Изобретение относитс к способам регулировани работы реакторов и может примен тьс в процессах нефтеперерабатывающей, нефтехимической и Х имической промышленности .The invention relates to methods for regulating the operation of reactors and can be used in the processes of the petroleum refining, petrochemical and chemical industries.
Известен способ автоматического управлени работой реакторов путем изменени расхода одного из компонентов в зависимости от температуры смеси и стабилизации расхода хладагента. Однако указанный способ не обеспечивает требуемого выхода целевого продукта .There is a known method of automatically controlling the operation of reactors by changing the flow rate of one of the components depending on the temperature of the mixture and stabilizing the flow rate of the refrigerant. However, this method does not provide the desired yield of the target product.
Дл увеличени выхода целевого продукта предлагаетс регулировать соотношение расходов компонентов с коррекцией по температуре смеси на выходе из реакторов и расход хладагента в зависимости от разности температур смеси на выходе из реакторов и хладагента на входе реакторов.In order to increase the yield of the target product, it is proposed to adjust the ratio of the flow rates of the components with correction for the mixture temperature at the reactor outlet and the coolant flow rate depending on the temperature difference of the mixture at the reactor outlet and the refrigerant at the reactor inlet.
На чертеже показана схема реализации описываемого способа.The drawing shows the implementation of the described method.
Способ осуществл ют следующим образом.The method is carried out as follows.
Сигналы с датчиков расхода 1 и 2, установленных на лини х подачи сырь и раствора карбамида в реакторы, поступают в регул тор соотношени 3, выход которого св зан с клапаном 4, расположенным на линии подачиThe signals from flow sensors 1 and 2, installed on the lines of supply of raw materials and urea solution to the reactors, enter the ratio controller 3, the output of which is connected to valve 4 located on the supply line
раствора карбамида. На регул тор соотношени подают корректирующий сигнал от датчика температуры 5 реакционной смеси на выходе из последнего реактора через программное устройство 6. Регул тор 7 разности температур , на который поступает переменна с суммирующего блока 8, получаема в результате вычитани сигналов с датчиков температур 5 и 5 реакционной смеси и хладагента, управл ет регулирующим клапаном 10, установленным на линии подачи охлаждающей воды.urea solution. The ratio controller is supplied with a correction signal from the temperature sensor 5 of the reaction mixture at the outlet of the last reactor through the software device 6. The temperature difference controller 7, which is variable from the summing unit 8, is obtained by subtracting the signals from the temperature sensors 5 and 5 of the reaction mixture mixture and refrigerant, controls the control valve 10 installed in the cooling water supply line.
Предмет изобретени Subject invention
Способ автоматического управлени работой реакторов путем 1изменени расходов компонентов и хладагента, отличающийс тем, что, с целью увеличени выхода целевого продукта , регулируют соотношение расходов компонентов с коррекцией но температуре смесн на выходе из реакторов и расход хладагента в зависимости от разности температур смеси на выходе из реакторов и .хладагента на входе реакторов.A method of automatically controlling the operation of reactors by changing the flow rates of components and refrigerant, characterized in that, in order to increase the yield of the target product, the ratio of the flow rates of components with correction at the reactor outlet temperature and refrigerant flow is controlled depending on the temperature difference of the mixture at the reactor outlet and coolant at the reactor inlet.
