Recently, the light hydrocarbon processing complex (including 2X800000 t/a alkylation unit, 500000 t/a isobutane anti isomerization unit, 1.6 million t/a C1/C2 separation unit, and 1.4 million t/a C3/C4 separation unit) of the second phase project of the 40 million t/a refining and chemical integration project of Zhejiang Petrochemical Co., Ltd., which was designed by the company, was rated as the excellent project of chemical construction in 2022 by the China Association of Chemical Construction Enterprises.

The construction content of Zhejiang Petrochemical Phase II Project is mainly to increase the oil refining capacity of 20 million tons per year, the aromatics production capacity of 6.6 million tons per year and the ethylene production capacity of 1.4 million tons per year.As a sub general institute of oil refining+aromatics, the company has undertaken the engineering design of 30 sets of process units and supporting facilities such as pipeline network and intermediate tank farm in the oil refining area.Among them, the detailed design of the light hydrocarbon processing complex will be started in March 2019, the construction will be started in June 2019, and it will be officially put into production in December 2021.

At present, all process units and system units in the oil refining area of Phase II project are operating at full capacity and stably.
