The Gas treatment is the process of removing impurities and conditioning gases to make them suitable for industrial, commercial, or residential use. Natural gas, biogas, and refinery gases contain contaminants such as water, hydrogen sulfide, carbon dioxide, and heavy hydrocarbons. If not treated, these impurities can corrode pipelines, reduce combustion efficiency, and increase maintenance costs. Gas treatment methods include absorption, adsorption, dehydration, and cryogenic processes. Amine-based absorption is commonly used to remove acidic gases, while molecular sieves or silica gels remove water vapor. Gas treatment ensures that the gas meets safety standards, improves energy efficiency, and reduces environmental emissions. Treated gas is used in power generation, chemical industries, heating systems, and industrial applications. Advanced gas treatment technologies, such as membrane separation and hybrid treatment systems, have improved efficiency and reduced operational costs. Gas treatment is crucial not only for operational safety and efficiency but also for environmental protection, making it a key component in the energy and chemical industries.
