What does it indicate about the separation efficiency if the temperature of the sensitive plate in the distillation column is too high or too low? Which variables should be changed to adjust it to normal?
If the temperature of the sensitive plate is high, the content of heavy components at the top of the tower increases; if the product meets the specifications, then the reflux ratio should be increased. If the temperature of the sensitive plate is low, the content of light components at the bottom of the tower increases. First, it is necessary to examine the difference between the feed composition and the designed composition; if the difference is not significant, then the reflux ratio and reboiling conditions should be adjusted
If the temperature of the sensitive plate is too high, the heavy components at the top of the tower are likely to exceed the specified limits; if the temperature is too low, the light components at the bottom of the tower are likely to exceed those limits
