CRYOGENIC PLANT Russian patent published in 2004 - IPC

FIELD: vessels for containing of liquefied and solidified gases. SUBSTANCE: cryogenic plant has two-walled vessel for cryogenic product storing. Vessel comprises screen-and-vacuum insulation arranged in gap between vessel walls and cooled screen. Adsorbent is applied to vessel inner wall. Plant has cryogenic product circulation loop which includes vessel inner enclosure, cooled screen channels, combined end part, cooled screen outlet device, check valve, liquefier and circulating means. All loop components are sequentially connected by pipeline. Circulating means communicates with vessel inner enclosure. Combined end part is located in gap between screen-and-vacuum insulation layers. EFFECT: increased cryogenic product storage time due to enhanced absorbing performance of absorbent and decreased heat penetration due to maintaining of cryogenic product constant level into vessel. 1 dwg
