摘要
中国石油四川石化公司800 kt/a乙烯装置依托10000 kt/a炼油项目而建,采用美国S&W公司专利技术。充分利用炼化一体化企业内部原料互供的优势,通过裂解一次加工产生的石脑油、拔头油等,以及二次加工产生的重整精制油、加氢裂化石脑油、液化气等,生产乙烯、丙烯、丁二烯等主要化工产品。原设计进料有加氢裂化尾油、轻重石脑油及轻烃。因炼油负荷及原油的变化,造成作为乙烯装置主要原料的石脑油品质变差,严重影响装置乙烯收率。从加工效益上看,评价及优化裂解原料,对装置提高产品收率具有重要意义。
The 800 kt/a ethylene plant of PetroChina Sichuan Petrochemical Company is built on the basis of a 10000 kt/a oil refining project,and the patented technology of S&W Company in the United States is adopted.The project makes full use of the advantages of mutual supply of raw materials in the refining and chemical integration enterprise to produce ethylene,propylene,butadiene and other major chemical products by cracking the naphtha and topping oil from primary processing as well as the reformate refined oil,hydrocracking naphtha and liquefied gas from secondary processing.The original design feed includes hydrocracking tail oil,light naphtha,heavy naphtha and light hydrocarbon.Due to the changes in refining load and crude oil,the quality of naphtha,which is the main feed to ethylene plant,gets worse,seriously affecting the ethylene yield of the plant.From the perspective of processing efficiency,the evaluation and optimization of cracking feedstock is of great significance for improving the product yield of the plant.
