Title: Combined pervaporation-vapour permeation process
Inventor: BRUESCHKE HARTMUT E A
IPC: B01D61/36
Filed: 1994-03-24
Granted: 1995-06-29
Abstract: In a process to separate liquid mixtures by combined pervaporation and vapour permeation, a vapour-liquid mixture is brought into contact with a non-porous membrane. The novelty is that the incoming vapour-liquid mixture is presented to the vertically-arranged membrane from below and passes upwards over the membrane surface, so that there is a continual mixing of vapour and liquid, and that no stationary liquid film can form upon the membrane surface. The vapour-liquid inflow has a molar vapour proportion of 90 per cent to 150 per cent of the molar permeate flow. The inflowing vapour and liquid are delivered by separate pipes at a temperature above the atmospheric boiling point.

Abstract: FIELD: exhaust systems of internal combustion engines. SUBSTANCE: during operation of internal combustion engine, exhaust gases enter exhaust pipe line. This flow partially forces, through branch pipe, aqueous solution containing lime water and nonionic surface-active substance out of reservoir to high-temperature gas flow through sprayer. Simultaneously, aqueous solution of carbamide is forced out of reservoir through supply pipe and sprayer. Carbon monoxide, sulfur oxide and sodium oxide are chemically neutralized in exhaust pipe line. Then, moving flow enters silencer. In mixing chamber filled with granules of expanded clay aggregate, flow is intensively swirled and its noise is absorbed. Besides that, expanded clay aggregate is used as solid porous carrier on which unreacted carbide falls out and crystallizes; it is also used for further neutralization of nitrous gases and nitric and nitrous acids.
