Cryo Technologies’ vacuum cold box engineering, design and fabrication expertise affords us the ability to offer our customers helium liquefiers of unparalleled performance and quality. Our full range of engineering and design competencies include process, mechanical, instrumentation, controls, safety, procurement, quality assurance, project management and 3D modeling.
A warm, pure helium feed stream is compressed (if required) to achieve the liquefier high pressure stream design pressure. The pure, high pressure helium feed stream enters a vacuum cold box where it is cooled by liquid nitrogen and recycle refrigeration. Recycle refrigeration is provided by compressing a separate helium recycle stream and expanding it in one or more turboexpanders. The refrigerated helium feed stream is then expanded in a reciprocating expansion engine to produce a two-phase helium stream. The two-phase stream flows into a storage tank where the liquid and vapor are separated. The liquid helium remains in the storage tank and the cold helium vapor is returned to the cold box where it is used to cool the helium feed stream. A complete liquefaction system typically includes recycle and feed (where applicable) compressors, oil removal systems, a vacuum cold box containing heat exchangers, 80K & 20K adsorbers, turboexpanders and reciprocating expander(s), valves & instruments, product storage, distribution & trailer loading systems and control & analytical systems.
