Nitrogen services

Nitrogen is a colourless, odourless, tasteless and inert gas under standard conditions. Nitrogen is a constituent element of all living tissues and amino acids. Many industrially important compounds − such as ammonia, nitric acid, and cyanides, contain nitrogen.

PRS Helium Leaktesting Services

Uncontrolled emissions, the loss of containment and the release of hazardous petrochemicals pose an immediate danger to Health, Safety and the Environment. Experience has shown that leaks do occur − mostly during plant start-ups − after new facilities have been commissioned or after maintenance has been performed on existing facilities.

Nitrogen Purging, Drying & Product Displacements

The hydrocarbon processing industry often processes hazardous products that must be removed from the facilities before any maintenance or cleaning work can be carried out. Systems are drained of fluids and any remaining gases are purged using Nitrogen.
