Rich gas is a gas containing more carbon 4 and carbon 5; dry gas is a gas containing more carbon 1 and carbon 2; liquefied gas is gas that has been liquefied under pressure
Natural gas associated with oil fields, after undergoing dehydration, purification, and light hydrocarbon recovery processes to yield liquefied gas and light oils, is referred to as dry gas when its main component is methane. Generally, natural gas with a methane content of over 90% is called dry gas. Gas with a methane content of less than 90%, and an alkane content such as that of ethane and propane of over 10%, is called wet gas. Natural gas is classified into lean gas and rich gas depending on its composition; lean gas contains a high proportion of methane, while rich gas has high levels of ethane, propane, and butane. Liquefied gas is composed of C3, C4, and C5 compounds
