DKT has been committed to the research and development, engineering design and application of related technologies in the field of carbon neutralization, and has developed corresponding recovery methods for carbon dioxide and methane in various industrial gas sources (the greenhouse effect is 25 times that of carbon dioxide). CO2 miscible injection (CO2-EOR) technology is often used at home and abroad to enhance oil recovery, namely CCS-EOR,which is the most widely used and most successful method of CCUS technology abroad, but the resulting oilfield associated gas contains the concentration of CO₂ (5%~90%) fluctuates greatly, and this technology requires a large amount of CO₂ gas source. In response to this technical demand, the company has developed special adsorbents for decarbonization with high CO₂ adsorption capacity and CO₂/hydrocarbon separation coefficient, as well as supporting advanced pressure swing adsorption technology.

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