03. (20 points). An absorption/stripping process is operating at constant temperature and atmospheric pressure. This system is a proposed addition to a coal fired power plant in an attempt to minimize the amount of CO2 released by the power plant. The process has a 90% recovery rate of CO2 and it utilizes a 32.5 weight% monoethanolamine solution as the lean amine absorbent in the system. The absorption column used in the process has a loading of 0.17 (mol CO2/mol MEA).
