LCO2 Tank

The United States Air Force is conducting market research for a liquid CO2 storage tank. The tank should have a capacity of 6,000 - 7,000 liters and be a vacuum-insulated double wall tank consisting of two concentric vessels. The tank must be manufactured and tested in accordance with EU 97/23/EC and EN 13458. The company's Quality Management System must satisfy all elements of the EN ISO 9001/2000 program or ASME (U, U2, R-Stamp). Key features of the tank include: • A low-temperature resistant austenitic steel inner tank and an outer tank made of carbon steel with an anti-corrosion primer and a top coat of paint • The interspace between the two tanks filled with perlite insulating powder and an absorbent to maintain a vacuum pressure of < 0.05 millibar during tank operation • A maximum allowable working pressure for the inner vessel of 22 bar gauge for temperatures ranging from -196°C up to 20°C • A safety valve system to prevent overpressurization and a safety shutoff valve • The ability to supply pressurized LCO2 at 189-261 psi (13-18 bar) to a Dry Ice Production Hub through a flexible hose attachment
