Analyze the reasons for the substandard quality of crude gasoline? How to handle it? Try to analyze various situations – determine how the different types of defects lead to a situation where the front is heavy and the back is light, or vice versa. Points will be given for this! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! Give extra points

Changes in the temperature at the top of the distillation tower, changes in the cold reflux flow rate and the temperature after cooling in the constant circulation system, or water carried in the reflux stream. a. Adjust the flow rate of the cooled liquid, or adjust the cooling effect, as well as the water level in the oil-water separator at the top of the distillation tower. b. Changes in the degree of reaction and the volume of material processed. b. Adjust the operations based on changes in product quality. c. Changes in the reflux flow rate or temperature at intermediate stages, as well as changes in the amount of diesel output from the unit. c. Adjust the reflux flow rate and temperature at intermediate stages, as well as the amount of diesel output from the unit. d. Changes in the steam supply for reactions and distillation processes. d. Adjust the steam supply levels; if there are changes in the total steam pressure, contact the boiler to adjust it. e. Changes in the pressure within the distillation tower. e. Adjust the pressure to maintain stable distillation conditions. f. Blockages in the tray columns, or excessive sticking of floating valves, which affect the efficiency of distillation. f. Adjust the volume of material processed; when there are blockages, the tower can be cleaned. g. Accidents related to cleaning the tower. g. Adjust the volume of material processed, as well as the flow rates of various distillates and reflux streams, along with related parameters
