Abstract

531,359. Evaporating liquids which foam; spray evaporators. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. July 19, 1939, No. 21011. Convention date, Aug. 9, 1938. [Class 32] Liquids which foam on heating, e.g. solutions of capillary active substances, particularly aqueous soap solutions, e.g. aqueous solutions of alkali or alkaline earth salts of sulphuric acid esters derived from olefines or alcohols, are concentrated by converting the solution into a liquid vapour mixture by heating it in a tube or the like and injecting the mixture at high velocity in the form of fine jets or films into a free space so dimensioned that the injected mixture gives off substantially the whole of its vapour before it reaches the wall of the space, separate discharge lines for the vapour and the concentrated solution being provided. The liquid is injected at a velocity of at least 100 metres per sec., and in the case of soap solutions is heated to 90-110‹ C. The solution may be injected through a hollow vertical tube closed at the bottom and provided with helically arranged holes forming spray outlets for the liquid. Alternatively the liquid may be sprayed through a tube on to a horizontal disc.
