HEAT- AND MASS-TRANSFER APPARATUS Russian patent published in 1997 - IPC

FIELD: mechanical engineering, particular, apparatuses for thermal separation of mixtures; applicable in distillation processes, mainly, in rectification of methanol from water-methanol mixtures usable in oil producing industry for decreasing of viscosity of oil raw material, or for simple flash distillation. SUBSTANCE: the offered apparatus has body accommodating still provided with means for heating and multistage condenser, which presents a set of trays with desired product outlet and cooling coils. The apparatus is distinguished by the fact that means of heating is made in form of remote heat exchanger with burner of immersion combustion, whose upper and lower parts are interconnected by circulating pipelines with respective zones of still. EFFECT: higher efficiency. 1 dwg
