Definition - What does Separator Units mean?
Separator Units, also known as Oil and Gas Separators, are large pressure vessels used to separate well fluids into liquids and gaseous components. The separator units are also used in petroleum production to separate the production fluids into gas, oil and water. They are capable of separating the three components while working on a principle to unsure that they have different densities. This principle allows the separators to arrange the components with water at the bottom, oil in the middle and gas on top.
Petropedia explains Separator Units
A separator unit is designed in a manner that it works on a principle to ensure that the components have different densities. With this principle, the liquid leaves the separator at the bottom via a dump-valve or level-control, and the gas leaves the separator at the top that passes through a mist extractor removing all the liquid droplets.
Separators are categorized based on their operating pressure. High-pressure units can handle pressures from around 975 to 1500 psi. Low-pressure units are capable of handling pressures from 10 to 180 psi. The separation degree between liquid and gas depends on the residence time of the fluid, the separator operating pressure and type of flow of the fluids. Lamina flow allows less bubbles to escape as compared to Turbulent flow.
