For example, the food and beverage industry requires varying quantities of both liquid and gaseous nitrogen for food processing and packaging applications and to help maintain safe temperatures as food products are stored and transported. Nitrogen is widely applied for heat treatment processes in metal fabrication and automotive industries under ALNAT brand. Laser applications need nitrogen in order to provide metal cutting by laser-machines. Pharmaceuticals and biotechnology industry consumes nitrogen for temperature control and freezing with stringent quality and regulatory requirements. Refineries and petrochemical plants require large volumes of gaseous nitrogen to purge oxygen and moisture during blanketing operations.
