Simulation that includes aqueous modeling can also account for full vapor/liquid/solid equilibria modeling, including redox chemistry.

Uncovering the Realities of Simulation

Computational Methods
Marco S. Satyr
Running sophisticated process simulations does not guarantee correct results. You need to understand the thermodynamic assumptions underlying the program and how to ensure proper applications.

Uncovering the Realities of Simulation, Part 2

Computational Methods
Marco S. Satyro
Simulation software is a commonly used design tool, thanks mainly to its availability on the desktop. However, one has to understand thermodynamic basics before accepting the desktop's final answer.

Understand Temperature Change in Process Stream Mixing

Heat Transfer
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...

Can We Believe the Simulation Results?

Reactions and Separations
Henry Z. Kister
Be careful of these key issues that may generate differences between a distillation-tower simulation and its actual performance. Simulations do not always square with nuts-and-bolts reality.

Correlate Data Effectively

Computational Methods
Faruk Civan
Follow these nine simple rules to avoid common pitfalls and get better results.

Integrate EHS for Better Process Design

Process Development
Lisa Bendixen
Get a jump on process development by addressing environmental, health and safety (EHS) issues together early in the design and development cycle. The result will be a better process and lower costs.

Realizing the Promise of Wireless

Peter Zornio
Innovation drives the growth of wireless technology, as successful applications demonstrate cost savings, reliability, safety, and ease of use.

Validate Your Engineering Software!

Michael  Tanzio
You really can't guarantee that applications work correctly unless you take specific steps to validate the software.
