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 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.

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 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 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 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.
