CCH Custom Build 74K LP-H-SS — 51,800 gal 700 PSIG High-Pressure Vaporizer

Is this sized for my peak demand or my average?

High-pressure vaporizers are typically sized for peak hourly demand, not average flow, because LNG send-out requirements are driven by maximum concurrent equipment load. This unit's 51,800-gallon capacity translates to a specific vaporization rate that depends on heat input and operating conditions not detailed in this listing. Ask the seller for the rated vaporization capacity in standard cubic feet per hour or gallons per minute at your inlet pressure and temperature.

What gases can it be put into service with, given what it ran before?

This unit was designed for LNG service and carries stainless steel lining appropriate for cryogenic temperatures. LNG service history means the vessel handled methane and trace heavier hydrocarbons; it can generally remain in natural gas/methane service or similar clean hydrocarbon duty. Any change to a different cryogenic fluid or corrosive service would require engineering review of material compatibility and likely requalification under the applicable code.

What are the installation and utility requirements?

High-pressure vaporizers require a foundation capable of supporting the vessel's operating weight, liquid and vapor piping rated to 700 PSIG minimum, and either ambient air circulation or a heat source depending on vaporizer type. This listing does not specify whether the unit is ambient, water bath, or steam-heated, nor does it provide dimensions, weight, utility connections, or heat input requirements. Request a dimensional drawing, utility specifications, and heat medium requirements from the seller.

What should I inspect on a used vaporizer before buying?

Verify the ASME U stamp data plate is intact and legible, check the shell and heads for corrosion or mechanical damage, and inspect all nozzles and flanges for distortion or cracking. Internal inspection should confirm the stainless lining condition if accessible, and you should request hydrostatic test records or plan for pressure testing to verify integrity at the 700 PSIG rating. Heat exchange surfaces (fins, coils, or tubes depending on design) should be examined for fouling, corrosion, or impact damage that would reduce capacity.
