Abstract

In this chapter, the implementation in Aspen Plus® of the CO2 post-combustion capture by reactive absorption-stripping process model is presented. Components and thermodynamics in the Properties Environment are considered in the first place. Then, in the Simulation environment, the set-up of the RadFrac™ model—Rate-Based mode, considered mandatory for this kind of process, is extensively described. The attention is especially focused on the appropriate definition of the rate-based model parameters needed for the discretization of the liquid film. A section is dedicated to the examination of the system fluid dynamics by means of the evaluation of the Peclet number and the number of segments analysis. In particular, it is highlighted how this procedure is of fundamental importance to obtain the correct solution of the resulting system of algebraic equations.
