[Haichuan Engineering News] CNPC Guangxi Petrochemical’s new 1.2 million tons per year ethylene plant and 14 other chemical production units are now under public disclosure
Thread Content
14 major chemical production units, including one producing 1.2 million tons of ethylene, will be built. Project name: China National Petroleum Corporation Guangxi Petrochemical Company’s Integration and Upgrading Project for Refining and Chemical Production. Nature of the construction: Construction of new ethylene production facilities and upgrades to existing refining facilities. Location: The project is situated within the Guangxi Qinzhou Petrochemical Industrial Park in the Qinzhou Port Technology Development Zone, Qinzhou City. It consists of a refining area, a chemical production area, and a port and storage area. The refining area will be expanded and upgraded using the existing facilities of Guangxi Petrochemical Company as well as its current asphalt production facilities; the chemical production area will be built on newly acquired land; while the port and storage area will be expanded and upgraded using the existing port and storage facilities of Guangxi Petrochemical Company. Construction content and scale: This project involves building an ethylene and downstream facility with a capacity of 120×104 t/a on top of Guangxi Petrochemical’s existing crude oil processing capacity of 1000×104 t/a, thereby achieving integrated transformation and upgrading of the refining and petrochemical industries. Relying on the existing 30 main production units, the refining complex will incorporate a new diesel adsorption dearomatization unit with a capacity of 200×104 t/a, as well as a carbon dioxide recovery unit with a capacity of 40×104 t/a (comprising a 10×104 t/a catalytic dry gas carbon dioxide recovery unit and a 40×104 t/a carbon dioxide recovery unit), both of which will be located in the chemical industry zone. Upon completion of the project, the overall processing flow in the refining section remains unchanged, and the product portfolio for refined products stays as it is; however, the annual production of gasoline and diesel will decrease, while high-quality raw materials will be supplied to the downstream ethylene plants.
In the chemical processing zone, 14 new chemical production units will be constructed, including an ethylene plant with a capacity of 120×104 t/a, a pyrolysis gasoline hydrogenation/styrene extraction complex plant with a capacity of 55×104 t/a, a butadiene extraction plant with a capacity of 18×104 t/a, MTBE/butene-1 plants with capacities of 10/6×104 t/a each, an aromatic extraction plant with a capacity of 35×104 t/a, a full-density polyethylene plant (FDPE) with a capacity of 40×104 t/a, a high-density polyethylene plant (HDPE) with a capacity of 30×104 t/a, a tubular ethylene-vinyl acetate plant (EVA) with a capacity of 30×104 t/a, a batch-type ethylene-vinyl acetate plant (H-EVA) with a capacity of 10×104 t/a, a polypropylene plant (PP) with a capacity of 40×104 t/a, a hexene-1 plant with a capacity of 5×104 t/a, a propylene oxide/styrene plant (PO/SM) with capacities of 27/60×104 t/a each, and an solution-stirred styrene-butadiene rubber integrated plant (SSBR/SBS) with a capacity of 12/8×104 t/a. It primarily processes various types of cracking feedstocks derived from the refining sector to produce key chemical products such as high-density polyethylene (HDPE), linear low-density polyethylene (LLDPE), ethylene-vinyl acetate (EVA), polypropylene (PP), butadiene, methyl tert-butyl ether (MTBE), butene-1, hexene-1, solvated styrene-butadiene rubber (SSBR), styrene-butadiene-styrene (SBS), propylene oxide (PO), styrene (SM), and polystyrene (PS). At the same time, the plant’s environmental protection measures, storage and transportation systems, as well as utility systems will be newly constructed, upgraded, or made use of existing facilities based on the process flow. 4 new styrene storage tanks with a capacity of 5,000 m3 are to be built in the reserved area of the dockyard ； In addition, the benzene loading facility at the existing berth 13# at the terminal will be converted into a benzene unloading facility; the two gasoline loading/unloading arms and one diesel loading/unloading arm at berth 11# will be converted respectively into benzene, toluene, and xylene loading/unloading arms; and a styrene loading facility will be added at berth 9#. At the same time, the environmental protection measures for the dock storage areas and docks, as well as the storage and transportation systems and utility systems, will be newly constructed, upgraded, or made use of existing facilities based on the specific process flows.
