Предлагаемь1й способ относитс к методам автоматического регулировани непрерывных химических процессов по технологическим параметрам , в частности, к методам автоматического регулировани процесса полимеризации по в зкости, и может использоватьс в производстве синтетического каучука.The proposed method relates to methods of automatic control of continuous chemical processes according to technological parameters, in particular, methods of automatic control of the polymerization process of viscosity, and can be used in the manufacture of synthetic rubber.
Известен способ регулировани процесса полимеризации путем воздействи на расход компонентов каталитического комплекса в зависимости от параметров процесса и качественных показателей продукта.There is a method of controlling the polymerization process by affecting the consumption of the components of the catalytic complex depending on the process parameters and the quality indicators of the product.
С целью обеспечени устойчивости процесса подачу компонента или компонентов катализаторного комплекса осуществл ют в зависимости от промежуточного параметра, например от температуры в зоне реакции, конверсии мономера, в зкости полимеризата, перепада давлени полимеризата на участке полимеризационной батареи или мощности, потребл емой мешалкой реактора, а задание на этот параметр корректируетс в зависимости от отклонени в зкости полимера от заданного значени .In order to ensure the sustainability of the process, the component or components of the catalyst complex are supplied depending on the intermediate parameter, for example, the temperature in the reaction zone, the monomer conversion, the viscosity of the polymer, the pressure differential of the polymer on the polymerization battery or the power consumed by the reactor mixer, and the task this parameter is corrected depending on the deviation of the viscosity of the polymer from the specified value.
Предлагаемый способ по сн етс схемой регулировани молекул рного веса полимера в процессе полимеризации бутадиена в батарее, состо щей из реакторов.The proposed method is explained by a scheme for adjusting the molecular weight of the polymer during the polymerization of butadiene in a battery consisting of reactors.
Реакционна жидкость (раствор мономера в инертном растворителе) подаетс в реакторThe reaction liquid (monomer solution in an inert solvent) is fed to the reactor.

В реакторы 1 и 2 подаетс каталитический комплекс, причем его расход регулируют с помощью регул торов PKi и РКз концентрации полимера в реакционной массе, сигнал на которые поступает от датчиков ДК: и ДКз концентрации полимера. На последних реакторах п-I к п батареи измер етс качественный параметр1, from where the polymerizate enters the reactor 2 and further to the n-1 and n reactors. The catalytic complex is fed to the reactors 1 and 2, and its flow is regulated using the PKi and RKZ controls of the polymer concentration in the reaction mass, the signal to which comes from the sensors DK: and DKZ polymer concentration. In the last reactors p-i to p of the battery, the quality parameter is measured.
полимера, в данном случае молекул рный вес. Сигналы от датчиков ДМ1 и ДМ2 молекул рного веса через регул торы PMi и РМ.2 молекул рного веса поступают на логическое устройство ЛУ, позвол ющее учитывать одновременно изменение среднего молекул рного веса в обоих реакторах п- I и п.polymer, in this case molecular weight. The signals from the DM1 and DM2 molecular weight sensors through the PMi and PM.2 molecular weight regulators are fed to the LU logic device, which allows simultaneously taking into account the change in the average molecular weight in both n and I reactors.
