Emergency pressure relief calculations using the computer package: RELIEf

摘要

The computer package RELIEF has been specifically designed to model the transient one-dimensional fluid dynamic behaviour of multicomponent chemically reacting mixtures in batch-type chemical reactors or storage vessels. The physical model that describes the above phenomena is coupled to a sophisticated input/output processor that creates an environment in which a problem can be easily set up and executed and the results investigated. A complete "stand alone" package is thus created in which much attention has been devoted to minimising the input requirements and model running time. This has made the package an ideal tool for performing parametric studies of relief scenarios, and highlighting the key phenomena that control the process being studied. A number of emergency pressure relief calculations are presented that illustrate the capabilities of RELIEF.
