Herein, we present a surogate model based bayesian optimization and parameter estimation for a CO2 capture process with a new water lean solvent. The water lean solvent, K2Sol, is a sterically hindered diamine and the hindered amine site makes K2Sol easily forms bicarbonate resulting the high absorption capacity. The surogate model based optimization and parameter estimation are carried out according to input and output relationship of experiments, thus expensive optimization model construction and property estimation can be avoided. According to the pilot plant experiment, the optimum regeneration energy of Monoethanolamine (MEA) and K2Sol respectively shows 4.3 and 2.8 GJ/tCO2 indicating that K2Sol requires only 65% of regeneration energy of MEA. |
