simulation to explore temperature-change scenarios in...
Diagnosing Maldistribution in Towers
Simon X. Xu
Gamma CAT-scan technology makes possible the collection of much more vital online process information than conventional diagnostic techniques.
Use Spreadsheets to Estimate Modeling Parameters
Tomas B. Co
Dynamic process modeling based on non-uniformly sampled data and multiple sampling runs, even for nonlinear systems, can be performed using spreadsheet implementations of the weighted-least-squares (WLSQ) and Runge-Kutta WLSQ methods.
A Strategy for Excellence in Process Development
Lionel O'Young, Vaibhav V. Kelkar
Here is how to integrate overall process development activities and identify practices that facilitate commercial process development.
Predictive Modeling in Catalysis - From Dream to Reality
Ana G. Maldonado
In silicocatalyst optimization is the ultimate application of computers in catalysis. This article provides an overview of the basic concepts of predictive modeling and describes how this technique can be used in catalyst and reaction design.
