The company has 21 sets of refining and chemical production units including two sets of atmospheric and vacuum pressure, two sets of catalytic cracking, delayed coking, catalytic reforming, hydrogenation, hydrogen production, and polypropylene. The crude oil processing capacity reaches 5 million tons/year, and the polypropylene production capacity is 100,000 tons/year. The company produces more than 60 petrochemical products such as gasoline, diesel, naphtha, benzene, liquefied gas, solvent oil, polypropylene, etc. 17 products have been awarded the title of high-quality products at the provincial or ministerial level or above, among which the export of light diesel and 6# pump The extraction solvent oil won the National Gold Award, and the petroleum toluene, xylene and 120# solvent oil products won the National Silver Award. Entering the "Eleventh Five-Year Plan", Changlian is standing at a new historical starting point. The crude oil inferiority and oil quality upgrading and transformation project was successfully laid on October 18, 2008, and has entered the comprehensive construction stage. The total investment in the project is about 5.7 billion yuan, and it is planned to complete and put into operation an 8 million tons/year oil refining and processing production line in June 2011. The main purpose of the construction of this project is to meet the supply of refined oil products in Hunan Province and surrounding markets. It is based on the premise of saving project construction investment and land use. It fully relies on the existing conditions and device characteristics of Changling and adopts new technologies and new processes to achieve large-scale crude oil processing. , equipment enlargement, production process and product quality cleanliness. This project will build 7 new units and reuse 10 existing units. After the project is completed, its rich resources can provide guarantee for the extension of subsequent industries, which is bound to promote the sound and rapid development of Hunan's local economy. After the "refining and chemical integration" project reaches production, Changling Branch is expected to achieve sales revenue of more than 50 billion yuan and pay taxes of more than 7 billion yuan.
