Description
(54) СПОСОБ РЕГУЛИРОВАНИЯ ПРОЦЕССА ПОЛИМЕРИЗАЦИИ(54) METHOD OF REGULATING THE POLYMERIZATION PROCESS
переходных процессов дл концентрации катализатора в реакторе при qo 2xu и (х - текуща концентраци катализатора в реакторе, t - врем , а - коэффициеит нагрузки реактора).transients for the concentration of catalyst in the reactor at qo 2xu and (x is the current concentration of catalyst in the reactor, t is the time, and is the coefficient of the reactor load).
По приведенным кривым наход т, что врем выдержки регулирующего воздействи , до переключени его, дл qo 2xo и q(i 0, равно 15 м.ин. Таким образом, переключение с воздействи qo 2x. (двойное воздействие па входе в реактор) на ,2xo, а также с qo 0 (нулевое воздействие на входе в объект - «обратное двойное воздействие) на q,,0,8xc. осун1,ествл етс через 15 мин.According to the curves, it is found that the exposure time of the regulating action, before switching it over, for qo 2xo and q (i 0 is equal to 15 min.). Thus, switching from the influence of qo 2x. (Double effect on the reactor inlet) 2xo, as well as with qo 0 (zero impact on the entrance to the object - "reverse double impact) on q ,, 0.8xc. Base 1, takes 15 minutes.
Предмет изобретени Subject invention
Снособ регулировани процесса полимеризации с перемеиным регулирующим воздействием путем изменени концентрации катализатора на посто нную долю от величины исходного регулирующего воздействи в реакторе, отличающийс тем, что, с целью обеспечени инвариантности и минимальности времени переключени , измен ют вначале регулирующее воздействие на равную себе величину с последующим переходом через посто нное врем на заданное регулирующее воздействие, соответствующее новому состо нию реактора.A method of controlling the polymerization process with a variable regulatory effect by changing the catalyst concentration to a constant fraction of the value of the initial regulatory effect in the reactor, characterized in that, in order to ensure invariance and minimal switching time, the regulating effect is changed to an equal value with subsequent transition after a constant time at a given regulatory action corresponding to the new state of the reactor.
