Insulated Pressure Vessels for LNG Industry
Roben, Mfg, Inc. specializes in insulated pressure vessels for LNG applications, providing vacuum-insulated and super-insulated vessels for liquefied natural gas storage, processing, and distribution. Our LNG insulated vessels feature advanced cryogenic insulation achieving minimal boil-off rates for efficient LNG handling throughout the supply chain from liquefaction to end-use.
What Are Insulated Pressure Vessels for LNG Industry?
Insulated pressure vessels for LNG are cryogenic containers designed for liquefied natural gas at approximately -260°F (-162°C), incorporating vacuum insulation or high-performance insulation systems that minimize heat leak and boil-off gas generation. These vessels serve LNG production facilities, distribution terminals, vehicle fueling, and industrial gas supply applications.

Frequently Asked Questions
What boil-off rates are achievable for insulated LNG vessels?
Well-designed vacuum-insulated LNG vessels achieve boil-off rates of 0.1-0.3% per day for large storage vessels and 0.3-0.8% per day for smaller distribution vessels. Boil-off rate depends on vessel size, insulation type, and ambient conditions.
What codes govern LNG pressure vessel design and construction?
LNG vessels must meet ASME Section VIII for pressure containment, NFPA 59A for LNG facilities, DOT regulations for transport, and 49 CFR 193 for LNG facilities. We design to applicable codes and coordinate with authorities having jurisdiction for specific installations.
How is boil-off gas managed in insulated LNG vessels?
Our LNG vessels include provisions for boil-off gas management including reliquefaction system connections, vapor return lines, pressure buildup coils for pressure maintenance, and relief systems. Boil-off can be recovered for fuel use or reliquefied depending on facility configuration.
