Изобретение относитс  к автоматизации процессов полимеризации и може быть использовано в производстве синтетического каучука.This invention relates to the automation of polymerization processes and can be used in the production of synthetic rubber.

Известен способ управлени  непрерывным процессом полимеризации, осуществл емым в батарее реакторов, заключающийс  в изменении расхода катализатора в зависимости от перепада давлени  на реакторах батареи или мощности, потребл емой мешалкой одного из реакторов 1 j .A known method of controlling the continuous polymerization process carried out in a reactor battery is to vary the catalyst consumption depending on the pressure drop across the battery reactors or the power consumed by the agitator of one of the 1 j reactors.

Недостатками способа  вл ютс  низка  точность, невысокое качество стабилизации в зкости по Муни полимера . Обусловлено это значительным запаздыванием в системе регулировани  в случае подачи катализатора в зависимости от в зкос и полимеризата , конверсии мономера, температуры полимеризации, вли ни  степени забивки реактора на мощность, потребл емую маиалкой, состо ни  сальникового уплотнени  и т.п.The disadvantages of the method are low accuracy, low quality of Mooney polymer viscosity stabilization. This is due to a significant delay in the control system in the case of catalyst supply depending on oil and polymer, monomer conversion, polymerization temperature, the effect of the degree of clogging of the reactor on the power consumed by mayalkoy, stuffing box, etc.

Целью изобретени   вл етс  повышение точности стабилизации в зкости по Муни каучука.The aim of the invention is to improve the accuracy of the stabilization of Mooney rubber viscosity.

.Эта цель достигаетс  тем, что в известном способе управлени  непрерывным процессом полимеризации, осуществл емым в батарее реакторов, заключающемс  в изменении расхода катализатора в зависимости от перепада давлени  на реакторах батареи или мощности, потребл емой мешалкой одного из реакторов, корректируют величину перепада давлени  на реакторах батареи или мощности, потребл емой мешалкой одного из реакторов, в зависимости одновременно от концентрации полимера в процессе полимеризации и в зкости полимеризата в одном из первых реакторов батареи реакторов.This goal is achieved by the fact that in a known method of controlling a continuous polymerization process carried out in a reactor battery, which consists in changing the catalyst consumption depending on the pressure drop across battery reactors or the power consumed by the stirrer of one of the reactors, the pressure drop across the reactors battery or power consumed by the stirrer of one of the reactors, depending simultaneously on the concentration of the polymer in the polymerization process and the viscosity of the polymer in one of the first factors of the reactor battery.

На чертеже представлена блок-схема системы регулировани  дл.г: реализации предлагаемого способа.The drawing shows a block diagram of the regulation system for the year: the implementation of the proposed method.

Исходные продукты процесса полимеризации - мономер (бутадиен) и растворитель (толуол), предварительно охлажденные , непрерывно подают на входThe initial products of the polymerization process - monomer (butadiene) and solvent (toluene), pre-cooled, continuously fed to the input

смесител  1, а затем - на полимеризационную батарею в реакторы 2 и 3. в реактор 2 поступает дополнительный растворитель дл  поддержани  в нем заданного температурного режима.mixer 1, and then to the polymerization battery in reactors 2 and 3. Additional solvent enters reactor 2 to maintain the desired temperature in it.

Процесс осуществл ют в присутствии комплексного катализатора, состо щего из галогенидов титана и триизобутилалюмини , в полимеризационной.,батареThe process is carried out in the presence of a complex catalyst consisting of titanium halides and triisobutylaluminum, in a polymerization. Battery.
