2024: A year of blooming flowers and joy on the forum **********************【Ten Years of Progress in Chemical Processing Equipment】Ongoing updates and summaries available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Industry Forum Website) ***************** On April 8th, it was reported that the low-energy consumption pressure swing adsorption carbon capture pilot plant, developed by CPECC’s Southwest Branch in collaboration with other organizations such as the Southwest Oil and Gas Field, has been put into operation. This marks the successful deployment of China’s first low-energy consumption, ultra-low pressure (80 kPa) pressure swing adsorption carbon capture system for use in the natural gas purification industry. 　　Carbon dioxide capture, utilization, and storage (CCUS) is a technology that separates carbon dioxide from industrial exhaust gases, flue gases, or the atmosphere, either for direct use such as in oil enhancement, or by injecting it into geological formations to achieve permanent reduction of carbon dioxide emissions. This set of equipment is primarily used to capture the exhaust gas at the top of the absorption tower in the exhaust gas treatment unit of natural gas purification plants. After treatment by the device, the carbon dioxide capture rate reached 95.72%, and the purity of carbon dioxide in the desorbed gas reached 95%. 　　In recent years, leveraging its strengths in the fields of \"natural gas+\" and clean energy, the Southwest Branch has carried out research on carbon capture technologies such as chemical absorption-based carbon capture and pressure swing adsorption-based carbon capture, as well as on energy-saving optimization techniques that integrate processes, equipment, and solvents. As a result, it has developed 14 patented technologies, including high and medium pressure natural gas chemical absorption-based carbon capture technologies, low pressure flue gas or exhaust gas chemical absorption-based carbon capture technologies, and low pressure flue gas or exhaust gas pressure swing adsorption-based carbon capture technologies, along with a series of highly efficient patented solvents.
