Gas purification is the process of removing impurities and contaminants from gases to improve their quality and safety. This is essential in various industries, including chemical manufacturing, oil and gas, and environmental protection. Common methods of gas purification include adsorption, absorption, and filtration, which help eliminate harmful substances like sulfur compounds and volatile organic compounds. The purified gas can then be used for different applications, such as energy production, industrial processes, or even in the production of medical gases. Effective gas purification not only enhances product quality but also helps in meeting regulatory standards and reducing environmental impact.
