Gas processing is the method of removing impurities and separating valuable components from natural gas. This process typically involves the removal of water, carbon dioxide, hydrogen sulfide, and other contaminants to ensure the gas meets quality standards for transportation and use. After purification, the processed gas can be further separated into various products, such as ethane, propane, and butane. These products can be used as fuels or feedstocks in the chemical industry, making gas processing an essential step in the energy supply chain.
