摘要:针对复杂市场环境下4种典型焦化生产模式的优选问题,建立了物质流与价值流耦合模型,分析了不同情景下4种模式的物质输入输出及相应的价值流转过程,比较了资源增值效率指标。结果表明,液化天然气油苯加工模式的增值效率在历史情景下比其它模式高3%~10%:产业链延伸增值效率为焦油粗苯分高出素>纯苯(32%)>焦炉煤气制液化天然气(21%)>焦炉煤气制
甲醇(1%)。在经济上行状态的虚拟情景下,焦炉煤气制甲醇比其它措施增值效率高36%-50%. 关键词:焦化:模式:物质流;价值流:情景分析

Abstract: A coupled model of material flow and value flow was established to solve the selection problem of four typical coking modes under complex market environment. The input and output of the four modes and the corresponding value transfer process in different scenarios were analyzed, and the indicator of resource-added efficiency were compared. The results showed that the value-added efficiency of liquefied natural Gas (LNG)tarbenzene processing mode was 3%~10% higher than that of other modes in historical scenarios. The descending order of added efficiency of the industrial chain extension were naphthalene and benzene separated from tar and crude benzene (32%), LNG from coke oven gas (21%), methanol from coke oven gas (1%). However, in the virtual scenario of
upward economic status, the value-added efficiency of methanol from coke oven gas was 36%~50% higher than other measures. Key werds: coking; mode; material flow; value flow; scenario analysis
1前言
2016年我国焦炭产量达4.49亿吨!],高居世界第一,焦化行业也是典型的高污染行业,其粉尘、SO2和NO 排放量分别约占全国排放量的9%,10%和6%/2).近年来国内经济运行新常态及2015年新环保法的实施,对焦化和钢铁行业去产能[3]、供给侧改革提出了更高要求宏观经济形势变化直接影响了焦化产业,特别是上下游产品价格的波动影响焦炉煤气制甲醇/液化天然气、焦化产品精制等不同焦化生产模式的经济效益,驱需对不同生产模式的效率及市场影响进行深入分析
化工、冶金等过程工业生产模式的评价方法包括基于物质平衡研究物料流量和流向的物质流分析[4]和基于成本计算企业内部价值流转的价值流分析[5,6),下庆才[7建立了国家尺度铁资源利用效率的动态物质流分析模型.Harper等[8建立了钨元素在企业尺度的单元和产品模型以估算产品结构和产量.陈吕军等[9从产品单价、单位产值对应的碳元素等指标分析了精细化工园区碳元素的利用效率.郭颖等10)建立了工业园区碳元素代谢分析模型,以提高碳元素利用效率。杨宁等建立了我国氯元素代谢网络图,用于评估氯工业代谢.毛建素等[12]引入元素价位概念,用不同价位表征原料、产
