"This is a schematic flow diagram of a typical facility for separating and recovering liquid condensate from raw natural gas."
"Natural-gas condensate is a low-density mixture of hydrocarbon liquids that are present as gaseous components in the raw natural gas produced from many natural gas fields. It condenses out of the raw gas if the temperature is reduced to below the hydrocarbon dew point temperature of the raw gas.
The natural gas condensate is also referred to as simply condensate, or gas condensate, or sometimes natural gasoline because it contains hydrocarbons within the gasoline boiling range. Raw natural gas may come from any one of three types of gas wells:
(1) Crude oil wells - Raw natural gas that comes from crude oil wells is called associated gas. This gas can exist separate from the crude oil in the underground formation, or dissolved in the crude oil.
(2) Dry gas wells - These wells typically produce only raw natural gas that does not contain any hydrocarbon liquids. Such gas is called non-associated gas.
(3) Condensate wells - These wells produce raw natural gas along with natural gas liquid. Such gas is also non-associated gas and often referred to as wet gas." [Natural-gas condensate. Wikipedia]
