PetroChina Guangxi newly built 1.2 million tons of ethylene / 200,000 tons of PO / 400,000 tons of PP, etc.!

On December 13, PetroChina Guangxi Petrochemical refining and chemical integration upgrade project carried out an environmental impact assessment announcement.
Guangxi Petrochemical plans to build a new 1.
2 million tons/year ethylene and a series of downstream units on the basis of the existing 10 million tons/year oil refining, with a total of 14 sets of devices, including ethylene, full density polyethylene, high density polyethylene, EVA, polypropylene and propylene oxide,
etc.

Project Name: PetroChina Guangxi Petrochemical Company Refining and Chemical Integration Transformation and Upgrading Project

Construction nature: New ethylene and refinery renovation

Project construction site: The project is located in Qinzhou Petrochemical Industrial Park, Guangxi Qinzhou Port Technology Development Zone, Qinzhou City.
For expansion, the chemical industry area is mainly built within the scope of newly acquired land, and the dock storage area is reconstructed and expanded on the basis of the existing dock storage area of ​​Guangxi Petrochemical Company
.

The total investment of the project: 36,957,140,000 yuan
.

Covering area: The new facilities of this project cover an area of ​​about 3,045,028 square meters, of which the newly added area is about 3,020,000 square meters, and the rest are carried out within the existing area of ​​Guangxi Petrochemical
.

Production time: The designed annual operation time of the refinery unit is 8400h, the designed annual operation time of the chemical unit is 8000h, and the designed annual operation time of the polystyrene unit is 7200h
.

Project capacity: This project has a new capacity of 1,368 people, with four shifts and two operations
.

Construction period: The total construction period of the project is about 36 months
.

Construction content and scale: The project is to build a new 1.
2 million tons/year ethylene and downstream unit on the basis of Guangxi Petrochemical's existing primary crude oil processing capacity of 10 million tons/year, so as to realize the transformation and upgrading of refining and chemical integration
.

Relying on the existing 30 sets of main production units, the refining block will build a new 2 million tons/year diesel adsorption dearomatization unit and a 400,000 tons/year carbon 2 recovery unit (including 100,000 tons of catalytic dry gas carbon 2 recovery unit and 400,000 tons of carbon 2 recovery unit) C2 recovery unit, built in the chemical zone)
.
After the completion of the project, the overall processing flow of the refining block will remain unchanged, and the product plan of some refining products will remain the same as the status quo, but the annual output of gasoline and diesel will be reduced, and a large amount of high-quality raw materials will be provided for the downstream ethylene unit
.

Chemical block plant construction scale

In the chemical block, 14 sets of main chemical plants are newly built, including 1.
2 million tons/year ethylene unit, 550,000 tons/year pyrolysis gasoline hydrogenation unit/styrene extraction unit, 180,000 tons/year butadiene extraction unit, 10 /60,000 tons/year MTBE/butene-1 unit, 350,000 tons/year aromatics extraction unit, 400,000 tons/year full density polyethylene unit (FDPE), 300,000 tons/year high density polyethylene unit (HDPE) ), 300,000 tons/year tubular ethylene-vinyl acetate unit (EVA), 100,000 tons/year kettle ethylene-vinyl acetate unit (H-EVA), 400,000 tons/year polypropylene unit (PP), 50,000 tons/year hexene-1 unit, 27/600,000 tons/year propylene oxide/styrene unit (PO/SM) and 12/80,000 tons/year solution-polymerized styrene-butadiene rubber integrated unit (SSBR/SBS)

It mainly processes different types of cracked raw materials from the oil refining block to produce high density polyethylene (HDPE), linear low density polyethylene (LLDPE), ethylene vinyl acetate (EVA), polypropylene (PP), butadiene, methyl alcohol tert-butyl ether (MTBE), butene-1, hexene-1, solution styrene-butadiene rubber (SSBR), styrene-butadiene-styrene (SBS), propylene oxide (PO), styrene (SM), polystyrene (PS) and other major chemical products
.
At the same time, the whole plant's environmental protection measures, storage and transportation system, and public works will be newly built, renovated and expanded or reused according to the process flow
.

Four new 5,000-cubic-meter styrene storage tanks will be built in the reserved area of ​​the dock storage area; in addition, the existing 13# berth benzene loading facilities will be changed to benzene unloading facilities, and the 11# berth 2 gasoline loading and unloading arms and 1 The diesel loading and unloading arms were changed to benzene, toluene and xylene loading and unloading arms respectively, and styrene loading facilities were added at berth 9#
.
At the same time, the environmental protection measures, storage and transportation system, and public works of the wharf reservoir area and wharf will be newly built, renovated, expanded or repurposed according to the technological process
.
