Abstract: In the processing of a corrosive liquid mixture, such as 50 to 80% aqueous sulfuric acid, by its passage over one surface of a wall of inert heat resistant material, and heating the other surface of said wall, thereby to evaporate from said corrosive liquid mixture the more volatile component thereof, the improvement which comprises heating said wall by contact with an inert liquid material, and heating said inert liquid material indirectly through heat exchange with a normally solid molten material. Desirably the wall of inert material is a pipe surrounded by a molten metal in a first annular jacket and a molten salt in a second annular jacket.

Abstract: In the removal of water from a gas by contact with sulfuric acid, the improvement which comprises supplying the sulfuric acid in finely divided form having a surface of about 10.sup.4 to 10.sup.7 m.sup.2 /h at a concentration of about 95 to 99% and a temperature of about 35.degree. to 80.degree. C and with a contact time of about 0.2 to 2 seconds, whereby the residual moisture content of the gas is reduced to about 30 to 250 mg of H.sub.2 O/Nm.sup.3. Preferably the sulfuric acid is sprayed through a constriction into a vessel through which the gas is passed. The large sulfuric acid surface area permits high levels of dehydration to be achieved with far less sulfuric acid than heretofore believed possible and with small vessels and minimal contact times. Contact may be effected serially in several stages with the spent acids combined, brought up to initial concentration and recirculated.
Abstract translation: 在通过与硫酸接触从气体除去水时，其改进包括以约95至99％的浓度提供具有约104至107m 2 / h表面的细碎形式的硫酸和温度 约35℃至80℃，接触时间约0.2至2秒，从而将气体的残留水分降低至约30至250mg的H 2 O / Nm 3。 优选地，硫酸通过收缩部喷射到气体通过的容器中。 大的硫酸表面积允许以比迄今所认为可能的少得多的硫酸和小容器和最小的接触时间来实现高水平的脱水。 接触可以在几个阶段中连续进行，废酸组合，达到初始浓度并再循环。
