Description

Предметом изобретени   вл етс  технологическа  схема дл  мощной воздухоразделительной установки, позвол юща  ироизвольно располагать колонны высокого и низкого /давлени . Описываема  установка обличаетс  от известных установок д,5ч получени  жидкого кислорода те, что, с целью произвольного относительного расположени  ректификационных колонн высокого и LiisKoro давлени , в ней применен турбодстандор дл  создани  холодопроизводительности в установке Зс: счет расщнрени  испаривщейс  кубовой жидкости от промежуточного давлени  до давлени  верхней колонны ((гизкого давлени ) и, кроме того, использовано образование  зотной флегмы дл  орошени  колонны высокого давлени  за счет исларенн  кубовой л идкости прн про.межуточном давлении.The subject of the invention is a technological scheme for a high-capacity air separation plant, allowing for high and low / high pressure columns to be positioned spontaneously. The described installation is exposed from known installations for generating liquid oxygen for 5 hours, such that, in order to arbitrarily locate high distillation columns and Liis Koro pressure, it uses a turbo-standard to create a cooling capacity in an installation Cc: the expansion of the evaporating bottom liquid from intermediate pressure to upper pressure the column ((low pressure) and, in addition, the formation of white phlegm was used to irrigate the high pressure column due to islamic cubic liquid about interstitial pressure.

На чертеже изображена принцип;-:альна  технологическа  схема, допускающа  произвольное относительное расположение колонн высокого и низкого давлений.The drawing shows the principle; -: The technological scheme allows arbitrary relative positioning of high and low pressure columns.

Воздух, сжатый в турбокомпрессо ,ре. / до 6 ата проходит через регенераторы 2 и 3, где охлаждаетс , очилдаетс  и поступает в колонну высокого давлени  4. Кислородна  жидкость из куба колонны высокого давлени  переохлаждаетс  в переохладителе 5 отход щим азотом и дросселируетс  до давленн  примерно 3,2 ата в конденсатор 6. Здесь эта жидкость испар етс  за счет тепла конденсации азота, последний ндет на орошение колонны высокого давлени  4. Испаривша с  кубова  жидкость подогреваетс  и расшир етс  в турбодетандоре 7 до давлени  верхней колонны, при этo производитс  холод. Расшир емый газ поступает в среднюю часть верхней колонны. Несконденсированна  в колонне высокого давлени  часть газообразного азота после некоторого подогрева дл  улучшени  ректификации поступает в конденсатор 8 колонны низкого давлени , где сжи/каетс  и после переохлаждени  в переохладителе 5 дросселируетс , на верхнюю тарелку колонны 9. Продукт отводитс  из нижней части колонны низкого давлени  9.Air compressed in a turbo compressor, re. (up to 6 at.) passes through regenerators 2 and 3, where it cools, precipitates and enters the high pressure column 4. The oxygenous liquid from the bottom of the high pressure column is supercooled in subcooler 5 with waste nitrogen and throttled to about 3.2 bar pressure to condenser 6. Here, this liquid evaporates due to the heat of condensation of nitrogen, the latter is used to irrigate the high-pressure column 4. The evaporated from the bottom of the liquid is heated and expanded in the turbo-expander 7 to the pressure of the upper column, when this is cold. The expandable gas enters the middle part of the upper column. The non-condensed part of the gaseous nitrogen in the high pressure column after some heating to improve the rectification enters the low pressure column condenser 8, where it is compressed and condensed in subcooler 5 to the upper plate of the column 9. The product is withdrawn from the bottom of the low pressure column 9.
