Company Size

The comprehensive supporting processing capacity of oil refining reaches 20 million tons/year, and the ethylene production capacity reaches 1.1 million tons/year. At the same time, it has relatively complete supporting systems such as power, ports, railway transportation, crude oil and refined oil pipelines, and 300,000-ton single-point mooring offshore crude oil loading and unloading systems.

Refining Division

The refinery was established in May 1955 and initially processed shale oil. In 1963, it began to process natural crude oil. It has 57 sets of major refining production equipment, including atmospheric and vacuum distillation, catalytic cracking, residue oil hydrogenation, coal-to-hydrogen, and a complete supporting auxiliary production system. It is the first refinery in China with a refining and processing capacity of tens of millions of tons. It has processed 155 types of domestic and foreign crude oil from more than 50 countries and produced more than 90 petroleum products. It is the most complete fuel-lubricant-chemical refinery in China. In early 2014, the largest coal-to-hydrogen unit in China was completed and put into use with high standards. The company has achieved an important transformation from petrochemical business to petrochemical-coal chemical business. 

Chemical Division

The first phase of the 300,000 ton/year ethylene project was completed and put into operation in September 1996, and the second phase of the expansion project was completed and put into operation on September 16, 2006, becoming China's first million-ton ethylene plant. It has 22 sets of main production equipment such as cracking, high-density polyethylene, full-density polyethylene, high-pressure polyethylene, polypropylene, styrene, synthetic rubber, etc., as well as a complete supporting auxiliary production system and public engineering system. It can produce more than 200 varieties of synthetic resins, synthetic rubber, liquid organic chemical raw materials and other products, totaling more than 3 million tons per year.

Key products being produced in the Maoming complex include ethylene, polyethylene, polypropylene, ethylene oxide (EO), ethylene glycol (EG) etc. Ethylene accounts for a major share of its production capacity, 23.4%, at 1 mtpa, followed by polyethylene and polypropylene, with 21.1% (0.9 mtpa) and 15.7% (0.67 mtpa), respectively.

Thermal Power Division

It is mainly responsible for the operation, maintenance and overhaul of the company's steam boilers, steam turbines and steam systems, wind nitrogen systems, and electrical systems, and mainly provides heat and electricity for the company's production. The existing oil refining area has 3 CFB boilers and 3 steam turbine generator sets, with a designed steam supply capacity of 1,030 tons/hour and a power generation capacity of 140,000 kilowatts; the chemical industry area has 2 CFB boilers, 3 oil-gas mixed-firing boilers and 3 steam turbine generator sets, with a designed steam supply capacity of 1,480 tons/hour and a power generation capacity of 100,000 kilowatts.

Port Division

It is mainly responsible for the loading and unloading, storage, transportation and transshipment of crude oil, gasoline, kerosene, diesel, heavy oil, naphtha, liquid chemical products and general cargo. It currently has two docks with a total of five berths, a 300,000-ton offshore single-point mooring crude oil loading and unloading system, two crude oil long-distance pipelines from the Zhanjiang Station tank area and the Beishanling tank area to the Maoming Station tank area, the Beishanling crude oil depot, the Sinopec commercial reserve depot, the Zhanjiang Station crude oil depot, the port area finished oil depot and the liquid chemical product depot. 

Railway Division

It is mainly responsible for the railway transportation of the company's products leaving the factory and some raw materials, infrastructure equipment, coal and other materials entering the factory, as well as providing cargo loading and unloading transit services for local enterprises. There are currently three railway stations with a railway transportation capacity of approximately 9.6 million tons/year and a liquefied gas tank truck loading capacity of more than 600,000 tons/year.

Development History

• 1958: shale oil mining began and shale oil was produced on a trial basis in Mar 1958.
• 1963, a distillation unit with an annual capacity of 1 million tons was completed and put into operation, and the company shifted its focus from producing artificial oil to processing natural crude oil.
• May 1964: company renamed Maoming Petroleum Company of the Ministry of Petroleum Industry.
• 1974: the crude oil processing capacity reached 5 million tons/year.
• May 1975: company renamed Guangdong Maoming Petroleum Industry Corporation.
• 1976: a lubricant production system with an annual output of 150,000 tons was built, and the refinery was transformed from a fuel type to a fuel lubricant type.
• 1983: CNPC was established and the company was placed under the management of the Corporation.
• Jan 1984: company renamed China Petrochemical Corporation Maoming Petroleum Industry Company.
• Since 1990, the third set of 2.5 million tons/year distillation, three catalytic, Shuidong Port finished oil terminal and China's first and largest 250,000-ton single-point mooring crude oil loading, unloading, storage and transportation system have been built and put into operation. The company's crude oil primary processing capacity has reached 8.5 million tons/year, and its secondary processing capacity has reached 5.2 million tons/year.
• Mar 12, 1991: the State Council approved the construction of a 300,000 tons/year ethylene project.
• Jan 1992: company renamed Sinopec Maoming Petrochemical Company.
• Nov 1993: construction of the 300,000 tons/year ethylene project officially started.
• Aug 1996, the 300,000 tons/year ethylene project was completed and put into operation.
