As an inert gas, nitrogen offers a wide range of capabilities to the oil, gas and petrochemical industries. Used predominantly during plant maintenance shutdown and start-up preparations, nitrogen purging and subsequent nitrogen leak testing form a critical path to the success of any project.
Nitrogen availability for both project work and ongoing operations has therefore become critically important.
Nitrogen is available both in liquid and gaseous forms. In large quantities it is derived from ASUs and delivered via liquid nitrogen tankers. But with many oil and gas projects based in remote locations, deliveries of nitrogen to the point-of-use is a major undertaking. With the advent of low cost and reliable nitrogen gas production using air separation in the gaseous phase, many oil and gas projects have opted for in-situ nitrogen generation.
