【Ten Years of Rapid Development in Chemical Engineering Equipment】752-2022: China’s First CCUS Peak-Shaving Center
Thread Content
Witnessing the decade-long rapid development of chemical processing equipment, we praise the prosperity and strength of modern China. Greater participation makes things more exciting; with you here, Haichuan becomes even better. This is just a starting point – we welcome everyone to engage more actively in discussions on this forum. Replies will be rewarded, and discussions are encouraged. ------------------------------------------------- On December 21, 2022, the relocation and reconstruction project of the Huangqiao Gas Field extraction and processing plant, a key project under Sinopec, was successfully completed and tested, marking the establishment of the first CCUS peak-shaving center in China by the East China Petroleum Bureau. Located in Huangqiao Town, Taixing, Jiangsu Province, this project is capable of sequestering 1 million tons of carbon dioxide per year. During the 14th Five-Year Plan period, it will play a key role in large-scale carbon dioxide capture, oil enhancement through carbon dioxide injection, and storage for peak-shaving purposes; it holds great significance for improving resource utilization efficiency and contributing to the achievement of the dual-carbon goals.
In 1983, the East China Petroleum Geology Bureau of the Ministry of Geology and Mines discovered the CO2 gas field during the second round of oil and gas exploration in the Huangqiao area; it is the largest CO2 gas field in China to date. To meet the development plans and environmental protection requirements of Huangqiao Town and to eliminate potential safety hazards at Sinopec East China Petroleum Bureau’s Liquefied Carbon Company, the mining and processing plant of the Huangqiao gas field has been relocated to the Xiqiao community. The construction includes a liquefaction unit, as well as auxiliary facilities such as CO2 storage systems, CO2 loading equipment, condensate storage systems, exhaust gas incineration units, and instrument air systems. Li Wenjun, deputy manager of the project department for the relocation and construction of the Huangqiao Gas Field exploitation and processing plant, said that two-thirds of the civil engineering work has been completed. The next step is to carry out industrial installations, with the entire project expected to be finished by May 30 of this year, after which it will enter the commissioning phase. After the debugging phase is completed, trial production will begin in June. It is reported that the total investment in this project is 130 million yuan. Once completed, it will become China’s first CO2 peak-shaving center with a capacity of handling 1 million tons of CO2 per year for storage. It will serve as a model for promoting the large-scale development of CCUS (carbon dioxide capture, storage, and utilization) in the country. In addition, the peak-shaving center will also achieve a \"zero\" emission target for CO2 during the CO2 sequestration process through new energy projects such as photovoltaic power generation.
In early November 2022, the relocation project of the mining and processing plant at the Huangqiao gas field of Huadong Petroleum Bureau’s Liquid Carbon Company was completed. The project commenced on September 25, 2021, and lasted for 380 days; its construction involved a carbon dioxide purification unit, as well as associated utility systems and auxiliary facilities. It is reported that the construction of the new plant is a priority project for the group company; it is of great significance for Liquide Carbon to promote the industrial development of CCUS, to build a million-ton-scale CCUS peak-shaving center in Jiangsu Province, and to make full use of the advantages associated with carbon dioxide resources.
