Petroleum Refining


The petroleum refining industry consumes significant amount of nitrogen as well as oxygen and hydrogen for some applications. Airgases Projects can provide to the refineries custom designed Nitrogen generators and Air Separation Plant based on cryogenic technology which produces high purity nitrogen and oxygen required for various applications. We can also offer hydrogen recovery plants from off gas through PSA technology. Our capabilities also includes providing low purity oxygen plants based on VPSA technology and nitrogen from PSA technology where volume of gases required is rather low and relatively lower purity products are acceptable. In addition our team can offer cryogenic liquid storage, pumping and vaporisation (SPV) systems where liquid oxygen and 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 inerting and purging

  • Storage tanks containing combustible liquids
  • Process equipment during shutdown and start up
  • Tankers during filling and emptying while at port
  • Discharging the stone dust in oil and natural gas drilling
  • Drying  technical equipment during idle time, following restart and after repairs

Oxygen application for combustion and chemical oxidation

  • Generating synthesis gases through partial oxidation or gasification
  • debottleneck Clause Plant
  • faster regeneration catalyst in FCCU

Hydrogen application for treating of petroleum products

  • Hydro treating petroleum products
