Jiangsu Zhongchuang Qingyuan Technology Co., Ltd. is a comprehensive environmental protection high-tech enterprise invested and constructed by Tsinghua University to implement the national "double-venture strategy", which integrates R & D, design, manufacturing and technical services.
In recent years, it has won many honorary qualifications, such as national specialized, special and new small giant enterprises, national post-doctoral research workstations, and national high-tech enterprises. Its technological achievements have won the first prize of the National Science and Technology Progress Award in 2020, which is the only first prize in the field of air pollution control in the 21st century. Up to now, the company has established a sound intellectual property system, with a total of 39 patents, 31 authorizations and 8 invention patents, many of which have been transformed into achievements, and achieved self-control in the field of key material research and development.
With excellent scientific and technological research and development strength, the research team of Tsinghua University has developed a series of key technologies for efficient carbon capture and deep purification of pollutants from coal-fired flue gas. In terms of core materials for carbon capture, the team has successfully developed a highly stable compound amine absorbent system (ZCQY300) suitable for coal-fired flue gas, which has more than doubled the cycle load compared with MEA and reduced the average degradation rate by 50%. Based on the above results, the team further developed a low energy consumption ternary two-phase carbon capture absorbent (ZCQY400) composed of compound amine-physical solvent-water, which uses centrifugal enhanced high-efficiency dynamic phase separation technology to reduce regeneration heat consumption by more than 40%. In terms of
core technology research, the team has successfully developed a desorption catalytic material with porous structure, which significantly improves the reaction rate of absorbent regeneration. The measured results show that catalytic desorption can reduce the cost of carbon capture by about 10.5%. Aiming at the problem of regeneration and purification of absorbent, the team developed the technology of ion resin adsorption coupled with pressure swing distillation purification equipment, which realized the efficient regeneration of degraded and deactivated absorbent, with the removal rate of heat stable sa < the recovery rate of solvent exceeded 80%; Aiming at the problem of volatile escape of organic components in absorbent, a multi-stage water washing coupling amine concentration and recovery equipment was developed, which realized the efficient control and recovery of amine escape, and the flue gas emission reached the level of ultra-low emission. In addition, the team pioneered the multi-stage parallel heating reboiling technology of large-size desorption tower to achieve efficient and stable operation of desorption tower, while further reducing the overall energy consumption of the system, providing key support for the large-scale promotion of carbon capture technology.
As a key demonstration project of the National Engineering Research Center for Cooperative Control of Air Pollutants and Greenhouse Gases, Hebei Jiantao Coal-fired Boiler Flue Gas Carbon Capture Cooperative Deep Treatment Project opens a new paradigm for the industry with innovative technology. Based on the deep treatment of flue gas pollution from coal-fired boilers in the park, this project carries out carbon capture of total flue gas, with a capture rate of ≥ 90%, an annual capture of 200,000 tons of CO2 , and a purity of CO2 > 99.8%. It is directly used as raw material for acetic acid production in Jiantao Park. This mode eliminates the energy consumption of the original purchased liquid CO2 gasification process equipment, and at the same time reduces the emission pollution caused by the heavy duty truck circulation transportation of nearly 4000 vehicles per year. It is estimated that the amount of CO2 recovered by the project is equivalent to the total amount of CO2 absorbed by nearly 10000 mu of forest planted around Xingtai in one year. Since it was put into operation, the project has been running stably for more than 4500 hours, and the key technical indicators are excellent: regeneration heat consumption ≈ 2.2 GJ/t CO2 , solvent loss & lt; 0.3 kg/t CO2 . This project can efficiently capture CO2 without secondary pollution, and can further remove SO2 , particulate matter and other gaseous pollutants. The emission values of sulfur, dust and nitrate are far below the national ultra-low emission standards. To achieve near-zero emission of boiler flue gas pollutants, it provides a replicable and popularizable demonstration model for the coordinated treatment of pollution reduction and carbon reduction in this field.
In order to accelerate the realization of the "double carbon target" and actively promote the green and high-quality development of the industry, China Cement Network will hold the "2025 China Cement Double Carbon Conference and the 13th Energy Conservation and Environmental Protection Technology Exchange Conference" on May 27-28, 2025. At the same time, the release ceremony of "2025 ESG Ranking List of Cement Industry" was held . This conference will bring together industry elites and multi-resources to provide all-round support for the industry in terms of technology, policy landing and resource docking.
