http://www.che.com Chemical Engineering en-us 2013 Sat, 25 May 2013 23:43:50 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 Occasionally, direct fired heaters that have operated satisfactorily for long periods of time subsequent to startup develop operating problems that do not allow for operation at design conditions, as specified in the manufacturers API data sheets for the heater.... http://www.che.com/processing_and_handling/thermal_and_energy_mgmt/kilns_ovens_and_furnaces/10471.html Wed, 1 May 2013 0:00:00 EDT Larson Electronics The recently launched WALBL-2 x 1000WMH Boiler Light is a telescoping light tower with a folding boom that is designed to allow versatile deployment and high-output illumination.

Much coal-fired power is being replaced by these technologies. In addition, though, simple- and combined-cycle units are well suited for power and steam production at industrial facilities.... http://www.che.com/processing_and_handling/thermal_and_energy_mgmt/power_generation_and_transmission/10392.html Mon, 1 Apr 2013 0:00:00 EDT The CS10 Clean Steam Separator with enhanced surface finish has been engineered to overcome problems associated with wet steam and ensures the correct quality of steam is supplied to the point of use... http://www.che.com/processing_and_handling/thermal_and_energy_mgmt/boilers_and_steam_handling/10274.html Fri, 1 Mar 2013 0:00:00 EST The HVF-Freezer (high-velocity freezer) is said to be an improved freezer concept based on existing impingement-freezer technology. The new HVF uses high-velocity air jets to quickly reduce the outer layer... http://www.che.com/processing_and_handling/thermal_and_energy_mgmt/heat_exchangers_condensers_and_coolers/10275.html Fri, 1 Mar 2013 0:00:00 EST Changing out used heat-transfer fluid is critical to the efficiency of a heat-transfer fluid system. A well-operated heat-transfer-fluid system can enable efficient production, fewer shut-downs, less maintenance time and lower costs. In order to maintain a sound heat-transfer system, it is critical that the fluid is well cared for and, when the fluid reaches the end of its life, that it is efficiently changed out for new fluid. As fluid is used and ages, it can degrade to a point where it is no longer providing sufficient heat transfer for the process. When this occurs, the fluid must be... http://www.che.com/processing_and_handling/thermal_and_energy_mgmt/heat_transfer_media/10299.html Fri, 1 Mar 2013 0:00:00 EST The carbon-fiber pilot line consists of an oxidation furnace, carbonization furnace and a graphitization furnace, The four-zone oxidation furnace... http://www.che.com/processing_and_handling/thermal_and_energy_mgmt/kilns_ovens_and_furnaces/10272.html Fri, 1 Mar 2013 0:00:00 EST Depending on the steam pressure required, the specific approach of the water treatment may be shifted to account for a variety of issues. The following outlines water treatment requirements at different steam pressures and some of the important reactions at high- and low-pressure ranges.... http://www.che.com/processing_and_handling/thermal_and_energy_mgmt/boilers_and_steam_handling/10176.html Fri, 1 Feb 2013 0:00:00 EST
