Welcome to Chemical Engineering Progress
This month we begin a three-part series on compact exchangers by Christopher Haslego and Graham Polley. Here they introduce a procedure for accurately estimating the required heat-transfer area in plate-and-frame heat exchangers. (Parts 2 and 3, which will appear in October and November, cover integrating plate-and-frame exchangers into pinch analysis for new plants and for plant retrofits.)

Size Depressurization and Relief Devices for Pressurized Segments Exposed to Fire
Piping and equipment must withstand fires without rupturing. This can be accomplished by properly designing relief and depressurization systems and using passive fire protection,when needed. Per Salater - Sverre J. Overaa - Elisabeth Kjensjord -
Options for Regenerative Thermal Oxidizers: New, Used or Upgraded?
Do you need additional capacity or better performance from your existing RTO? Here's how to evaluate whether to upgrade the existing unit, purchase a new system, or buy used equipment. James T. Gallo - Rodney J. Schwartz - James T. Cash -
Engineering to Business: Optimizing Asset Utilization Through Process Engineering
Asset owners who integrate the process engineering, operations and business lifecycles of their facilities can improve return-on-capital by up to 4%. Use this virtual-asset model (VAM) to optimize your business assets. Andy Howell - Vikas Dhole - Wayne Sim - Kevin Hanson -
Hydrogen: Liability or Asset?
In a petroleum refinery, viewing hydrogen as an asset rather than a liability can lead to increased profits. The key is in the mindset. A typical investor uses money to make money. This article shows you how to use hydrogen to make money. Nick Hallale - Ian Moore - Dennis Vauk -
