【Ten Years of Great Progress in Chemical Technology】037-2020: China’s first flue gas carbon dioxide capture and purification unit for thermal power plants was successfully put into operation

Thread Content

Ten years of rapid development in chemical processing equipment – praise for China’s prosperity and strength. This is just a starting point; more participation will make things even more lively. HaiChuan becomes even better with you all here; we welcome everyone to engage more in discussions on this forum. Happy May Day! A safe and secure Red May ********************************************* The boiler flue gas carbon dioxide capture and nitrogen production project carried out by Dongying Gangcheng Thermal Power Co., Ltd. utilized the industrialization technology for flue gas carbon dioxide capture and purification developed by Dalian University of Technology. The engineering design was undertaken by Dalian Chemical Engineering Design Institute Co., Ltd. It took 17 months to complete the design, construction, and commissioning of the project; successful operation began on January 16, 2020. On that day, the first batch of liquid carbon dioxide was captured and stored in tanks, with a purity of over 99.9%, exceeding the standards for industrial-grade carbon dioxide. At the same time, nitrogen gas with a purity of 99.9% was also produced. The successful commissioning of the boiler flue gas carbon dioxide capture and nitrogen production project by Dongying Gangcheng Thermal Power Co., Ltd. (capacity: 85,000 tons of liquid carbon dioxide per year, 10,000 Nm3/h of nitrogen) demonstrates that, in addition to having the capability to design systems for carbon dioxide capture from flue gases, our institute is able to adapt such designs to meet the specific requirements of various projects. In this project, we not only produced liquid carbon dioxide from waste gases but also generated high-quality nitrogen, thus turning waste into valuable resources. Our institute will maintain close cooperation with Dalian University of Technology, continuously advancing innovation in flue gas capture and purification technologies, to make greater contributions to global environmental protection.
