Title: Method of producing rectified alcohol
Inventor: PERELYGIN VIKTOR MIKHAJLOVICH
IPC: B01D3/14
Filed: 1996-02-22
Granted: 1997-10-10
Abstract: FIELD: alcohol industry. SUBSTANCE: alcohol is digested from brew in brew-epuration column accompanied with transferring ethyl alcohol into brew distillate with vapor effluent from this column. Brew distillate is purified from head and intermediate impurities including fusel oil in epuration column involving hydroselection operation. Epurate is rectified in alcohol column to yield fusel oil fractions, fusel alcohol, and non- pasteurized ethyl alcohol fractions. Fusel oil and fusel alcohol fractions are rectified in fusel column, fusel oil being withdrawn from accumulator drum. Ethyl alcohol is additionally purified by way of removing fusel-ester-aldehyde-methanol fractions from carbon dioxide separator condenser, condenser, and alcohol trap of brew- epuration column, as well as methanol-ester-aldehyde fraction from condenser of methanol column which is fed with liquid from dephlegmator of brew-epuration column and heated by epurated water- alcohol vapor from this column. Epuration of brew distillate is carried out in epuration column with feeding hot water onto upper tray of the column and withdrawing brew-ester-aldehyde-methanol fraction from its condenser. This fraction along with fractions from carbon dioxide separator condenser, condenser, and alcohol trap of brew- epuration column is used as additional feed for brew column. From liquid phase taken from 28-36th trays of this column, propyl alcohols' fraction is isolated and methanol-ester-aldehyde fraction is withdrawn from its condenser. These fractions together with those from methanol and alcohol column condensers are used as feed for distillation column. Middle zone of digestion part of the latter receives hot water and head fraction concentrate is taken from this column's condenser. Concentrate of propyl alcohols is taken from liquid phase from the tray located over hot water introduction point, whereas water- alcohol liquid is withdrawn from the still and returned into brew. EFFECT: improved process flowsheet. 1 tbl, 1 dwg

Abstract: Изобретение относится к области газовой промышленности и может быть использовано при получении товарного сжиженного газа. Сущность изобретения заключается в абсорбции углеводородов С 3 -С 4  углеводородным поглотителем под давлением с последующей регенерацией насыщенного поглотителя путем ступенчатого фракционирования с возвратом его на стадию абсорбции. Причем абсорбцию осуществляют под давлением 53-56 атм и в качестве поглотителя используют углеводородную фракцию С 9 -С 11 , затем насыщенный поглотитель подвергают дросселированию до давления 30 атм и трехступенчатому фракционированию под давлением с отводом товарного сжиженного газа со второй ступени. При этом фракцию С 1 -С 2  со стадии дросселирования подают на стадию абсорбции. Также первую ступень фракционирования осуществляют под давлением 14 атм. Кроме того, углеводородную фракцию С 1 -С 2  с первой ступени фракционирования возвращают на стадию абсорбции. При этом вторую ступень фракционирования осуществляют под давлением 13 атм, а фракцию углеводородов С 3 -С 4  со второй ступени фракционирования после очистки ее от меркаптанов известным методом отводят потребителю. Третью ступень фракционирования осуществляют под давлением 1,8 атм, а фракцию углеводородов С 9 -С 11  с третьей ступени фракционирования делят на два потока в объемном соотношении 3:1, первый из которых подают на стадию абсорбции, а второй - на первую ступень фракционирования. 7 з. п. ф-лы, 1 ил.

Abstract: FIELD: radiation monitoring of environment including monitoring of activity of alpha radiating nuclides. SUBSTANCE: method involves taking samples and preparing them for measurement using liquid scintillation counter, measuring and recording sample spectrum and measurement parameters, convoluting hardware spectrum of sample into group, producing model spectrum of sample on the basis of library base spectrums, minimizing model spectrum deviation from sample spectrum, and determining content of radionuclides in sample. Alpha radiating nuclides are identified in samples when interference radionuclides are present in taken samples. To this end, in preparing solid sample, it is annealed before opening, then opened by means of concentrated nitrous acid and hydrogen peroxide, concentrated by evaporation to wet salt state, wet residue it transformed to hydrochloric acid solution and concentrated by evaporation. Concentrated orthophosphoric acid is added to solution obtained and concentrated by evaporation. Solution is cooled down and transferred to scintillation mixture. Sample is measured by means of liquid scintillation counter, specimen spectrum obtained is recorded and grouped. Deviation of model spectrum from sample one is minimized. Specimen obtained has adequate degree of quenching which makes it possible to discriminate and identify alpha active nuclides in the background of accompanying radionuclides with high degree of accuracy.
