23.2 billion! An environmental impact assessment of the ethylene transformation project of Lanzhou Petrochemical Transformation and Upgrading

On December 29, PetroChina Lanzhou Petrochemical Company's Lanzhou Petrochemical Transformation and Upgrading Ethylene Transformation Project carried out the first public environmental impact assessment
.

The following is the basic information of
the project.

The construction site of Lanzhou Petrochemical Transformation and Upgrading Ethylene Transformation Project is located in the refinery area, fertilizer ethylene plant and petrochemical rubber plant of Lanzhou Petrochemical Company, with a total investment of about 23.
17 billion yuan and an annual operating time of 8,000 hours.

The main projects include: the construction of a 200,000-ton/year carbon two recovery unit and a 50,000-ton/year PSA unit in the refinery; The chemical park built a new 1.
2 million tons/year ethylene plant (a new 1.
2 million tons/year cracking + quenching unit, and a 460,000 tons/year ethylene post-separation system), a 100,000-ton/year UHMWPE plant, a 20,000-ton/year octene-1 plant, a 100,000-ton/year POE plant, a 140,000-ton/year EVA unit, a 400,000-ton/year PP unit, a 300,000-ton/year HDPE, 800,000 tons/year pyrolysis gasoline hydrogenation, and 800,000 tons/year aromatic extraction; 160,000 tons/year ethylene ethane concentration in the refining area; Transform a set of catalytic cracking unit, 3 million tons/year diesel hydrogenation unit and 1.
2 million tons/year diesel hydrogenation unit
in the refining area.
Auxiliary devices include: new 2000t/h waste heat recovery station (hot water station), 2*270t/h start-up boiler, 1 flare system, hazardous chemical warehouse, product warehouse, class A and B warehouse, propylene warehouse, chemical park storage and transportation facilities (tank farm), automobile loading and unloading facilities, liquid ammonia storage tanks and unloading facilities, special railway lines in the plant, hazardous waste temporary storage warehouse (field), etc
.

The projects put into use in advance include: 110kv temporary substation, chemical park 1# fire pump station, automobile loading and unloading facilities, east tank farm, propylene warehouse, waste alkali treatment device, boiler deaeration water station, chemical park pipe gallery (part), mutual supply pipe gallery (part), part of the pipeline (throwing pipe), part of the underground pipe network (part), relocation of flare condensate tank (relocation of three high-level tanks), hazardous waste warehouse, environmental catalysis pilot base of State Key Laboratory of Petroleum and Petrochemical Pollutants Control and Treatment, chemical library
