Daqing Hongwei Qinghua Petrochemical Co., Ltd.

Daqing Hongwei Qinghua Petrochemical Co., Ltd. (shortened as Daqing Hongwei Qinghua Company) was established on November 20, 2012, located in the Hongwei Chemical Industrial Park of Daqing High-tech Zone. The company currently has 361 employees, occupies an area of 13.62 hectares, with a registered capital of 400 million yuan. It is solely funded and independently operated by the State-owned Assets Operation Company of Daqing High-tech Zone. The main business includes the production, operation, and sales of chemical products. The 150,000 tons/year propylene project invested and constructed by the company was mainly designed by East China Design Institute, and the main construction was carried out by CNPC Seventh Construction, Eleventh Chemical Construction, and Oilfield Chemical Construction. The total investment for the construction was 1.442 billion yuan. The project consists of three main units: a 500,000 tons/year TMP unit, a 450,000 tons/year gas fractionation unit, and a 140,000 tons/year MTBE unit, along with supporting facilities. The primary raw materials are residue oil, wax oil, and mixed butenes, used to produce propylene, MTBE, propane, gasoline blending components, diesel blending components, and liquefied gas. The 150,000 tons/year propylene project is scientifically designed, reasonably laid out, and technologically advanced. The reaction section of the TMP unit adopts a two-stage riser technology patented by China University of Petroleum for increasing propylene yield, maintaining good quality of gasoline and diesel while effectively reducing the yields of dry gas and coke. The regeneration part uses a high-efficiency regeneration technology of the coke burning tank, which not only recovers and protects the activity of the catalyst but also significantly improves the yield and quality of the products. The unique features of the coke burning tank, such as high coking efficiency and low pressure drop, lay a solid foundation for the optimized operation of the facility. The 150,000 tons/year propylene project started construction in May 2013, under the strong support of the Daqing High-tech Zone. After more than one year of construction, it has been put into normal production, expected to achieve an annual sales revenue of 4.6 billion yuan, making due contributions to promoting the development of the local petrochemical industry.
