Изобретение относитс к способам управлени простой ректификационной колонной.This invention relates to control methods for a simple distillation column.
Оно предназначено дл максимизации разделительной способности процесса реактификации и может быть использовано в нефтеперерабатьгааю шей, нефтехимической, пищевой и других отрасл х промышленности, где имеет место разделение ректификацией.It is intended to maximize the separation capacity of the process of reactivation and can be used in petroleum refining, petrochemical, food and other sectors of the industry where there is separation by distillation.
Известен способ автоматического управпени процессом ректификации путем вычислени соотношени расходов флегмы и сырь с учетом состава сырь ij.There is a known method of automatic control of the rectification process by calculating the ratio of reflux to raw materials, taking into account the composition of the raw material ij.
Известен способ автоматического управлени процессом ректификации путем изменени расхода дистилл та в зависимости от соотношени между отбором дистилл та и расходом сырь , поступающего в ректификационную колонну и путем изменени подачи теплоносител в зависимости от расхода кубового остатка f2j.There is a known method for automatically controlling the distillation process by changing the distillate consumption depending on the ratio between the distillate selection and the consumption of raw materials entering the distillation column and by changing the coolant supply depending on the bottom residue consumption f2j.
Известный способ позвол ет стабилизировать составы дистилл та и кубового остатка .The known method makes it possible to stabilize the compositions of the distillate and the bottom residue.
Однако он не обеспечивает максималь ную разделительную способность ректификационной колонны.However, it does not provide the maximum separation capacity of the rectification column.
Целью изобретени вл етс обеспечеЕше максимальной разделительной способности ректификационной колонны. Это достигаетс тем, что расход дистилл та дополнительно измен ют в зависимости от состава сырь при одновременном поддержании расхода пара на оптимальном значении в зависимости от расхода и состава сырь .The aim of the invention is to provide the maximum separation capacity of the distillation column. This is achieved by the fact that the distillate consumption is additionally changed depending on the composition of the raw material while simultaneously maintaining the steam consumption at an optimum value depending on the consumption and the composition of the raw material.
На чертеже представлена схема реализа- зации способа автоматического управлени процессом ректификации. Способ осущабтвл етс следующим образом.The drawing shows a scheme for implementing a method for automatically controlling the rectification process. The method is carried out as follows.
Сигнал о расходе сырь , измеренный диафрагмой 1 с датчиком 2, поступает через компенсатор 3 на регул тор соотношени расходов 4. На него поступает также сигнал о расходе дистилл та, измеренный диафрагмой 5 с датчиком 6, и сигнал о доле легколетучих компонентов в сырье, измеренный датчиком состава 7 с преобразоваThe raw material consumption signal, measured by diaphragm 1 with sensor 2, is fed through compensator 3 to flow ratio controller 4. It also receives a signal for distillate consumption, measured by diaphragm 5 with sensor 6, and a signal for the proportion of volatile components in the raw material sensor composition 7 with transform
