Liquid Nitrogen Supply Costs
However, consider the following, gas usage for a facility requiring gas on demand 24 hours per day, 7 days a week needing 70 LPM (0.07 m3/min) is equal to 36, 792,000 litres of gas per annum. This equates to 0.105 L N2/min of liquid N2 boil off requirement. Deliveries to the facility for adequate operation would mean a minimum of 63,387 L per year of liquid nitrogen to produce the boil off gaseous nitrogen to meet the facility’s nitrogen demand.
