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

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

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

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

A physical object intended to catch fluid droplets.

An internal combustion engine in which ignition of the fuel injected into the cylinder is performed by the heat of compression of the air charge.

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

An electric motor for operation by direct current.

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

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

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.

An internal combustion engine that is a reciprocating engine in which gaseous fuel is mixed with air to form a combustible mixture in a cylinder which is fired by spark ignition.

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 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.
