New in gas technology

Elliott Group offers a new cryogenic expander Elliott Group released an impulse-type, two-phase cryogenic expander that enables the expansion of liquefied gases into two-phase mixtures. Harnessing the energy of two-phase expansion increases the expander’s generator output, reduces boil-off losses and improves the overall liquefaction and cooling processes. Each expander is custom-designed and built for use in liquefied natural gas (LNG) liquefaction, refrigeration and separation processes. This technology optimizes staging to minimize axial load at the radial ball bearings. Due to its ability to tolerate a high content of vapor mass, it is offered for liquefaction and refrige
