Combo N2 and Fluid Pump Unit imageClick on + for more info.

NITROGEN PUMPING SYSTEM EQUIPMENT DESCRIPTION

The combo unit will be fabricated on a trailer. The completed unit will consist of two separate systems with the operation console in the center.

The nitrogen pumping system will consist of the following engine, hydraulic system, liquid nitrogen triplex pump, nitrogen boost pump, water bath vaporizer, after cooler heating system, hydraulic heating system, coolant circulating pump, and all valves, and controls for normal operations

NITROGEN PUMPING SYSTEM PRINCIPLES OF OPERATION

The liquid nitrogen is delivered from the tank to the triplex high pressure pump by a centrifugal. The liquid nitrogen is pumped through a water bath vaporizer where the liquid is converted into a gas at 70º F plus. It then passes through a high pressure discharge line to leave the unit and go down hole. The nitrogen is converted from liquid up to 180º F by using heat generated from the hydraulic system, engine coolant system, and engine exhaust system.
