http://www.che.com Chemical Engineering en-us 2013 Thu, 23 May 2013 17:10:30 EDT Shell-and-tube heat exchangers are one of the most important and commonly used process equipment items in the chemical process industries (CPI). While the actual design will likely be done by a specialist at an equipment vendor or within your own company, you still need to fill out a process datasheet for each heat exchanger and in due course, review the vendor’s detailed proposal.  This article shows you the basics of specifying and selecting shell-and-tube heat exchangers: the process information and preliminary design decisions needed to fill out the datasheet, and how to check any corresponding assumptions made by the vendor.... http://www.che.com/processing_and_handling/thermal_and_energy_mgmt/heat_exchangers_condensers_and_coolers/10477.html Wed, 1 May 2013 0:00:00 EDT The HVF-Freezer (high-velocity freezer) is said to be an improved freezer concept based on existing impingement-freezer technology.
