Abstract: A distillation method and apparatus especially adapted for the desalination of water, in which bodies of a vaporizable liquid such as water are maintained in contact with opposite sides, respectively, of a microporous membrane non-wettable by the liquid and having through pores for passing the vapor of the liquid, the vapor of the liquid is caused to pass through the membrane by heating one body of liquid while cooling the other and substantially all gas except the vapor of the liquid is removed from the pores of the membrane by degassing at least the heated liquid prior to introducing it into contact with the membrane.

Abstract: 1,096,678. Multiple effect distillation apparatus; desalination of water. PACTIDE CORPORATION. Nov. 18, 1966 [Nov. 26, 1965; May 26, 1966], No. 51715/66. Addition to 1,096,677. Heading B1B. A multiple effect distillation apparatus comprises porous membranes 10, which are permeable to the vapour of the liquid being distilled but impermeable to the liquid itself, arranged in alternate stacked relationship with corrugated heat-conductive barriers 12, which are impermeable to both liquid and vapour. The liquid to be distilled, e.g. salt water, flows through the channels formed by the underside of each porous member 10 and the upper surface of the adjacent corrugated barrier 12, the flow being in the direction of the corrugations. Distillate liquid, potable water, flows through the other channels. A gasket 26, in the form of a frame, is disposed between each porous member and the adjacent barrier; and the whole assembly is clamped between header plates. The lower header plate 16 is supplied with heat, e.g. by solar energy; and partial vaporization of the distilland in the lowermost channel takes place, the vapour diffusing through the porous membrane and condensing in the distillate liquid flowing through the channel above. The heat of condensation is given up through the heat-conductive barrier to the distilland in the third channel, this multiple-effect operation being repeated in the remaining channels. The upper header plate 14 is cooled, e.g. by feed liquid. The feed liquid is supplied to channel 46 in manifold 40, from which the feed flows through alternate channels of the still, the unevaporated liquid being collected in and discharged from manifold 42. The distillate liquid flows in the opposite direction through the other channels, and is withdrawn through channel 48 in manifold 40. The heat-conductive barriers 12 may be made of copper, aluminium, polyvinylidene fluoride, or a polycarbonate. The porous membranes 10 may be made of polyvinyl chloride, a cellulose derivative, nylon, or polytetrafluorethylene.
