A column in which a gas mixture is contacted with a liquid for the purpose of preferentially dissolving one or more components of the gas mixture and to provide a solution of them in the liquid.

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

A physical fluid separator that is based on the principle of attraction exhibited by the surface of a solid for a liquid or a gas when they are in contact.

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

A pressure vessel with internal packing intended to effect the main stream by introducing counter flow of a regenerative liquid or gas. Dehydration of gas by use of glycol is a typical application.

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

A physical object intended to catch fluid droplets.

A process column intended to enable a distillation process.

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 vertical vessel intended to enable chemical reactions or physical processes utilising differences in density of fluids and/or forced flow of fluid.

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

A column which transforms a material from an unstable state to a more stable state; for fluids typically by removing volatile components from a mixture.

A distillation column intended to remove light components from a fluid.

A distillation column intended to remove light components from a fluid.

A distillation column intended to withstand outside pressure.
