Изобретение относитс к .способам регулировани ректификациОНных колонн, предназначенных дл разделени жидких миогокомпонентных смесей гаа отдельные фракции, и может примен тьс в химической и нефтехимической промышленности.The invention relates to methods for adjusting distillation columns for the separation of liquid myocomponent mixtures for individual fractions, and can be used in the chemical and petrochemical industries.
Известен способ автоматического регулиро1вани процесса ректификации путем изменени оодачи теплоносител в зависимости от температуры на контрольной тарелке. Однако указанный способ не обеспечивает высокого качества целевого продукта.There is a known method for automatic control of the rectification process by changing the coolant supply depending on the temperature on the control plate. However, this method does not provide the high quality of the target product.
Дл повышени качества целевого продукта предлагаетс подачу теплоносител корректировать по скорости изменени температуры в зоне ввода сырь .To improve the quality of the target product, it is proposed to adjust the flow of heat transfer medium according to the rate of temperature change in the zone of input of raw materials.
На чертеже показана схема реализации описываемого способа.The drawing shows the implementation of the described method.
Количество тепла, вводимого в колонну 1, регулируетс подводом теплоносител в кип тильник 2 по температуре на контрольной тарелке , соот.ветствуюш,ей заданному качеству целевого продукта и замер емой термопарой 3, сигнал с которой поступает на преобразователь напр жени 4, а затем - на электропневмопреобразователь 5. Выходной сипеал подаетс в регулируюпдий блок 6 и сравниваетс с заданным значением температуры. Выход с регул тора идет на исполнительный механизм 7, управл юш,ий подводом теплоносител .The amount of heat introduced into column 1 is regulated by supplying the coolant to boiler 2 according to the temperature on the control plate, corresponding to its target product quality and measured by thermocouple 3, the signal from which is fed to the voltage converter 4, and then to an electropneumatic transducer 5. The output sepeal is fed to the regulator unit 6 and is compared with a predetermined temperature value. The output from the regulator goes to the actuator 7, which controls the supply of heat-transfer agent.
При ивмененип теплосодержани сырьевой смеси, вызванном изменением степени подогрева или состава сырь , изман етс температура в зоне ввода питани , замер ема скоростной термопарой 8, сигнал с которойIn case of heat content of the raw material mixture, caused by a change in the degree of heating or the composition of the raw material, the temperature in the feed-in zone is measured, measured by a high-speed thermocouple 8, the signal from which
проходит через блоки регулируюш,ей цепи и корректирует подачу теплоносител . Корректпруюпдий свгнал действует до тех пор, пока не стабилизируетс в зоне ввода питани , после чего количество вводимого теплоноснтел определ етс только температурой на контрольной тарелке.passes through the blocks, adjusts its chains and corrects the flow of coolant. The correction valve operates until it is stabilized in the feed-in zone, after which the amount of input coolant is determined only by the temperature on the control plate.
Предмет изобретени Subject invention
Способ автоматического регулировани процесса ректификации путем изменени подачи теплоносипгел в зависимости от температуры на контрольной тарелке, отличающийс тем, что, с целью повышени качества целевого продукта, подачу теплоносител корректируют по скорости изменени температуры в зоне ввода сырь .A method of automatically adjusting the distillation process by changing the supply of heat transfer gel depending on the temperature on the control plate, characterized in that, in order to improve the quality of the target product, the flow of heat transfer medium is adjusted by the rate of temperature change in the feed zone.
