Nitrogen Pump

Product Details:

 ■ Nitrogen Pump Skid Heat Recovery Liquid Nitrogen Pump Skid is mainly used for assisting the hydraulic fracturing spread to mix, inject and make the liquid nitrogen fracture. The skid with the independent liquid pump and the vaporization system is equipped with liquid nitrogen tank, high pressure triplex pump, heat recovery vaporize system and auxiliary device.
Liquid nitrogen pump and vaporization system completely adopt the heat recovery system of indirectly burnt diesel engine to vaporize liquid nitrogen. All the heat for vaporizing the liquid nitrogen is acquired from the power of driving the engine.

■ The system mainly includes diesel power unit, reciprocating triplex liquid nitrogen pump, centrifugal irrigating pump, liquid nitrogen evaporator and various operation control switches.
All the heat of the pump power and evaporator is supplied by the power unit of the diesel engine. The exhaust-heat of the engine and other systems are all transformed into the useful heat for vaporizing liquid nitrogen.
In normal operating conditions, liquid nitrogen flows into the triplex pump from the storage tank through centrifugal irrigating pump (supply the inlet pressure for the triplex pump) and is pressurized to the working pressure by the reciprocating pistons, then, the high pressure liquid nitrogen flows into the evaporator and absorbs enough heat from the power unit to become high pressure gas. While the temperature of the gas reaches 60F-70F(15
-21, it will discharge through discharge valve at the flow rate of 360000 standard feet3/hour.
