Simulation and optimization of carbon dioxide absorber and stripper is studied. Simulation is based on mathematical which is model derived using equilibrium of chemical reaction adopted from Deshmukh model. The model is then solved using Newton Raphson method. Simulation results are compared with actual data obtained from carbon dioxide absorber and stripper. Objective of the optimization port is the optimum operating conditions which give minimum operating cost of the unit. The optimum operating cost is found to be depended on energy utilized in reboiler. Important variables are concentration of carbon dioxide and flow rate of inlet gas stream. Control variable are flow rate of inlet liquid stream concentration and temperature of monoethanolamine The simulation result show that calculated carbon dioxide concentration in exit gas stream deviate from actual results within approximately 8 - 10%. Liquid exit stream temperature and temperature of exit stream stripper deviate with in approximately 1%. These results are based on carbon dioxide concentration at inlet gas stream in the range of approximate 1 - 3%. The optimization results show that carbon dioxide concentration at inlet gas stream is the only variable encountered in this study, other important and control variables cannot be adjusted because of actual operating condition of the unit. The optimization of the unit is inconclusive.
