Air Products Vertical Cryogenic Storage Tank — 9,300 gal, 245 PSIG

What is the current vacuum reading, and what is the NER?

The listing does not provide vacuum level or NER (normal evaporation rate) data. Inspection was attempted but noted as incomplete, so these performance metrics may not have been captured. Request current vacuum readings and either recent NER test data or gauge trends showing daily boiloff to assess insulation integrity.

What product has it held, and what can it be converted to?

The tank was designed for LIN (liquid nitrogen) and LAR (liquid argon) service. Cryogenic tanks built for nitrogen and argon service typically can be used interchangeably for those products and sometimes for LOX (liquid oxygen), though LOX conversion requires verification of materials compatibility, cleaning to oxygen service standards, and often regulatory re-approval depending on jurisdiction.

Is the data plate legible, and is the U-1A available?

The listing does not confirm data plate condition or U-1A form availability. Given the 1977 manufacture date and incomplete inspection, verify that the nameplate is readable and request the U-1A manufacturer's data report and any subsequent U-1A rerating forms. ASME documentation is typically required for recertification and insurance.

What is involved in relocating and re-commissioning it?

Relocation requires a specialized rigging crew familiar with vacuum-jacketed vessels, as improper lifting can compromise the vacuum annulus. Re-commissioning typically involves pressure testing both inner and outer vessels, leak checking all piping and instrumentation penetrations, verifying vacuum integrity or arranging vacuum pump-down if degraded, and bringing the unit to operating temperature gradually while monitoring for anomalies. Jurisdictional inspection and revalidation of the ASME code compliance may be required depending on the receiving location.
