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 propeller like device with agitational or rotational movement located in a tank to prevent the content of the tank to build component segments.

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

Is an artefact intended to retrieve a material at a particular location and inserted into something so as to test its conditions.

A dynamic compressor in which the gas is accelerated by the action of a bladed rotor and where the main flow is along the rotation axis of the rotor.

A ball valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

A rotary valve that has a ball closure member.

A valve that has one seat which provides a seal, and a bleeder line and valve that are tapped into the block valve's bonnet.

A valve that can be used for rapid depressurizing of a high pressure system.

A physical object intended to compress and supply air or gas at medium pressure and medium volume flow.

A butterfly valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

A rotary valve that has a closure member of a disc type with a shaft parallel, or near parallel, to the plane of the disc, with an axis of rotation transverse to the flow direction.

A dynamic compressor in which one ore more impellers accelerate the gas and where the main flow through the impeller is radial.

A dynamic pump that contains impellers provided with vanes to generate centrifugal force to achieve the required pressure head.

A valve that permits fluid to flow in one direction only.

A choke valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

A valve that can be used to obstruct the fluid passing inside, and has the ability to reduce the pressure from the inlet port to the outlet port.

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

A physical object that is driven by a prime mover by which energy is either constantly or periodically added to an amount of gas in order to increase its pressure.

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 valve that can be used to modify (regulate) the fluid flow rate in a process control system. It usually includes an actuator, which responds to a signal from the controlling system and changes the position of the flow controlling element in the valve.

A pressure relief valve that has its closing force provided by a spring.

An element located in a flowstream using the Coriolis principle to measure the flow.
