At present, the environment of low oil price and high consumption tax is not conducive to the development of refining projects. CNOOC's refining business is also facing problems such as high refining cost and mismatch between upstream and downstream production and marketing. On June 15, Hou Kaifeng, general manager of CNOOC Refining and Petrochemical Co., Ltd. (hereinafter referred to as CNOOC Refining) planning department, said that based on CNOOC's refining capacity of 50 million to 60 million tons, CNOOC will turn to ethylene, aromatics, asphalt and lubricants and some downstream chemical products in the future. Continuous transformation of products. "The company's transformation from refining to chemical industry is based on CNOOC's own characteristics and market demand." Hou Kaifeng said. "The current low oil price and high consumption tax environment are not conducive to the development of refining projects. If production is carried out according to the original plan, Huizhou Petrochemical is expected to lose about 1.8 billion yuan annually." Hou Kaifeng said. The basic idea of Huizhou Petrochemical transformation is to further upgrade the aromatics reform to reduce the production of gasoline and diesel oil on the premise of ensuring adequate supply of ethylene raw materials. Huizhou Petrochemical Project accounts for nearly half of CNOOC refining capacity, and is also the only national integrated refining base. Its current capacity is 22 million tons/year for refinery, 2.2 million tons/year for ethylene and 1 million tons of PX. At present, CNOOC has 10 refining and chemical production bases. By the end of last year, its total refining capacity was 49.7 million tons/year, of which 10.3 million tons were heavy oil, 2.2 million tons/year were ethylene, 1 million tons/year were aromatics, 3 million tons/year were soda and 2 million tons/year were raw salt. "These 10 enterprises are mainly located in the Pearl River Delta, the Yangtze River Delta and the Bohai Bay Rim. They are not only close to the origin of CNOOC crude oil, but also close to the region where the market demand is the strongest." Hou Kaifeng said. He pointed out that the geographical location is an advantage of CNOOC refining and petrochemical enterprises. In addition, CNOOC took the lead in realizing the mixed ownership of various cooperation modes in domestic refining and petrochemical enterprises, which made its investment subject diversified and facilitated the transformation. Flake alkalinity is a white translucent flake solid. Flake alkali is a basic chemical raw material. It is widely used in light textile industry such as paper making, synthetic washing and soap, viscose fiber, rayon and cotton fabric, pesticide, dyestuff, rubber and chemical industry, petroleum drilling, petroleum oil refining and tar refining. And national defense industry, machinery industry, wood processing, metallurgical industry, pharmaceutical industry and urban construction. It is also used in the manufacture of chemicals, paper, soap and detergents, rayon and cellophane, bauxite to produce alumina, mercerization of textiles, water treatment and so on.
