甲醇裂解热化学余热回收CCHP系统设计与优化OA

A CCHP system combined with thermochemi-cal waste heat recovery from methanol cracking(here-inafter referred to as the combined CCHP system)is proposed,and the MOPSO algorithm is adopted for the optimization analysis of the system.A reference CCHP system without a methanol cracking thermochemical waste heat recovery system or fuel cell is taken as the comparison object to evaluate the comprehensive costs of the two systems.Compared to the reference CCHP system,the combined CCHP system exhibits lower natural gas consumption and lower electricity pur-chased from the grid,primarily because the thermo-chemical waste heat recovery system enhances the sys-tem's power generation capacity.Benefiting from lower environmental management costs,the combined CCHP system achieves a lower comprehensive cost.
