Abstract: FIELD: alcohol production. SUBSTANCE: alcohol is digested from brew in brew column to transfer ethyl alcohol and accompanied admixtures into brew distillate with column vapors. Brew distillate is freed from head and intermediate impurities including fusel oil components in epuration column using hydroselection. Epurate is subjected to rectification in alcohol column to run off fusel oil, fusel alcohol, and non-pasteurized alcohol fractions. Head fractions of ethyl alcohol are distilled in distillation column receiving hot water into middle part of its digestion zone. Head fraction concentrate is withdrawn from condenser, whereas concentrate of propyl alcohols, taken off from liquid phase of the plate disposed over inlets for hot water and water-alcohol liquid from still, is returned into brew. Ethyl alcohol is purified in additional rectification column fed with vapor and its condensate from brew preheater and liquid fractions from condenser of carbon dioxide separator and alcohol collector. From condenser of this column, head fraction is withdrawn and fed onto feeding tray of distillation column. Fusel oil fraction is isolated from vapor phase of 5-11 trays of digestion zone of additional column, whereas brew distillate is run off from the top part of this column and used to feed epuration column.

Granted: 2000-04-27
Abstract: FIELD: ferrous metallurgy. SUBSTANCE: invention relates to electrometallurgy and, more specifically, to electroslag refining of metals that can be used for working tool steel. Proposed flux contains part of components, in particular, calcium, aluminum, and silicon oxides, and to some extent magnesium oxide incorporated therein in the form of regenerated blast furnace slag formed by desulfurization of blast furnace slag in emulsion- and flow-drop-mode processes. Components are used in the following proportions, wt.%: regenerated blast furnace slag, 75-80; magnesium oxide, 15-20; and calcium fluoride, 4-5; slag is composed, wt.%: silicon oxide, 40-45; calcium oxide, 40-42; aluminum oxide, 10-12; magnesium oxide, 8-9; and sulfur, <0.2. Introduction of regenerated blast furnace slag makes it possible to abolish high-priced technologies for separately preparing each slag component involved. In addition, necessity of expenses on ensuring transportation and storage conditions for separately prepared flux components is avoided. Reduced level of calcium fluoride to its limits ensuring normal proceeding of electroslag refining process, in particular, ensuring required fluidity of slag and conductance of fusion, also contributes to reduced cost price of flux and, additionally, leads to reduced emission of fluoric compounds into atmosphere. EFFECT: enhanced process efficiency. 1 tbl

Цилиндрическая стенка камеры выполнена из прозрачного материала, например стекла, и внутри камера заполнена инертным газом. Трубка выполнена из тугоплавкого металла с поверхностью, обладающей свойством минимального отражения солнечных лучей, причем для увеличения поверхности съема тепла рабочей средой внутри трубки с контактированием с ее внутренней поверхностью установлен стержень из тугоплавкого металла с винтовой нарезкой. Торцевые крышки и патрубки выполнены из теплоизоляционного материала, выдерживающего температуру до 2000 o С. Величина температуры нагрева рабочей среды зависит от скорости прохождения ее через трубку, длины трубки и температуры нагрева трубки, которая в свою очередь зависит от количества цилиндрических собирающих линз и их площади, перпендикулярной к падающим солнечным лучам. Изобретение позволяет повысить величину общей результирующей температуры нагрева металлической трубки и производительности теплообменника. 4 ил.
