August
2006
Career Catalyst
Gregory T. Benz
Engineers who specify, scale up or purchase process equipment typically have fewer internal or vendor resources available than in the past. This article explores the problem and offers a solution.

Designing Experiments for the Modern Micro Industries

February
2006
Computational Methods
Phillip H. Williams
Although the sparsity of effects principle is still good advice, we need to be careful of emphasizing it too much -- to the point that it becomes an assumed practice, rather than a useful rule of thumb.

Retrofit Water Systems the SHARPS Way

November
2006
Environmental Management
Sharifah Rafidah Wan Alwi, Zainuddin A. Manan, Norrazi Misran, Mohd Hisham Samingin
Use the Systematic Hierarchical Approach for Resilient Process Screening (SHARPS) technique to quickly and systematically isolate cost-effective and affordable water management options prior to design.

Selecting Corrosion-Resistant Materials

December
2006
Materials
Francesco Picciotti, Marcello Picciotti
This article looks at some common corrosion-resistant alloys and gasket materials that are available for use in applications with high pressures and temperatures.

Understand Temperature Change in Process Stream Mixing

September
2006
Heat Transfer
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...

Optimizing Batch Operations

January
2006
Reactions and Separations
Kah Loong Choong, Robin Smith
Use this novel method to optimize the operating conditions as they vary through time in batch processes.

Use Cascade Analysis to Optimize Water Networks

July
2006
Environmental Management
Dominic Chwan Yee Foo, Zainuddin Abdul Manan, Yin Ling Tan
This numerical technique for identifying fresh water and wastewater targets eliminates the tedious and time-consuming steps of graphical targeting approaches. Use it to complement the graphical techniques in the design and retrofit of water networks.

Pipeline Pressure Drop: A New Design Correlation

June
2006
Fluids and Solids Handling
Roger Gilmont
A linear equation has been derived to accurately calculate the flowrate of fluids in the laminar and turbulent regions, and to derive an equation for use in the transitional regions.

Building Models from Simulator Runs

January
2006
Computational Methods
Magali de Macedo, Aad van Veldhoven
The design-of-experiments approach has the advantage of providing the framework to build complex models with minimum use of time and effort.
