Modern Status of Technology for Production of Highly Concentrated Methane by Biogas Purification

The current state of technology for obtaining highly concentrated methane by purification of biogas is an urgent problem in the context of sustainable development and reduction of greenhouse gas emissions.The study aims to investigate the methods and processes used to achieve a high degree of biogas purification with subsequent methane concentration.To achieve this objective, various techniques including the universal content analysis method, extrapolation method, systematic data analysis and comparative data analysis were used.The main results of the study show that global primary energy consumption increased by 1.4% in 2023.Meanwhile, natural gas consumption increased by 30% and renewable energy use increased by 7.1%.Studies show that biogas containing methane is highly efficient, for example in cooking (50%) and electricity generation (25%).Biogas upgrading technologies, such as chemical absorption cooling and ventilation, provide more than 98% purity of the CH4 product.The use of biogas methane instead of petrol significantly reduces emissions of harmful components such as CO, CO2 and UHC, improving air quality and reducing the negative impact on the climate.Biogas methane represents a promising energy source to contribute to sustainable energy development in the future.The practical significance of this study is that methane extracted from biogas not only has high efficiency but also reduces emissions of harmful components, improving air quality and reducing negative climate impacts.Its diverse origins, including organic waste, maximise resource efficiency, reducing methane emissions and contributing to clean energy production.Methane from biogas is highlighted as a promising energy source that plays an important role in sustainable energy development in the future.
