With the increasingly severe global climate change issue, reducing greenhouse gas emissions has become a consensus of the international community. CCUS technology, as an innovative emission reduction method, can effectively reduce the concentration of carbon dioxide in the atmosphere and slow down the trend of global warming. However, the implementation of CCUS technology involves multiple links such as carbon capture, carbon compression, carbon transportation, and carbon sequestration. The technology chain is long and difficult, requiring a large amount of research and development resources to achieve technological breakthroughs and applications. 

           1、 CCUS Technology Solution of Gongda Kaiyuan

           As a company focused on chemical industrial parks and enterprise safety and environmental risk management, Gongda Kaiyuan Environmental Protection Technology (Nanjing) Co., Ltd. has achieved significant results in the field of CCUS technology. The company relies on advanced research and development platforms and rich practical experience to form a unique CCUS technology solution, including main modules such as membrane oxygen enrichment, membrane capture of CO2, and CO2 coupled waste salt to produce sodium carbonate. 

           1. Membrane based oxygen enrichment module

           This module adopts oxygen rich membrane technology, customized preparation of adjustable and stable oxygen rich air with a concentration of~35%, achieving safe coal saving and combustion assistance, thereby reducing CO2 emissions. This technology has the advantages of low oxygen production cost, modular design, small footprint, high layout flexibility, instant use, and fast oxygen production. It does not require separate safety and environmental assessment approval, providing an efficient and environmentally friendly oxygen enriched air solution for industrial combustion processes. 

           2. Membrane CO2 capture module

This module adopts high-performance membrane materials customized and produced in Germany, combined with the integrated technology of the Kaiyuan membrane process package of China University of Technology, to capture carbon dioxide in flue gas for coupling to produce green sodium carbonate. This technology has the characteristics of stable CO2 concentration, reliable performance, use of pressurized residual gas for power generation, energy recovery within the device, and recycling, achieving efficient capture and resource utilization of carbon dioxide. 

           3. CO2 coupled waste salt to sodium carbonate module

This module utilizes CO2 coupled chemical technology to react captured carbon dioxide with waste salt to produce green sodium carbonate. This technology meets the requirements of the Ministry of Industry and Information Technology's "14th Five Year Plan for Industrial Green Development" carbon peak promotion project, and has the characteristics of stable and reliable technology, mature process route, and widespread product application. Through this technology, Gongda Kaiyuan has not only achieved carbon dioxide reduction and resource utilization, but also promoted the green transformation and upgrading of related industries. 

           2、 Construction of CCUS full industry chain demonstration project

           In order to promote the widespread application and industrial development of CCUS technology, Gongda Kaiyuan actively builds the CCUS full industry chain demonstration project. The project is planned and designed according to the principles of "horizontal coupling, vertical extension, and circular linkage", achieving industrial circular combination and enterprise circular production, promoting closed-loop material circulation and full utilization between projects, enterprises, and industries, and effectively improving resource output rate. 

In terms of cooperation mode, Gongda Kaiyuan adopts the contract method of membrane process complete equipment system+technical service (MES) project, responsible for the design, manufacturing, and operation of the entire production equipment system. This cooperation model not only ensures the smooth implementation and efficient operation of the project, but also provides customers with comprehensive technical support and solutions. 

           Gongda Kaiyuan Environmental Protection Technology (Nanjing) Co., Ltd. has achieved significant results in the field of CCUS technology and made positive contributions to China's green and low-carbon development. In the future, the company will continue to increase research and development investment and technological innovation efforts, promote continuous breakthroughs and application promotion of CCUS technology, and contribute more wisdom and strength to achieving carbon peak and carbon neutrality goals.
