Gas separators are devices used to separate two or more gases from a mixture of gases. They are used in a variety of industries, including oil and gas, chemical, and power generation. Gas separators work by using a combination of physical and chemical processes to separate the gases. The most common type of gas separator is a membrane separator, which uses a membrane to separate the gases. Other types of gas separators include adsorption separators, coalescing separators, and centrifugal separators.
