Description

антраценовой фракции, поступает на регул тор 6, где он сравниваетс  с заданием, и при наличии рассогласовани  отрабатываетс  регулирующее воздействие на расход антраценовой фракции. Одновременно производитс  коррекци  регулировани  расхода антраценовой фракции по количеству отбора антраценовой ф|ракции, замеренного датчиком 7.anthracene fraction, is fed to the controller 6, where it is compared with the task, and if there is a mismatch, the regulating effect on the consumption of the anthracene fraction is worked out. At the same time, the adjustment of the consumption of the anthracene fraction by the amount of sampling of the anthracene fraction measured by sensor 7 is made.

Выходной сигнал вычислительного устройства 4, пропорциональный показателю качества антраценовой фракции (количество отгона 300-360°С), поступает на регул тор 8, где сравниваетс  с заданием, и при наличии рассогласовани  отрабатываетс  регулирующее воздействие на изменение количества орошени . Одновременно производитс  коррекци  расхода орошени  но температуре антраценовой фракции на тарелке отбора фракции, замеренной датчиком 9.The output signal of the computing device 4, which is proportional to the quality indicator of the anthracene fraction (the amount of distillation is 300-360 ° C), is fed to the controller 8, where it is compared with the task, and if there is a mismatch, the regulating effect on the change in the amount of irrigation is processed. At the same time, a correction is made of the flow rate at the temperature of the anthracene fraction on the sampling plate of the fraction measured by sensor 9.
