Mechanical completion worker/source of China Salt Red Sifang carbon dioxide emission reduction and joint alkali technical transformation project: gasification world date: 2023-05-09 Click rate: 30 Recently, the carbon dioxide emission reduction and energy-saving and environmental protection technical transformation project of the joint alkali device of China Salt Anhui Red Sifang Co., Ltd. (referred to as "China Salt Red Sifang"), which was undertaken by China National Chemical Engineering No. 3 Construction Co., Ltd., recently achieved mechanical completion. Currently, the project has entered the commissioning stage. The China Salt Red Sifang carbon dioxide emission reduction and joint alkali unit energy-saving and environmental protection technical transformation project uses excess carbon dioxide from the ethylene glycol unit and excess liquid ammonia from the synthetic ammonia unit to produce soda ash. Use energy-saving and environmentally friendly equipment and technologies such as vacuum belt alkali filters and exhaust gas absorption towers to transform the original soda ash plant ； A heated fluidized bed dry ammonium furnace was selected to transform the original wet ammonium device. After the technical transformation of the project, it is possible to turn carbon dioxide into waste, reduce greenhouse gas emissions, and further reduce the comprehensive energy consumption of soda ash. It is of great significance for ensuring environmental quality, leading green production, and assisting in emission reduction and carbon reduction. Project OverviewConstruction Project Name: Carbon dioxide emission reduction and energy-saving and environmental protection technical transformation project of joint alkali device ； construction site: Within the joint alkali production area of Zhongyan Anhui Red Sifang Co., Ltd., Hefei Circular Economy Demonstration Park ； Construction content: The total investment in project construction is approximately 208.34 million yuan. Main construction contents of the project: The project covers an area of 8.04 acres. It uses excess carbon dioxide from the ethylene glycol unit and excess liquid ammonia from the synthetic ammonia unit to produce soda ash. It uses energy-saving and environmentally friendly equipment and technologies such as vacuum belt alkali filters, powdered liquid alkali, dilute liquid distillation, and tail gas absorption towers to transform the original soda ash unit. It also uses a heated fluidized bed dry ammonium furnace to transform the original wet ammonium unit. New equipment such as carbonization tower, vacuum belt filter, light liquid distillation tower, dense gas compressor, light ash steam calciner, crystallizer, fluidized bed dryer, screw ammonia compressor, etc. have been added. After the technical transformation and expansion of the project, it can add 150,000 tons/year of light soda ash, 150,000 tons/year of wet ammonium, and 200,000 tons/year of dry ammonium.
