The refinery will be occupying approximately 260 hectares of the island.
The refinery will also be initially producing 500,000 tons of benzene, which will be used as feed stock for the production of 1.5 million tons of paraxylene (PX), according to the company.
"The 1.5 million tons PX facility will be the world's largest single-lined production unit.
In the future, with the production of PX and benzene it will solve the urgent shortage of raw material problem of the Hengyi downstream unit in China, Hengyi said.
The investment for Phase 1 of the Hengyi project is expected to amount to some 4 billion US dollars, creating about 780 job opportunities, according to a story published in "Global Times", Beijing.
The production of paraxylene will be doubled during Phase 2 of the project, the company said.
"The second phase aims to duplicate a series of refinery and aromatic plants on the northern side of the Phase 1 site.
"After completion of the second phase, the plant will be the world's largest PX production base.
Benzene production, meanwhile, is seen to be in excess of one million metric tons once Phase 2 is under way.
Meanwhile, the plant will also produce 2.05 million tons of gasoline and diesel to fulfill local demand.
Originally, Hengyi Industries was supposed to build a co-generation plant to improve the energy efficiency of the project, but this will now be undertaken by the Energy Department under the Prime Minister's Office (EDPMO).
The power plant is expected to produce 625 tons of steam for 100 megawatts of electricity which will be used by the complex.
There will also be a water treatment plant to recycle the waste water on the site.
According to the corporate video, oily and salty waste water will undergo intensive treatment so that they can be reused. Sanitary and contaminated rain water will also pass through the treatment plant for recycling.
For the first phase of operations, the desalination plant will produce 50,000 tons of fresh water for the site.
PMB will be divided into two sections.
The eastern section will "eventually be building five jetties capable of exporting 50,000 tons of petrochemical products, while the western side will have three blocks of 50,000 tones of crude oil and bulk petrochemical jetties.
According to the presentation video, most of the crude oil will be supplied by Brunei and the first phase of the refinery integrated aromatics project is expected to use eight million tons of crude oil and condensate as the major feed stocks.
