On July 27, the first ignitions of Cracker No. 1 and Cracker No. 3 in the ethylene unit of Guangxi Petrochemical’s integrated refining and chemical processing transformation project were successful, taking another solid step toward the goal of commencing operations of the facility. The drying of the ethylene cracking furnace involves removing the free water and crystalline water from the refractory materials inside the furnace. This is done to prevent cracks and detachment of the lining due to moisture in the refractory materials, which could affect the proper operation of the cracking furnace. It also serves to test the performance of various systems in the cracking furnace, ensuring smooth operation of the ethylene production facility. It is a crucial step before feeding material into the cracking furnace. The total investment in Guangxi Petrochemical’s integration and transformation project amounts to 3,045,914 million yuan. Building on Guangxi Petrochemical’s existing capacity of 10 million tons per year in oil refining, this project will involve the construction of new facilities for producing 1.2 million tons per year of ethylene and related products. Relying on the existing 30 main production units, the refining complex will build a 2 million tons per year diesel adsorption dearomatization unit and a 400,000 tons per year carbon dioxide recovery unit, while shutting down 2 of the existing main production units ； 14 new chemical processing units have been built in the chemical industry zone, including an ethylene plant with a capacity of 1.2 million tons per year, a hydroprocessing plant for pyrolysis gasoline/styrene extraction combined unit with a capacity of 550,000 tons per year, and a butadiene extraction plant with a capacity of 180,000 tons per year.
