Oil & Gas


The industrial gases especially nitrogen (both liquid and gases) plays crucial role in increasing oil and gas production. The gases help in unlocking natural resources which are otherwise too difficult or too expensive to access.

Airgases Projects provides to Oil industry custom designed Nitrogen generators  based on cryogenic technology which produces high purity nitrogen. We can also provide nitrogen from PSA / membrane technology where volume of gases required is rather low and lower purity is acceptable. Our team can also offer cryogenic liquid storage, pumping and vaporisation ( SPV) systems where liquid nitrogen  is purchased from external sources . The liquid thus purchased is stored in special cryogenic storage tanks and then pumped to required pressure or directly supplied through pressurised tank and vaporised to near ambient temperature before being used by customer for its applications.

Some application examples

Nitrogen application in immiscible flood

  • High-pressure oil well gaseous injection pressured fluid  to drive gas or oil to well.
  • High pressure liquid injection to fraction rock structure below surface.

Other nitrogen applications for :

  • Air Pressure Vessels for floating offshore platforms
  • Blowout Preventer closure systems
  • Dry bulk transfer of products
  • Dry gas compressor sealing
  • Heave compensation for offshore lifting and drilling operations
  • Pipeline purging / pigging
  • Purging-of instrument panels

Airgases Projects team can assist you in deciding your requirement of nitrogen generation package for Oil & Gas application based on either cryogenic or PSA technology. Our nitrogen generation packages are not only designed for durability but are also engineered to be light weight and compact in case of offshore installations. Customer can chose between a fully automated operation by a local control system or a direct control by DCS/PLC. Rugged design and easy maintenance make our nitrogen generation package a preferred solution to guarantee trouble-free operation in any Oil & Gas environment.
