Известен способ контрол  состава сырь  процесса ректификации по температуре сырь  и давлению в колонне. Недостатком известного способа  вл етс  его невысока  точность при колебани х доли отгона в сырье. С целью устранени  указанного недостатка автоматически стабилизируют перепад давлений на вертикальном участке сырьевого трубопровода воздействием на подачу теплоносител  в подогреватель.There is a method of controlling the composition of the raw material of the rectification process according to the temperature of the raw material and the pressure in the column. The disadvantage of this method is its low accuracy when the fraction of the distillate in the raw material fluctuates. In order to eliminate this drawback, the differential pressure in the vertical section of the raw pipeline is automatically stabilized by affecting the flow of coolant to the preheater.

Стабилизаци  доли отгона сырь  за счет стабилизации веса столба сырь  основана на том, что вес столба частично испаренного сырь  в жидкой фазе существенно зависит только от доли отгона. Поэтому стабилизаци  веса столба перепада давлений на вертикальном участке сырьевого трубопровода непосредственно перед местом ввода в колонну обеспечивает стабилизацию доли отгона .Stabilization of the share of distillation of raw materials due to the stabilization of the weight of the column of raw materials is based on the fact that the weight of the column of partially evaporated raw material in the liquid phase only depends on the fraction of the distillate. Therefore, the stabilization of the weight of the pressure drop column in the vertical section of the feedstock pipeline directly in front of the entry point into the column ensures the stabilization of the distillate fraction.

По температуре сырь  и давлению в колонне при известной доле отгона сырь  можио определить содержание в сырье дистилл тных компонентов.The content of distillate components in the feedstock can be determined by the temperature of the feedstock and the pressure in the column with a known proportion of the distillate feedstock.

Предлагаемый способ по сн етс  чертежом .The proposed method is illustrated in the drawing.

Сырье по трубопроводу / через подогреватель 2 поступает в колонну 3. Вес столба сырь  между кранами 4, измер емый дифманометром 5, стабилизируетс  с помощью 5 регул тора 6 и клапана 7 изменением подачи теплоносител  в подогреватель 2. Температура сырь  на входе в колонну измер етс  с помощью датчика 8 и прибора 9, давление в колонне - с помощью прибора 10. СигналыThe raw material through the pipeline / heater 2 enters column 3. The weight of the column of raw materials between taps 4, measured by the differential pressure meter 5, is stabilized by means of the 5th regulator 6 and valve 7 by changing the coolant supply to the heater 2. The raw material temperature at the column inlet is measured with using the sensor 8 and the device 9, the pressure in the column - using the device 10. Signals

Этот сигнал регистрируетс  с помощью прибора 12 и может быть использован0 from devices 9-10 is fed to calculator 11, where a signal is processed that is proportional to the content of distillate fractions in the feedstock. This signal is recorded with instrument 12 and can be used
