Guangxi Petrochemical: Successful First Trial Run!

Guangxi Petrochemical is a single-series integrated ten-million-ton refinery. The project adopts a full hydrogenation process flow, utilizing internationally advanced technologies such as UOP and DOW Chemical. It offers advantages like high safety and environmental protection levels, strong adaptability to crude oil processing, complete supporting facilities, and high-quality clean products. The refinery covers an area of over 3,800 acres and currently has 23 main process units including 10 million tons/year atmospheric and vacuum distillation, 3.5 million tons/year heavy oil catalytic cracking, 2.2 million tons/year continuous reforming, 4 million tons/year residue hydrodesulfurization, along with a comprehensive utility engineering system. All processed crude oil is imported from overseas, primarily sulfur-containing crude oil from the Middle East. The products include gasoline, diesel, jet fuel, aromatics, polypropylene, liquefied gas, asphalt, and sulfur. It is based in Guangxi and serves surrounding areas, with exports to countries such as Singapore and Australia.

The project involves the construction of a new 1.2 million tons per year ethylene and downstream units on the basis of the existing 10 million tons per year primary crude oil processing capacity of Guangxi Petrochemical, thereby achieving an integrated refining and chemical transformation and upgrade.

The refining block relies on the existing 30 main production units, constructing a new 2 million tons/year diesel adsorption desulfurization unit and a 400,000 tons/year C2 recovery unit (including a 100,000 tons/year catalytic dry gas C2 recovery unit and a 400,000 tons/year C2 recovery unit, built in the chemical area), while shutting down 2 main production units. After the project's completion, the overall processing flow of the refining block remains unchanged, and the product scheme of the refining section remains consistent with the current situation. However, the annual production of gasoline and diesel will decrease, providing a large amount of high-quality feedstock for the downstream ethylene unit.

The chemical block will construct 14 main chemical units, including a 1.2 million tons per year ethylene unit, a 550 thousand tons per year cracked gasoline hydrogenation unit/styrene extraction joint unit, a 180 thousand tons per year butadiene extraction unit, a 100/60 thousand tons per year MTBE/butene-1 unit, a 350 thousand tons per year aromatic extraction unit, a 400 thousand tons per year full-density polyethylene unit (FDPE), a 300 thousand tons per year high-density polyethylene unit (HDPE), a 300 thousand tons per year tubular ethylene-vinyl acetate unit (EVA), a 100 thousand tons per year kettle ethylene-vinyl acetate unit (H-EVA), a 400 thousand tons per year polypropylene unit (PP), a 50 thousand tons per year hexene-1 unit, a 270/600 thousand tons per year propylene oxide/styrene unit (PO/SM), a 300 thousand tons per year polystyrene unit (PS), and a 120/80 thousand tons per year solution polymerized styrene-butadiene rubber integrated unit (SSBR/SBS).

Upon completion and commissioning, the project will facilitate the transformation of PetroChina Guangxi Petrochemical from a "fuel-type" company to one focused on "chemical products and organic materials." This will enable a shift from a refining-dominated foundational industry to a modernized "base + high-end" energy chemical materials industry. It is of significant importance in filling the gap in the high-end chemical new materials industry in the region, meeting market demands along the new western land-sea corridor, and establishing a trillion-level petrochemical industry cluster oriented towards ASEAN.
