近年来,Shell致力于石化装置和炼油厂的一体化进程,以提高赢利能力。最近,Shell表示,该公司将依靠裂解轻质原料来继续降低美国海湾Deer Park和Norco裂解联合装置的生产成本。“在以后几年里,将进行气体和液体原料之间的转换,这一计划包括将裂解装置改用包括低价乙烷和炼厂尾气的气体原料”。近几年,Shell把美国海湾的裂解能力降低了22%,裂解能力由裂解75%液体馏分和25%气体改为裂解75%气体。
In recent years, Shell has been committed to the integration of petrochemical plants and refineries to improve profitability. Recently, Shell said it will rely on cracking lighter feedstocks to continue reducing production costs for the Deer Park and Norco Crackers in the U.S. Gulf. “In the coming years, there will be a switch between gas and liquid feedstocks, which will include switching the cracker to a gas feedstock that includes low-cost ethane and refinery off gases.” In recent years, Shell has reduced the cracking capacity of the U.S. Gulf by 22%. Its cracking capacity has changed from cracking 75% liquid fraction and 25% gas to cracking 75% gas.
