Description
II
Известен способ управлени процессом полимеризации , например, в производстве каучука СКД, путем стабилизации свойств полимера изменением перепада давлени на отдельных участках процесса.There is a known method for controlling the polymerization process, for example, in the production of SKD rubber, by stabilizing the properties of the polymer by changing the pressure drop in certain parts of the process.
С целью повышени степени стабилизации свойств полимера, например его в зкости по Муни, измер ют концентрацию полимера в полимеризаторе и при отклонении ее от заданного значени измер ют cтaбилизиpJeмyю величину перепада давлени .In order to increase the degree of stabilization of polymer properties, for example, its Mooney viscosity, the polymer concentration in the polymerizer is measured, and when it deviates from a predetermined value, the stability of the pressure differential is measured.
По предлагаемому способу непрерывно измер ют величину концентрации полимера в полимеризате и, зна зависимость междз этой концентрацией и перепадом давлени на участке полимеризационкой батареи или давлением шихты на входе в батарею, с изменением концентрации полимера измен ют на соответствующую величину стабилизированное значение перепада давлени на участке полимеризационной батареи или давление шихты на входе в батарею.According to the proposed method, the polymer concentration in the polymer is continuously measured and, depending on this concentration and the pressure drop over the polymerization section of the battery or the charge pressure at the inlet to the battery, with a change in the polymer concentration, the stabilized value of the pressure differential across the section of the polymerization battery or charge pressure at the inlet to the battery.
Предлагаемый способ иллюстрируетс чертежом .The proposed method is illustrated in the drawing.
Величина перепада давлени непрерывно измер етс на участке между полимеризаторами J и 2 датчиком ДП. При изменении величины этого перепада, что свидетельствует об изменении в зкости при неизменной концентрации полимера в полимеризате, регул тор РП, воздейству на исполнительный механизмThe pressure drop is measured continuously between the polymerization agents J and 2 with the DP sensor. When the magnitude of this difference changes, which indicates a change in viscosity at a constant polymer concentration in the polymerizate, the regulator of the RP affects the actuator
дозируюшего насоса ДН, измен ет подачу катализатора.metering pump DN, changes the catalyst supply.
Датчик ДК одновременно непрерывно измер ет концентрацию полимера в полимеризате и с изменением этой концентрации регул торThe DK sensor simultaneously continuously measures the concentration of the polymer in the polymer and with the change of this concentration the regulator
РК осуществл ет коррекцию стабилизируемой величины перепада давлени в регул торе РП на величину, соответствующую изменению этой концентрации.The RK carries out the correction of the stabilized value of the pressure drop in the RP regulator by an amount corresponding to a change in this concentration.
