Abstract
Abstract 829,915. Storing liquefied gases. ESSO RESEARCH & ENGINEERING CO. Nov. 21, 1956 [Dec. 12, 1955], No. 35599/56. Class 8(2) [Also in Group XXXIII] A transportable vessel for storing liquefied hydrocarbons of low boiling point e.g. methane at substantially atmospheric pressure comprises an inner container 23 lined with heat insulating material 25 e.g. balsa wood having a liquid-proof lining 29 and submerged in a tank 8 of hydrocarbon liquid of much higher boiling point e.g. petroleum capable of absorbing gas in either the liquid or gaseous phase leaking from the inner container 23. The container 23 which has a vent 33 and a liquid inlet and discharge duct 31 is held by saddles 17, 19, 21 within the tank 8 which also has a vent 39 and a supply and discharge line 37. A plurality of such vessels may be located in the hold of a ship (see Group XXXIII) the engines of which may be fuelled by vented gas. Reference has been directed by the Comptroller to Specification 766,128.
