【Ten Years of Rapid Development in Chemical Engineering Equipment】2170–2025: The First 10,000-ton-scale Pilot Plant for Capturing Carbon Dioxide from Flue Gas and Using It to Produce Methanol via Hydrogenation
Thread Content
Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Regular updates and summaries are available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On January 11, 2025, the first domestic pilot plant for capturing carbon dioxide from power plant flue gas and using it to produce methanol through hydrogenation, a project undertaken by Huisheng Engineering EPCCT, successfully passed its performance tests after operating continuously for 72 hours. This achievement not only marks a decisive success in the pilot stage of this cutting-edge technology but also indicates that China has taken an important step forward in the field of carbon capture and utilization in power plants. The China Petroleum and Chemical Industry Federation organized experts to conduct on-site operation assessments. During the evaluation period, all the key performance indicators of the system met the design requirements; the average carbon dioxide capture rate was above 95%, with the highest capture rate reaching over 99% ； The conversion rates of H₂ and CO₂ are greater than 99%, and the methanol selectivity is greater than 99%. Compared with traditional coal-to-methanol processes, energy consumption is reduced by over 70%; these metrics place it at the leading level in the industry.

Huisheng Engineering received the award notice for the EPC project of Waishan Power Plant in January 2024; the project obtained approval from government authorities for environmental impact assessment in April, and field surveys began a week later. Faced with the strict deadline set by the client to begin trial operations in December, the Huisheng project team, with the support of the company, carefully planned the tasks to ensure seamless coordination between research and development, design, procurement, construction, and trial operations. Pile foundation construction was completed in May, on-site civil work started in June, installation began at the end of August, single-unit trials commenced in late November, and combined trials started at the beginning of December. After half a month of preparation, the project began trial operation on December 23. The project uses a portion of the flue gas emitted by the power plant as the feed gas, and employs chemical absorption to capture and concentrate carbon dioxide in the exhaust gases. Methanol is synthesized using an efficient hydrothermally stable catalyst that is capable of handling 100% carbon dioxide hydrogenation, while the low-grade thermal energy generated by the power plant is utilized in a hierarchical manner. Through the synergistic application of the aforementioned technologies, the project achieves carbon capture from low-concentration power plant flue gas and the synthesis of methanol from carbon dioxide through multiple technology combinations, thereby providing a replicable and sustainable technical pathway for the power industry to achieve significant reductions in carbon emissions and to produce methanol that possesses multiple functions such as those of a chemical raw material, fuel, hydrogen carrier, and energy storage medium. Shanghai Waigaoqiao Third Power Generation Co., Ltd. is a state-owned enterprise that is engaged in the cleaner utilization of coal-based power generation in the traditional thermal power sector. According to the China Industry News, Shanghai Waigaoqiao Third Power Generation Co., Ltd. utilizes multi-stage utilization of low-grade thermal energy to achieve efficient carbon dioxide capture from the flue gases of coal-fired power plant boilers for methanol production; the overall conversion rate of carbon dioxide is above 99%, the selectivity of the products is above 99%, and the comprehensive energy consumption per ton of product is less than 15 GJ ； To achieve low-cost capture of carbon dioxide from flue gases in the steel or petrochemical industries, as well as its high-value utilization, under conditions where the carbon dioxide concentration ranges from 5% to 90%; with a capture efficiency of not less than 98%, a regeneration efficiency for the capture materials of over 95%, a cost of no more than 200 yuan per ton of CO2, and energy consumption of no more than 2 GJ per ton of CO2.
