At present, this technology has been successfully applied to the CO₂ flooding and storage projects of two oilfield companies of PetroChina, realizing the large-scale industrial demonstration application of CCUS technology in China. In 2021, it was featured by CCTV-13, the news channel of China Central Television. Through efficient and low-cost carbon capture, utilization and storage, it has established an important demonstration for the project area to achieve the carbon emissions peaking and carbon neutrality as soon as possible.

Technical features and advantages:

- Advanced and proven technology, and simple process flow;

- High adsorption capacity and CO₂/hydrocarbon separation coefficient of the special CO₂ adsorbent;

- Fully adapt to the large fluctuation (5-90%) of CO₂concentration in feed gas;

- High purity and recovery of product CO₂, and high recovery of hydrocarbon;

- Highly integrated and automated plant;

- The separation and recovery cost of CO₂ and hydrocarbon is low, and the economic and ecological benefits are high;

- The whole separation process has no secondary pollution and is green and environmentally friendly.

Application:

- Separation and recycling of CO₂ in CCS-EOR process;

- CO₂ separation in biogas, landfill gas, etc.
