Thermal Separation: An Approach for a Modelica Library for Absorption, Adsorption and Rectification

Abstract

Due to its objected-oriented design Modelica is pre- destinated to describe chemical engineering unit oper- ations. Still only few activity on this field is published. This paper introduces a library which covers three of four major thermal seperation processes: absorption, adsorption and rectification. Additionally an extension of the ExternalMedia li- brary is presented that allows the connection to ther- modynamic and physical property packages for two phase mixtures. Also a possible forecast to an imple- mentation of a CAPE-OPEN interface is made, allow- ing the use of a plurality of established chemical data packages.
