Nitrogen is widely used in Oil & Gas Industries. Since it is an inert gas, it can prevent corrosion and explosions. At high pressures, Nitrogen is used for enhanced oil recovery and at relatively low pressure is used for line purging and tank blanketing. It is also being used in unit laboratories and welding processes. Onsite nitrogen generators are the economical option for most oil and gas nitrogen needs which require 95-99.999% purity.
In the coal industry, nitrogen is either injected continuously into the mine to displace the oxygen in the mine or to extinguish fires. To extinguish a fire, the oxygen level of the gases should be less than LEL (lower limit of explosion). Having a reliable onsite nitrogen generator, nitrogen can be produced in a cost-effective process whenever is needed without concerns with liquid delivery.
