Abstract: A condensing assembly for urging condensation of a vapour into a liquid has a vertically stacked modular array of horizontal condensation units exposed to a heat transfer medium. Each condensation unit has a cooling chamber, a plurality of hollow legs and necks accessing the cooling chamber to define a fluid passageway. An open or enclosed space between vertically opposed condensation units is created by coupling the necks and legs of opposed condensation units. Introduced vapour travels along the fluid passageways and through the cooling chambers for condensation into liquid, which then travels along the fluid passageways to a storage tank. A cooling loop in each cooling chamber increases condensation. Vapour funnels in the condensation units along the fluid passageway reduce vapour to liquid contact therealong. An inlet header provides additional cooling to the vapour prior to entering the condensation units.

Abstract: A containment assembly for storing a liquid substance above a ground support surface has an inner tank for receiving and storing the liquid and an outer tank surrounding the inner tank and forming a first air space therebetween for trapping any of the liquid which might escape said inner tank. A support beneath the outer tank provides a second air space between the outer tank and the ground support surface, and a thermal insulating layer substantially envelopes the inner tank, outer tank and support from the ambient. A vapour exhaust vent is provided atop the inner tank, which may include a liquid scrubber for recovering liquids from discharging gases and returning the liquids to the inner tank or elsewhere. Piping is provided for liquid communication between the inner tank and external liquid sources for filling and emptying the inner tank.
