As global temperatures rise and weather conditions become increasingly unpredictable, the need for decisive action to reduce greenhouse gas emissions is more urgent than ever. Both businesses and governments recognize the importance of transitioning to a low-carbon economy to ensure sustainable development and the rational use of natural resources.</p> <p><strong>Aim: </strong>The aim of this study is to examine the feasibility of applying CO₂ capture technology with subsequent injection into reservoirs for storage purposes</p> <p><strong>Materials and methods:</strong> Materials from INPEX were used, taking into account actual results of CO₂ capture and storage projects in Japan. Geological and physical data on oil and gas fields located within a 100 km radius of the gas processing facility in the Atyrau region of Kazakhstan were analyzed to assess the technical feasibility of CO₂ injection. Calculations were performed using UniSim Design software, where the technological process was modeled from flue gas intake to the injection of captured CO₂ into the reservoir</p> <p><strong>Results: </strong>The technological feasibility of CO₂ capture and subsequent injection was determined, and both the capture site and the storage reservoir were selected</p> <p>Conclusion: Potential storage traps located near the developed fields of KMG were screened for CO₂ injection and storage. Regions with the highest emissions within a 100 km radius of the emission sources were evaluated. For analytical studies to determine the feasibility of CO₂ capture and storage, a gas processing facility at one of KMG’s fields in Western Kazakhstan was chosen as the emission source. This technology has not previously been applied in Kazakhstan; therefore, experience from projects in other countries, which demonstrated positive outcomes, was used as a reference</p>integrated gas treatment planthydrocarbon feedstockflue gasesCO₂ capture and storageгазды кешенді дайындау қондырғысыкөмірсутек шикізатытүтін газдарыCO₂-ні бөліп алу және жер қойнауында сақтауустановка по комплексной подготовке газауглеводородное сырьёдымовые газыулавливание и захоронение СО₂1.blogs.worldbank.org [Internet].
