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.

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

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

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.

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.

A drum intended to separate relatively small quantities of liquid from a vapour stream.

A physical object that contains a chamber with several openings.

A pressure vessel intended for sending a pig into a pipeline.

A pressure vessel intended for receiving a pig from a pipeline.

A heat exchanger using plates as the device for separating the two fluids and across which the energy is transferred.

A non-corrugated plate heat exchanger that has flat plates with chemically etched flow passages which are diffusion bonded together into blocks.

A positive displacement pump which contains a displacing element intended to be moved in a reciprocating movement to exert pressure on a fluid, typically moving within a cylindrical space.

A positive displacement pump that consists of a chamber containing gears, cams, screws, vanes, plungers or similar elements actuated by relative rotation of the drive shaft or casing and which has no separate inlet and outlet valves.

A tubular heat exchanger in which a tube bundle is surrounded by a shell.

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

A vessel intended to contain fluid for storage. Typically a receiving or collecting function for further distribution. Typically with a vertical and cylindrical or square shape and a flat or conical bottom.
