摘要
根据原料成本、加工费用、销售收入及天然气补网费用核算了干气提浓装置对炼化一体效益。由于增加购买天然气补充瓦斯管网的费用,武汉分公司(即炼厂部分)单位产品效益为-707元/t;但是利用富乙烯气做乙烯原料降低了原料成本和裂解炉操作费用,中韩乙烯合资公司部分的单位产品效益为2 613元/t;炼化一体核算单位效益为1 906元/t,总效益约为6 442.29万元/t。还讨论了装置运行存在的原料气组成与设计偏差大、原料气总硫超标、冷干机压降大及长输管线冻凝等问题,并提出了气柜气单独脱硫、增加浅冷油吸收单元、提高上游装置操作压力及增加产品气回温换热器等一系列的解决措施。
Based on material cost, processing cost, sales revenue and pipe network construction fee for natural gas, the impact of dry gas enriching unit on refining-chemical integration was calculated approximately. Due to adding the cost of purchasing natural gas for supplementing gas pipe network, one ton product can bring benefit of-707 Yuan in Wuhan Petrochemical Company（refinery section）; Due to using ethylene-rich gas as ethylene feedstock to decrease raw material cost and pyrolyzer＇s operation cost, one ton product can bring benefit of 2 613 Yuan in China-South Korea Joint Venture Company; the total benefit of refining-chemical integration was 64.422 9 million Yuan in 2014, and the unit benefit of product was 1 906 Yuan per ton. Some problems in running of the unit were also discussed, and the corresponding countermeasures were put forward.
