Peng Guangqin, deputy general manager of the company, said that the refining and chemical integration project can produce 14 million tonnes of chemicals with 20 million tonnes of crude oil.
By applying the ebullating bed resid hydrocracking technology, the project will increase the utilization rate of crude oil by 5 percent, Peng added.
The project is also able to produce 4.5 million tonnes of aromatics per year, raising China's total output of aromatics by 30 percent, which will make up for the shortage of domestic supply.
By using seawater to replace industrial cooling towers and other comprehensive utilization of resources, the project will save up to 1.2 million tonnes of standard coal and 40 million tonnes of fresh water every year.
The full operation of the Hengli complex will contribute to the long-term transformation and upgrading of the petrochemical industrial structure and boost the local economy, said Cai Ronghua, a National Development and Reform Commission official.
As one of the pillar industries of Dalian, the largest port city in northeastern China, the city's petrochemical industry recorded an output of around 200 billion yuan (28.9 billion U.S. dollars) in 2018.
