Know the liquid
Liquid oxygen boils at about minus 183 degrees Celsius, argon at about minus 186 and nitrogen at about minus 196. All three are stored in vacuum-insulated tanks that keep heat out, but each gas brings different safety needs.
Size for use and deliveries
Start with how much gas the plant uses per day and how often a tanker can realistically deliver. A tank sized for a few days of use with a sensible reserve avoids both frequent top-ups and paying for storage you never use.
Match the vaporiser to the peak
The vaporiser turns the liquid back into gas, so it must cope with the highest flow the plant will ever draw, not just the average. Undersized vaporisers cause icing and pressure drops at exactly the wrong moment.
Pressure and purity
Decide the delivery pressure the process needs and the purity it demands. These set the tank pressure rating, the regulators and the piping material, and a mismatch is expensive to correct after installation.
Safety points
Oxygen makes materials burn more fiercely, so equipment must be cleaned and suitable for oxygen service. Nitrogen and argon can displace the air people breathe, so ventilation and oxygen monitoring matter in enclosed spaces. Relief valves must discharge to a safe place.
Plan the site
Allow space for the tank, the tanker to reach and unload, safe distances from buildings and ignition sources, and room for a second tank later. A good layout is much cheaper than moving a tank afterwards.
