(54) СПОСОБ РЕГУЛИРОВАНИЯ ПРОЦЕССА ОЧИСТКИ РАСТВОРИТЕЛЯ ОТ ПРИМЕСЕЙ(54) METHOD OF REGULATING THE PROCESS OF CLEANING SOLVENT FROM IMPURITIES
1one
Изобретение относитс к автоматизации производственных процессов и может быть использовано в производстве синтетического каучука.This invention relates to the automation of industrial processes and can be used in the production of synthetic rubber.
Известен способ регулировани процесса очистки растворител от примесей путем азеотропной осушки в колонне , заключающийс в стабилизации величины соотношени компонентов катализатора при смешении растворител и компонентов катализатора изменением расхода растворител или алюминиевого компонента катализатора 1.There is a method of controlling the solvent purification process from impurities by azeotropic drying in the column, which consists in stabilizing the ratio of the catalyst components by mixing the solvent and the catalyst components by varying the flow rate of the solvent or the aluminum component of the catalyst 1.
Известный способ обладает ограниченным возможност ми в отношении снижени концентрации примесей в растворителе из-за наличи возмущений по составу примесей.The known method has limited possibilities in terms of decreasing the concentration of impurities in the solvent due to the presence of disturbances in the composition of the impurities.
Цель изобретени - снижение концентрации примесей в растворителе.The purpose of the invention is to reduce the concentration of impurities in the solvent.
Указанна цель достигаетс тем, что по известному способу регулировани процесса очистки растворител от примесей путем азеотропной осушки в колонне, заключающемус в стабилизации величины соотношени компонентов катализатора при смешении растворител и компонентов катализатора изменением расхода растворител или алюминиевого компонента катализатора,This goal is achieved by the fact that according to a known method of controlling the solvent purification process from impurities by azeotropic drying in a column, which consists in stabilizing the ratio of the catalyst components when the solvent and catalyst components are mixed by changing the solvent or aluminum catalyst component,
дополнительно измен ют величину отгона паровой фазы из колонны в зависимости от указанного расхода растворител или алюминиевого компонента катализатора. При этом величину отгона паровой Лазы из колонны можно стабилизировать изменением расхода пара в кип тильник колонны.The value of the stripping of the vapor phase from the column is additionally changed depending on the indicated consumption of the solvent or the aluminum component of the catalyst. In this case, the amount of distillation of the steam Laz from the column can be stabilized by changing the steam flow rate in the column boiler.
Ил.гаострацией описываемого способа Illustrated by the described method
0 регулировани процесса очистки растворител от примесей вл етс система регулировани , блок-схема которой приведена на чертеже.0 regulating the process of purifying a solvent from impurities is a regulating system, a block diagram of which is shown in the drawing.
Возвратный растворитель подаетс Return solvent is supplied
5 на колонну 1 азеотропной осушки. Расход пара в кип тильник 2 колонны 1 стабилизируетс регул тором 3, получающим информацию от датчика 4 расхода и воздействуюгчим на клапан 5. Рас0 ход (отгон) па ровой Лазы из колонны 1 регулируетс регул тором 6, получающим информацию от датчика 7 расхода и воздействующим на задание регул тору 3 расхода пара. Небольша часть 5 to column 1 azeotropic drying. The steam flow rate into the boiler 2 of column 1 is stabilized by the controller 3, which receives information from the sensor 4 of the flow and acts on the valve 5. The flow (distillation) of the vapor port from column 1 is regulated by the controller 6, which receives information from the sensor 7 and acts on setting the steam flow controller 3. Small portion
5 осушенного растворител , поступаю- щего из куба колонны 1 азеотропной осушки, байпасируетс по трубопроводу 8 и расход его регулируетс регул тором 9, получающим информацию 0 от датчика 10 расхода и воздействую5 of the dried solvent coming from the bottom of the column 1 of azeotropic drying is bypassed through conduit 8 and its flow is controlled by regulator 9, which receives information 0 from flow sensor 10 and acts
