10/18/99 ASPEN Introduction 2 WHAT IS ASPEN? uA computer program for steady-state process simulation (a.k.a. process Flowsheeting) uDeveloped for the simulation of ð Chemical & Petrochemical Processes ð Coal-based Processes ð Petroleum Refining ð Polymer Processes uOne of many commercially available flowsheeting programs such as ð PRO II (Simulation Sciences) ð HYSIM (Hyprotech) ð ChemCad (Chemstation)
HOW DOES ASPEN WORK? Basic unit is the block model E Unit operations Distillation Columns, Reactors, etc.) E Related operations such as piping Q User assembles flowsheet model by selecting and connecting appropriate Block models and specifying Block model parameters 0 ASPEN solves sequentially for output streams given input streams and Block model parameters 10/1899 ASPen Introduction 3
