Gas Separation for ESP Operations

Overview Library

Natural gas separation occurs because of the differences in density and buoyancy between the gas and the liquid phases. A number of factors make it difficult to estimate the efficiency of natural gas separation.

Mechanical gas separators are classified as either static or dynamic. Static gas separators are designed to keep free gas from entering the pump—without applying any additional mechanical force. They provide a tortuous path that turns the fluid stream and moves it down toward the inlet ports. Some of the free gas accompanies the liquid to the intake and a portion is separated, limiting overall separation efficiency. Dynamic gas separators, on the other hand, actually impart energy to the fluid to separate the vapor from the fluid.

Vortex gas separator

Removes the free gas from the produced fluid. By venting this gas to the annulus, the separator prevents cycling, gas lock, and cavitation, resulting in a stable motor load and increased run life.
