Gas Anchor


a device for separating the free gas contained in a fluid being pumped in order to improve the pumping efficiency. It is used extensively in the petroleum industry for deep-well pumping operations in oil fields. There are seven main types of gas anchor; their operation is based on flow reversal, separating the flow into parts, amalgamation of gas bubbles, pressure gradients, and other methods.
