Nitrogen Pumping Units

An oilfield Nitrogen pumping unit is a highly sophisticated device which performs several simultaneous functions in order to convert liquid Nitrogen to a gas.

Firstly the Nitrogen unit is fed with liquid Nitrogen at a temperature of –196oC. It then pumps the liquid Nitrogen at this temperature to pressures of up to 15,000 psi before it supplies heat to transform the liquid Nitrogen into a gaseous phase.

All the necessary power to perform the above operation is supplied by a diesel engine, while a sophisticated heat recovery system supplies the required thermal power.
