摘要
在对炼油厂综合用能分析的基础上,按照过程系统"三环节"能量综合优化方法,对工业能量转化、利用和回收系统进行优化,制定了主要炼油工艺装置改进、装置间热联合、低温热合理利用以及储运与蒸汽动力系统优化改造的方案和措施,实施后取得显著成效。2011年,原油加工总量达到14.50 Mt,加工损失率为0.38%,累计节电超过2×107 kWh、节约蒸汽255kt,炼油综合能耗降低到2 071MJ/t。
Based on analyzing the comprehensive energy consumption of Maoming Oil Refinery,using process system integration optimizing approaches,optimizing the transformation,utilization and recovery of industrial energy in the whole plant were carried out.Some optimized solutions and measures for saving energy were proposed and mostly were realized,such as improvements in some main refining units,heat integration among units,proper using low-temperature heat,revamping storage-transportation and steam power system.Successful results were achieved,in 2011,the total crude processing capacity reached 14.5 million tons with processing loss of 0.38% only,the comprehensive energy consumption of the whole plant was reduced to 2 071 MJ/t,in which saving electricity more than 20 million kWh and steam 255 kt.
