Separation of produced well-stream into liquid free gas and gas free liquid can be carried out in gravity phase-separators. Separators work on the principle that the different components have different densities thereby separates when retained for some time in the separator. Different types and configurations of separators are used for different purposes. This work reviews the gravity phase separators which include their sections, internals, and classification, mode of operation as well as their design and sizing. Due to the complexity of the separators, this review will focus on horizontal gravity three – phase separators since they constitute the bulk of commercial units. The paper finally discussed the deficiencies of current models used in sizing three – phase separators and provide appropriate suggestions for improvements respectively. It is believed that once these improvements are made in three-phase separators, there will be fewer emissions during gas flaring and also a great reduction of hydrocarbons in wastewater thereby greatly reducing the cost of wastewater treatment.
