摘　　要：煤气化合成气为核心的多联供多联产系统是能源化工可持续发展的重要组成部分,联供因子和联产因子是影响多联供多联产系统性能的两个关键因素。以天然气辅助煤多联供甲醇电多联产系统为例,根据其结构特性,提出以甲醇合成模块中未反应合成气进燃气-蒸汽联合循环发电装置的分流比率为联产因子,以进系统天然气的与原煤的的比值为联供因子,考察系统规模、损率、产品成本分别跟随联供因子和联产因子单因素变量变化规律,并讨论煤炭价格和天然气价格对系统产品成本的影响。Syngas based co-feed and co-production （COCO） system is one of the important parts of sustainable development for energy and chemical industries. Co-feed and co-production factors are two key elements to affect the performance of COCO system. The coal/natural gas co-feed and electricity/methanol co-production system is proposed as the case study. Co-feed factor is defined as the separate ratio of unreacted syngas from methanol reactor unit to gas-steam combined cycle power generator; co-production factor is defined as the exergy ratio between natural gas and coal. The effect of the proposed factors on the methanol yield, exergy loss rate, and product cost was investigated systematically. The effect of the prices of coal and natural gas on product cost was also investigated. The corresponding effect relations were discussed.
