Abstract: FIELD: distillation processes and equipment. SUBSTANCE: invention concerns distillation processes involving petroleum raw material as well as materials treatable in chemical, food, pharmaceutical, and other industries. Essence of invention resides in that pumping off vapor-gas mixture from rectification column is performed with vacuum-generating arrangement, in particular, liquid-gas-jet apparatus connected with a closed container made in the form of phase separator and a pump forming in common circulating system; condensation of mixture occurs in phase separator in which vapor-gas-liquid mixture is separated into at least three phases, one of them in the form of non-condensed vapors and gases being withdrawn for utilization and liquid fractions after stratification into continuous phase layers being withdrawn from the phase separator as individual streams of objective fractions. As circulating agent for vacuum-generating arrangement either a part of one of fractions withdrawn of phase separator or water is utilized, while vapor of the latter may be introduced together with raw material or be fed into one of the sections of rectification column. A part of one of side distillates may also be utilized as circulating agent. Additionally jet apparatus is used as mixer to prepare high-disperse emulsion of circulating agent with one of the side distillates. Peculiar feature of installation consists in that circulation system is composed of hydraulically interconnected liquid-gas-jet apparatus, phase separator, and pump, phase separator being made as a closed vessel with (i) inlet zone for vapor-gas- liquid jet from delivery line of jet apparatus and (ii) condensate settling zone. Jet inlet zone is separated from settling zone by hydraulic gate in the form of suppresser-reflector of kinetic energy of jet, and settling zone is provided with connection pipes for separately withdrawing non-condensed vapors and gases and at least two liquid phases formed in settling zone after condensate is stratified into continuous layers. EFFECT: improved process flowsheet. 1 dwg

Abstract: FIELD: alcohol industry. SUBSTANCE: alcohol is extracted from mash in mash-epuration column while simultaneously removing associated impurities from mash distillate by means of tapping methanol-ester-aldehyde fraction from condenser of closed column supplied and heated by vapor from upper tray and fusel- ester-aldehyde-methanol fractions from condenser of carbon dioxide separator and alcohol trap, and epurating mash distillate in epuration column involving hydroselection operation. Epurate is rectified in alcohol column while withdrawing fusel oil, fusel alcohol, and non- pasteurized alcohol fractions. Fusel oil-containing vapor from feed tray is liberated from ethyl alcohol by washing with hot water which is fed into accumulation sheet-steel cylinder disposed in middle zone of concentration part of alcohol column from which fusel oil is tapped. Liquid from tray located over accumulation sheet-steel cylinder is directed onto feed tray to isolate fraction of propyl alcohols. Final purification of rectified alcohol from methanol, esters, aldehydes, and other head impurities is performed in methanol column which is heated through external boiler by water-alcohol vapor from mash-epuration column, its condensate being fed into middle zone of digestion part of epuration column. From condensate, liquid fraction is isolated which, together with fractions from condensers of epuration and alcohol columns is directed onto upper tray of closed column, into middle zone of which, fractions from condensers of carbon dioxide separator, alcohol trap, and mash preheater are fed, whereas, from condenser of closed column, head fraction of ethyl alcohol is drawn off.
