The extracted wet oil is a mixture of crude oil, natural gas, salt water and contaminants. In order to reach the required quality for further processing in a refinery, the mixture needs to run through a purification phase. The purification takes place in special separation plants in several processing stages. During the first step of the purification, natural gas is extracted from the oil, followed by a separation of crude oil and salt water.
