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.

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

A physical object intended to catch fluid droplets.

A drier is a physical object that is intended to remove absorbed or adsorbed liquid or water vapour below saturation state.

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 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 reboiler often boils liquid coming from the bottom of a distillation column, after which the resulting vapour is returned to the distillation column.

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

A pressure vessel located in both pump- and compressor piping systems in order to reduce residual pulsation fluctuations, as a result of discontinue operation effects, within an allowable level specified.

A distillation column intended to clean gas by washing the gas flow with water or with another liquid entering at the top of the vessel and sprayed in the gas. Typically to remove dust and small particles.

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 distillation column intended to remove light components from a fluid.

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.
