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

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

Is a fired heat transfer equipment intended to burn fuel and to transfer the heat of combustion to a liquid without vaporising the liquid.

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 separator that is based on the difference in specific gravity for the substances to be separated.

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 heat exchanger using plates as the device for separating the two fluids and across which the energy is transferred.

A tubular heat exchanger in which a tube bundle is surrounded by a shell.

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

A vessel intended to contain fluid for storage. Typically a receiving or collecting function for further distribution. Typically with a vertical and cylindrical or square shape and a flat or conical bottom.
