DEVELOPMENT AND APPLICATION OF PROBLEM SPECIFIC LOCAL-PROCESS SIMULATORS IN CAPE

A methodology for generating problem specific ''local'' simulators fro m a base (modular) simulator is presented. Based on an analysis of the process flowsheet and the simulation problem, the flowsheet is decomp osed into parts that are solved with the modular approach and parts th at are solved with the equation oriented approach. Also, the use of op timization techniques has been investigated to solve a part of the flo wsheet. The application of the methodology has been tested in terms of an existing modular steady state simulator. Numerical examples of sol ution of parts of flowsheets with the equation oriented approach or th e optimization technique from within the modular simulator are present ed.
