Relationship between the extraction temperature of the fractionation tower and the boiling range temperature
Thread Content
For example, in a coking distillation tower, the diesel extraction temperature is 240, with a boiling range of 170–370； For the atmospheric distillation column in the vacuum distillation unit, the extraction temperature for line 1 is 177, and the extraction temperature for line 2 is 264; the boiling range is 170–330 ； I’m stuck in a dead end; I can’t find a way out. Could any experienced person help me?
Boiling points vary with pressure; composition also differs, with Chushan having a higher proportion of straight-chain hydrocarbons
Due to differences in oil and gas composition, their partial pressures vary, which in turn results in different boiling points or distillation temperatures.
The extraction temperature should be related to the initial boiling point of that fraction and the final boiling point of the slightly lighter fractions above it
The extraction temperature is high, and the diesel boiling range is wide; in other words, the diesel produced is of higher quality! :)
