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 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.

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

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 process column intended to enable a distillation process.

A physical object that is a long tube or hollow body intended for conduction of liquid, gaseous or finely divided solid materials, or used for structural purposes.

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 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.

An artefact where hydraulics, chemicals, electrical power and signals are distributed from the main umbilicals to different subsea systems.

A distillation column intended to withstand outside pressure.
