The largest carbon capture production line in the global cement industry is in China!

According to CCTV financial reports, on August 25, the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council published the Opinions on Promoting Green Low-Carbon Transition and Strengthening the Construction of the National Carbon Market. This is China's first top-level design document on carbon market planning at the central level. Xia Yingxian, director of the Department of Climate Change of the Ministry of

Ecology and Environment, said that China's carbon market construction "has made gratifying progress overall", with mandatory carbon market transactions reaching 670 million tons and 46 billion yuan in transactions, and the voluntary carbon market has registered 26 emission reduction projects, reducing emissions by 9.5 million tons. Compared with the European Union, the United Kingdom and other carbon markets, China's carbon market started later and the situation is more complex, but the achievements made so far have exceeded the expectations of international counterparts. Wang Yumeng, member of the Standing Committee of the Party Committee and deputy general manager of

China Building Materials Group, introduced the experience of the cement industry in carbon reduction. With the layout of new energy, any link in the process can achieve low emissions. The largest carbon capture production line with an annual capture of 200,000 tons in the global cement industry has been built.

It is understood that Qingzhou Zhonglian Cement Co., Ltd. has invested 283 million yuan to build a demonstration project of carbon dioxide oxy-fuel combustion coupling carbon capture with an annual output of 200000 tons. Tianjin Cement Industry Design and Research Institute and Shanghai Kaisheng Energy Conservation Engineering Technology Co., Ltd. This project is the first carbon capture and utilization project of China Building Material Group Cement, the largest cement industry in

China, the first set in Shandong Province, and has been selected as the first batch of major scientific and technological projects in the national building materials industry and the "industrial" projects of the National Development and Reform Commission in tackling key low-carbon technologies.

The project relies on the 2 # 6000t /d cement clinker production line to build a demonstration line with an annual output of 200,000 tons of CO. The main project includes oxygen production, CO self-enrichment (oxygen combustion technology), capture and purification (pressure swing adsorption + adsorption distillation technology) and other systems, which can increase the concentration of CO in flue gas from 20-30% to 75%, and then purify it to more than 99.5%, which reduces the cost by about 25% compared with the conventional chemical absorption method. The products are used in oil displacement, chemical industry and other fields.

The project started construction on July 3, 2023 and was completed and put into operation on January 12, 2024. The technical indicators of operation meet the design expectations. The successful implementation of the project not only marks a revolutionary innovation in the theory and practice of low-carbon green production process design in China's cement industry, but also contributes to China's wisdom and China's plan for carbon emission reduction and carbon neutralization in the global cement industry.

At present, the cement industry is facing the double test of energy saving, environmental protection and industrial intelligence upgrading. In order to implement the relevant policy requirements and accelerate the green low-carbon transformation and high-quality development of the cement industry, China Cement Network is scheduled for September 23-24. The 14th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference and the 6th Intelligent Summit Forum were held in Zibo, Shandong Province. This conference will bring together industry experts, enterprise representatives and many industry stakeholders to gather group wisdom and promote energy-saving, environmental protection and intelligent transformation and upgrading of the cement industry. During

the meeting, we will also organize a visit to the demonstration project of Qingzhou Zhonglian Cement Co., Ltd. with an annual output of 200000 tons of carbon dioxide oxy-fuel combustion coupled carbon capture.
