Stripping Section Design Analysis
The analysis of the stripping section design procedure of an industrial CO2-MEA post-combustion capture system is considered in this chapter. An alternative plant configuration without reflux is adopted with the aim of reducing the consumption of steam in the reboiler. Then, the most important operating parameters are described in detail. After the rich solvent characterization, the effect of the packing height on the reboiler duty and the column diameter is analyzed. Due to the impossibility to use the classic minimum and effective stripping agent design approach, a criterion for the definition of the stripper packing height based on the analysis of the liquid temperature gradient profiles is proposed.
