Publication number: 20230285891Abstract: The invention relates to a low-cost and high-efficiency absorption-desorption decoupling method for contaminant-CO2 synergistic capture. According to the method, an optimization model of absorption-desorption decoupling control for contaminant-CO2 synergistic capture under different working conditions is built, the optimization objective is to obtain high-purity liquid contaminants and CO2 at low cost and efficiently, and an adaptive penalty function is constructed to transform a solution of a constrained optimization problem into that of an unconstrained optimization problem, thereby controlling parameters in a real-time, precise and stable manner. Moreover, supported by means of flue gas pre-scrubbing and cooling, multi-stage intercooling and column-top demisting, the method of the present invention achieves efficient capture of contaminants and CO2.Type: ApplicationFiled: March 11, 2023Publication date: September 14, 2023Inventors: CHENGHANG ZHENG, XIANG GAO, CHANG LIU, CAN ZHOU, YONGXIN ZHANG, YOU ZHANG, YANG ZHANG, QINWU LI, WEIGUO WENG, WEIHONG WU, XIAO ZHANG, TAO WANG
