Cryogenic tankers are specialized, highly insulated pressure vessels designed to transport and store liquefied gases (such as nitrogen, oxygen, argon, LNG, and hydrogen) at temperatures below -150C. Utilizing vacuum-insulation (inner and outer shells) to minimize heat transfer, they ensure the safety and stability of cryogenic liquids. These tanks are used in various industrial applications, including healthcare, aerospace, and energy.
Key Features and Design Components
- Insulation: Uses vacuum-insulation and often multiple layers of insulation material between an inner stainless steel/aluminum vessel and an outer shell.
- Capacity: Road tankers typically handle 4,500 to 5,550 gallons, though stationary storage can exceed 450,000 litres.
- Pressure Management: Equipped with pressure-relief valves to manage, or “breathe,” internal pressure changes.
- Operating Temperatures: Designed to handle temperatures ranging from -196C to +50C.
Types of Cryogenic Tankers
- Road Tankers: Specifically designed for transporting, for example, liquid oxygen or nitrogen.
- ISO Containers: Standardized 10 to 40-foot containers for intermodal transport.
