Diesel 95. How is the quality controlled for the initial boiling point of light naphtha and the dry point of heavy naphtha?
Diesel controls the distillation outlet temperature, while naphtha controls the tower top temperature.
For diesel 95, it is controlled by the extraction volume and extraction temperature; for light stone, the initial boiling point needs to be properly managed to ensure that the C5 content in the liquefied gas is not too low, while for heavy stone, the dry point is primarily controlled by the reflux rate from the distillation column
