RESERVOIR FOR CRYOGENIC LIQUID Russian patent published in 2008 - IPC F17C3/08 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to reservoir for cryogenic liquid and can be used as filling facility of off-site objects. The reservoir contains a shell and a vessel therein; the said vessel is mounted on low heat conducting supports, resting on a screen, which envelops the vessel; the screen is placed in vacuum insulating space of the vessel in the shell; the shell with the low heat conducting supports prevents the vessel's movements; at that part of the screen is assigned for cooling agent. The vessel and the screen are secured with lengthwise chains on end ribs of a cylinder portion of the shell thus providing temperature shrinkage of the vessel and the screen in opposite directions on the supports. Each support is divided in two parts with the screen. The upper portion of the support is assembled with radial axis set-off against the radial axis of the lower portion of the support at a value of screen shrinkage at the point of support installation and in the direction opposite to shrinkage. The upper portion of the support is mounted on the screen freely contacting with the surface of the vessel, while the lower portion of the support is installed on the shell freely contacting with the surface of the screen. Bases of portions of the support on the screen and on the shell are made with ring rests maintaining portions of the support from set-off at shrinkage of the vessel and screen.

EFFECT: facilitating minimal gaps between a shell and screen and maximum net volume of a vessel in a reservoir.
