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 cooler that is intended to use air as the cooling medium.

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 process column intended to enable a distillation process.

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

A non-corrugated plate heat exchanger that has flat plates with chemically etched flow passages which are diffusion bonded together into blocks.

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

A vessel intended to enable a chemical reaction process.

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 'device' intended to separate different types of substances.

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

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 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.

A distillation column intended to withstand outside pressure.
