Design and operation of gasification complex

Purpose: for gasification of liquid nitrogen to high pressure 40 P

(400 kgf/cm2)


Application: for realization of nitrogen using technologies in oil and gas production


The complex is performed using mainly domestic components and is fully adapted to Russian conditions (allows free electric power on wells required control range of performance, features of operation in north conditions, etc.).


The gasifier complex consists of pumping and processing units equipment of which is placed on two platforms KAMAZ-4318 and connected with pipelines and electric cables.


The pumping unit consists of reservoir for liquid nitrogen, pumping cryogenic system with control box,  general electropanel and two reels for electrocables. All equipment is protected by a canvass.


Technological unit consists of following main parts:

  • kettle operating on diesel fuel and equipped with an automatic control system;
  • recirculating antifreeze pump; membrane expansion tank
  • evaporator and delivery collecting canal of production nitrogen.

All equipment is placed in van, and the van is equipped with electric illumination and heaters.

Gasification complex is also equipped with pipelines of delivery of production nitrogen, coupling hoses for liquid nitrogen and ground conductor with wires.


Filling of reservoir with liquid nitrogen is produced from extraneous tank.


Gasification of liquid nitrogen is produced by circulation of hot antifreeze supplied to the evaporator from the kettle of technological unit.
