Nitrogen fire-fighting units
Nitrogen fire-fighting units are designed for extinguishing fires caused by inflammation of various flammable substances which can only burn in the presence of air, such as oil, oil products, or gas condensate, in enclosed volumes and premises, as well as for the prevention of fire and explosion hazardous situations at oil and gas producing enterprises.
The operating principle of a nitrogen fire-fighting unit is based on inert properties of the resulting air mixture with 95–99% nitrogen concentration. With this level of nitrogen concentration, burning process is rendered impossible. Gaseous nitrogen produced by membrane gas separation unit of a nitrogen fire-fighting unit is forced into a receiver which capacity is calculated based on the volumes of premises and vessels to be fire-protected by the unit.
In case of fire, nitrogen delivery into the fire-affected volume starts automatically. This ensures quick and reliable fire extinguishing without damaging equipment or injuring personnel. Furthermore, nitrogen fire-fighting unit is designed so as to allow the use of nitrogen generated for purging process vessels simultaneously with automatic replenishing of its reserves.
Nitrogen fire fighting has a number of objective advantages associated with the unit structural simplicity, serviceability, and high cost-effectiveness.
