In recent years, the toxic fumes generated by explosives have been a concern for blasters, explosive manufacturers, and mining companies. In the Western United States, blasters have been seeking ways to control the generation of nitrogen dioxide, a very toxic gas that can be produced by large blasts at surface coal mines.
This can apply to any work area, including a manufacturing plant, heat-treating facility, offshore oil and gas platform, oilfield, chemical facility, or other mining operation.

The main purpose of a cryogenic nitrogen plant is to provide a customer with high purity gaseous nitrogen (GAN). In addition liquid nitrogen (LIN) is produced simultaneously and is typically 10% of the gas production. High purity liquid nitrogen produced by cryogenic plants is stored in a local tank and used as a strategic reserve.
