April
2002
Heat Transfer
Graham T. Polley, Mohamad R. Jafari Nasr
Following this procedure to identify a basic exchanger geometry without performing a full exchanger design and to evaluate where and when heat transfer enhancement can be of benefit.

Team Up with a Consultant for Process Equipment Selection

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.

Choosing Specialty Metals for Corrosion-Sensitive Equipment

July
2010
Back To Basics
Dean Gambale
Specialty metals should be considered for processes that push beyond the corrosion limits of steel. New composites and surface alloy technologies expand the options for defending against corrosion.

Burning Bright: Trends in Process Integration

July
2001
Process Development
Nick  Hallale 
Process integration has a far wider scope and touches every area of process design. Industries are making more money from their raw materials and capital assets, while becoming cleaner and more sustainable.

Evaluating the Economics of Desalination

December
2002
Heat Transfer
Hisham M. Ettouney, Hisham T. El-Dessouky, Peter J. Gowin, Ron S. Faibish
This article presents an in-depth analysis of thermal and membrane desalination economics and outlines a simple procedure for calculating the unit product cost for various desalination processes.

Guidelines for Selecting Sterilizing-Grade Filters

March
2005
Fluids and Solids Handling
Monica Cardona, Philip Blosse
Determine if your bioprocess needs a sterilizing grade filter, and if so, use these guidelines to select the proper one for your application.

Properly Select Equipment for SIP Systems

August
2007
Fluids and Solids Handling
Tony George
Sterilization-in-place (SIP) systems are essential to the operation of many pharmaceutical and biotech facilities. This article reviews design considerations, selection criteria and performance expectations for control valves, regulators, isolation...

Developing Screening Cost Estimates

July
2011
Process Development
Richard P. Palluzi, P.E.
Making decisions based on estimates derived from weak data is counterproductive. Use this established methodology to prepare scoping and screening cost estimates for pilot plants quickly and accurately.
