摘　　要：开展催化重整装置产品碳足迹评价对于构建炼油工业和经济社会的产品碳足迹评价体系具有重要意义。石化生产装置的能量利用状况是影响碳排放的重要因素。按照催化重整装置产品物料在生产加工过程中的能量演化进行碳足迹评价,提出了包括搭建工艺流程、建立排放源清单、分析物料平衡、排放分配以及计算碳足迹等步骤的评价方法,并以某1.0 Mt a催化重整装置为案例计算产品碳足迹。由于不同产品经历的加工流程不同,其碳足迹会有较大差别,其中副产氢气的CO_(2)排放量较高,为1613.079 kg/t,苯和甲苯的CO_(2)排放量分别高达359.957 kg/t和428.924 kg/t;而且,由产品碳足迹计算的碳排放量与排放源清单具有较好的一致性。The carbon footprint assessment for the products from catalytic reforming unit is of great significance for constructing carbon footprint system for the refining industry and the economy and society.As the energy utilization status of the petrochemical process unit is an important factor affecting carbon emissions,the carbon footprint assessment based on the energy status evolution of product materials in the process of catalytic reforming unit was studied.The assessment method which includes building a process flow,establishing an emission source list,analyzing material balance,emission distribution,and carbon footprint calculation was proposed.The products carbon footprint was calculated by taking a 1.0 Mt a catalytic reforming unit as a case study.Due to the different processing flow for different products,their carbon footprint will vary greatly.Among them,the by-product hydrogen has a higher carbon footprint of 1613.079 kg t,while benzene and toluene have carbon footprints of 359.957 kg/t and 428.924 kg/t,respectively;meanwhile,the carbon emissions calculated from the product carbon footprint have good consistency with that calculated from the emission source inventory.
