A physical object for storing energy, and which after discharge may be recharged.

An indirect contact heat exchanger that is intended to heat a liquid.

A dynamic pump that contains impellers provided with vanes to generate centrifugal force to achieve the required pressure head.

A gravity separator where two liquid substances separates and where the substance with the less gravity can be skimmed off.

A device that removes air or gases (methane, H2S, CO2 and others) from drilling liquids.

A physical object intended to catch fluid droplets.

A tank or vessel in which a process stream is charged or pumped and where lighter products flash off or vaporize and are drawn off at the top. The remainder heavier fractions are drawn off at the bottom of the vessel.

A static device generating centrifugal force from an incoming flow which separates solid or liquids from a gas of a different density.

A cyclone separator intended to separate a fluid by hydraulic forces.

A drum intended to separate relatively small quantities of liquid from a vapour stream.

A catcher intended to catch and separate liquid slugs from a fluid stream.
