The chemical industry has seen significant development over the past decade; let’s praise the prosperity and strength of modern China. By contributing our ideas, we can foster more active participation from everyone. HaiChuan becomes even better with your involvement – we welcome everyone to take part in discussions on this forum. Everyone should prioritize safety and know how to handle emergencies. *********************************************Xinjiang Guanghui Carbon Technology Comprehensive Utilization Co., Ltd. plans to build a carbon dioxide capture facility with an annual capacity of 3 million tons. The first phase will involve a pilot project with a capacity of 100,000 tons per year, while the second phase will have an annual capacity of 3 million tons. The total investment for the first phase of the project is 80.13 million yuan. The main units include compression, liquefaction, cryogenic distillation, storage, and loading facilities. Construction of the project began in April 2022; mechanical installation was completed on March 11, 2023, trial operation started on March 17, and qualified products were produced on March 25. At present, the plant produces around 100 tons of liquid carbon dioxide per day. In the future, the company will gradually optimize the system’s operation to increase its capacity, with the goal of achieving an output of approximately 300 tons per day. In April 2023, the launch ceremony for the products was held for Hami’s first CCUS (Carbon Dioxide Capture, Utilization and Storage) demonstration project – the 100,000 t/a carbon dioxide capture and utilization demonstration project operated by Xinjiang Guanghui Carbon Technology Comprehensive Utilization Co., Ltd. in the Yiwu Industrial Park. This not only marks the official entry of the enterprise into the operational phase, but also signifies further expansion of the Hami coal chemical industry chain as well as a new level of green, sustainable, and high-quality development. This project adopts a low-cost carbon capture technology based on \"ammonia refrigeration + low-temperature liquefaction distillation\". Through processes such as compression, purification, and low-temperature liquefaction distillation, it produces liquid carbon dioxide products. It overcomes various technical challenges, including the deep desulfurization of feed gas and the recovery and regeneration of non-condensable gases. As a demonstration project for CCUS, it offers multiple benefits in terms of research, economics, and society. It is understood that the project uses the exhaust gas from the low-temperature methanol washing unit of Xinjiang Guanghui New Energy Co., Ltd.’s 1.2 million tons per year coal-to-methanol plant, which also produces 700 million cubic meters of LNG, as raw material for the production of liquid carbon dioxide. This liquid carbon dioxide is then used to enhance oil extraction in the Santanghu oilfield area, replacing the existing water flooding method; this approach can effectively improve the efficiency of oil extraction while also contributing to water conservation and environmental protection.
