Object Oriented Modeling of Single and Multi-Bed Pressure Swing Adsorption Processes using OpenModelica

Abstract

Pressure Swing Adsorption has been implemented to produce pure oxygen from air. Its model is solved using the methods of finite difference and orthogonal collocation on finite elements. Discrete events of this process are modelled using state graphs. Solution to the PSA process using a single bed is presented. With two beds, it is shown that it is possible to produce oxygen continuously. All of these have been done using OpenModelica, and the code is released as open source.
