Design and Rate Shell and Tube Heat Exchangers

Course Id:  EHX101   |   Duration:  2.00 day(s)   |   CEUs Awarded:  1.4   |   Level:  Introductory


Course Objective

A common engineering task is the design of a new heat exchanger, or evaluation of an existing exchanger to verify it will perform properly in a new service.  A successful design requires engineers to accurately predict exchanger thermal performance, pressure drop, and risk of vibration in the field.  It is therefore advisable to rigorously model exchangers with detailed calculations to provide more confidence in the results than would be obtained utilizing simplified ‘short-cut’ calculations.  Aspen Exchanger Design and Rating has the capability to perform sophisticated exchanger calculations, which account for equipment geometry, materials, and operating conditions.  This technology can help reduce capital costs by enabling engineers to optimally-design exchangers.
 

Course Overview

Effectively navigate and manage the Aspen Shell & Tube Exchanger user interface. Perform multiple heat exchanger calculation types, easily review results, and draw meaningful conclusions on exchanger performance. Troubleshoot shell and tube heat exchangers for poor thermal performance and vibration problems. Understand the various equipment design options specific to shell and tube heat exchangers. Integrate Aspen Shell & Tube Exchanger capabilities with process simulation data in Aspen Plus and Aspen HYSYS.
