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

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 generator for the production of alternating current and voltage.

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

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

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

A device that removes air or gases (methane, H2S, CO2 and others) from drilling liquids.

A physical object intended to catch fluid droplets.

An electric generator for the production of direct current and voltage.

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.

An energy transducer that transforms non-electric energy into electric energy.

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 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 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 physical object that is a casing with an arrangement of two or more gear-wheels transmitting rotating motion from the input shaft to the output shaft.

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.
