Изобретение относитс к способу управлени процессом ректификации и может примен тьс в нефтехимической и химической промышленности.The invention relates to a method for controlling a rectification process and can be used in the petrochemical and chemical industries.
Известен способ автоматического управлени процессом разделени смеси путем регулировани расхода дистилл та в зависимости от расходов исходных компонентов с учетом концентрации одного из потоков 1.A known method of automatically controlling the process of separation of the mixture by adjusting the distillate consumption, depending on the costs of the initial components, taking into account the concentration of one of the streams 1.
Известен способ автоматического управлени процессом разделени смесей в последовательно соединенных массообменном аппарате и ректификационной колонне путем поддержани заданного соотношени расходов исходных компонентов 2. Но он не обеспечивает высокого качества раздел емых продуктов .A known method of automatically controlling the process of separation of mixtures in series-connected mass transfer apparatus and distillation column by maintaining a given cost ratio of the initial components 2. But it does not provide high quality products to be separated.
С целью повышени качества раздел емых продуктов предлагают способ, в котором соотношение расходов исходных компонентов корректируют в зависимости от разности концентраций потоков на выходе из массообменного аппарата и в питательной части ректификационной колонны.In order to improve the quality of the products to be separated, a method is proposed in which the cost ratio of the initial components is adjusted depending on the difference in the concentration of flows at the outlet of the mass transfer apparatus and in the nutrient part of the distillation column.
На чертеже представлена схема реализации способа автоматического управлени процессом .разделени смесей.The drawing shows the scheme of implementation of the method of automatic control of the process of separation of mixtures.
Способ осушествл етс следующим образом .The method is as follows.
В массообменный аппарат 1, например экстрактор, поступают исходна смесь и растворитель . Из экстрактора смесь целевого продукта вместе с растворителем направл ют в ректификационную колонну 2 на разделение . Регулирование подачи растворител производитс регул тором 3 соотношени , получающим сигналы от датчиков 4, 5 расходов растворител и раздел емой смеси.In the mass transfer apparatus 1, for example an extractor, the initial mixture and solvent are fed. From the extractor, the mixture of the desired product, together with the solvent, is sent to distillation column 2 for separation. The regulation of the solvent supply is made by the 3 ratio controller, which receives signals from the sensors 4, 5 of the solvent flow rate and the mixture to be separated.
Корректирующий сигнал в регул тор 3 соотношени подают от преобразовател 6 разности концентраций, св занного с датчикомThe correction signal to the controller 3 ratios is supplied from the converter 6 of the concentration difference associated with the sensor
