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.

An electric motor driven by alternating electric current.

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 conveyor that consists of a suitably tensioned endless belt made from hard wearing materials and arranged to run over rollers.

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 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 protective device used to protect equipment (e.g. riser pipes and submerged pumps) against environmental exposure.

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 mechanical cable that consist of series of interconnected links forming a flexible cable, used for sustaining a tensile load.

A conveyor in which endless chains are used to support slats, apron, pans, buckets, as distinct from the use of single band.

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 device compensating for axial or radial movement between two elements that is connected.

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.
