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

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

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

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

A physical object that uses centrifugal force to separate phases of different densities.

A physical object that is an assembly of pipes and piping parts, with valves and associated control equipment that is connected to the top of a wellhead and is intended for control of fluid from a well.

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

A drier is a physical object that is intended to remove absorbed or adsorbed liquid or water vapour below saturation state.

A form of suction pump; a device using a high pressure jet of water to create partial vacuum at an intake opening to draw liquid from a sump.

A physical object that is intended to deliver or exhaust volumes of vapour or gas at low differential pressure.

A separator intended to remove solids from vapour or liquid.

An arrestor which is a trap over an opening, e.g. of a ventilation system or a pipe, to prevent flames from entering the system.

A flexible vertical or near vertical pipe for the flow of liquid or gas between the seabed and the surface.

A static device generating centrifugal force from an incoming flow which separates solid or liquids from a gas of a different density.

A turbine that compresses air which is then mixed with fuel for combustion and expansion through a turbine section to generate relatively high power output for either mechanical drive or power generation.

A separator that is based on the difference in specific gravity for the substances to be separated.

A turbine in which liquid forces are driving the rotor by the reaction of acceleration of subject liquid flow in the runner while the pressure drops.

A cyclone separator intended to separate a fluid by hydraulic forces.

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 fluid conductor that consists of pipe, possibly also including pumps, valves, and control devices, intended for conveying liquids, gases, or finely divided solids.

A rigid vertical or near vertical pipe for the flow of liquid or gas between the seabed and the surface.

A physical object that is a vertical or near vertical pipe for the upward flow of liquid or gas.

A 'device' intended to separate different types of substances.

A physical object that is intended to mix fluid by means of diverging the flow with static obstacles or by increasing locally the velocity.
