Recently, in the factory area of Huarun Cement (Changjiang) Co., Ltd., at the site of the first phase of the carbon capture and utilization project, workers have been working intensively on the binding of foundation steel bars and the installation of templates. At present, the first phase of the project has completed more than 20% of the total project volume, and is expected to be completed and put into operation in February 2025.
It is understood that the first phase of the carbon capture and utilization project covers an area of about 7.4 mu, with a total construction area of about 1149.4 square meters and an investment of about 92.7 million yuan. Carbon dioxide is recovered by flue gas chemical absorption CO2 capture technology. After the completion of the project, the production capacity of liquid carbon dioxide is 60000 tons per year, of which the production of food-grade dry ice products is 6000 tons per year, and the rest is liquid carbon dioxide products. In December
2023, Liao Yueying, deputy general manager
of Huarun Cement (Changjiang) Co., Ltd., introduced that the project belongs to the large-scale CCUS demonstration project of low-concentration flue gas in the whole process, using a new type of organic amine absorbent with low energy consumption to achieve high-efficiency and low-cost capture of carbon dioxide from low-concentration coal-fired flue gas. The captured carbon dioxide will be used in carbon-rich agriculture, construction waste carbon sequestration aggregate, microalgae carbon sequestration demonstration research and methanol or olefin preparation. At the same time, cooperate with the oil field to drive and seal the remaining carbon dioxide, so as to realize the high-value utilization of carbon dioxide from waste to treasure.
At present, the project construction unit is speeding up the project construction to ensure the early completion of the project by optimizing the construction period management, implementing the fine inverted schedule strategy and extending the operation time appropriately.
