Description

Известен способ регулировани  процесса полимеризации, проводимого в полимеризационной батарее при стабилизации конверсии мономера путем изменени  расхода катализатора .There is a method of controlling the polymerization process carried out in a polymerization battery while stabilizing the monomer conversion by changing the catalyst consumption.

В известном способе изменение реакционного объема реакторов головной части батареи, которое возникает из-за налипани  на поверхности мешалок полимера, может привести к перерасходу катализатора, и, как следствие, к увеличению себестоимости полимера.In the known method, the change in the reaction volume of the reactor head of the battery, which occurs due to sticking on the surface of the polymer mixers, can lead to catalyst overruns, and, consequently, to an increase in the cost of the polymer.

Дл  оптимизации процесса полимеризации по предлагаемому способу измер ют перепад давлени  на реакторах головной части батареи, при отклонении измеренных величин номинала в сторону увеличени  уменьшают величину заданного значени  конверсии в головной части батареи.In order to optimize the polymerization process according to the proposed method, the pressure drop across the reactors of the battery head is measured, and if the measured values deviate upwards, the value of the set conversion value at the battery head decreases.

На чертеже дана схема автоматического регулировани  процесса полимеризации в производстве изопренового каучука.The drawing is a diagram of the automatic regulation of the polymerization process in the production of isoprene rubber.

Предлагаемый способ состоит в Измерении перепада давлени  датчиком 1 давле ,ни . При увеличении этого перепада давленн  против номинала на головных реакторах батареи сигнал от датчиков 1 поступает в вычислительно-логический блок 2, который в соответствии с величиной полученных сигналов уменьшает задание регул тору 3 конверсии.The proposed method consists in measuring the pressure drop of the pressure sensor 1, nor. With an increase in pressure drop vs. nominal on the head reactors of the battery, the signal from sensors 1 enters the computational-logic unit 2, which, in accordance with the magnitude of the received signals, reduces the task to controller 3 conversions.

Регул тор 3 конверсии дл  поддержани  нового заданного значени  конверсии уменьшает задание регул тору 4 расхода катализатора.The conversion controller 3 to maintain the new conversion setpoint reduces the setting of catalyst consumption controller 4.

Таким образом, за счет снижени  расхода катализатора при заданной производительности полимеризационной батареи достигаетс  снижение себестоимости полимера .Thus, by reducing the consumption of catalyst at a given performance of the polymerization battery, a reduction in the cost of the polymer is achieved.
