Recently, as the leading project to build a national petrochemical industry base in Tianjin, Sinopec's Tianjin million-ton ethylene project started its capacity expansion and transformation for the first time in 10 years. At present, the project has started construction and is expected to be completed and put into operation in April 2021. By then, the project's production capacity will reach 1.3 million tons per year, and the production capacity of a single set of equipment will also be at the forefront of similar domestic projects.

The 1.3 million ton/year ethylene capacity expansion and transformation project includes the construction of a new 200,000 ton/young oil cracking furnace, the addition of cold boxes, the reformation of cracked gas compressors, propylene compressors and binary refrigeration compressors, and the replacement of ethylene and propylene rectification towers Inside the tower, three sets of 2000 cubic meters of ethylene spherical tanks, one set of 1500 cubic meters of ethylene low-temperature storage tank and low-temperature ethylene loading system, new high-pressure fire pumping station, circulating water cooling tower and circulating water pump were newly built. The raw materials of the project can be imported from overseas ethane resources based on the ethane contract between Saudi Basic Industries Corporation and North America, and the ethane offloading, storage and transportation facilities of Sinopec Natural Gas Branch in Nangang.
