Initial distillation and 90% point
Thread Content
The initial boiling point of gasoline is 38, which is normal, while the 90% boiling point is unstable, sometimes around 140 and at other times around 170. I would like to ask the experts what causes this
It’s determined by the properties of the raw materials. What kind of equipment do you have?
Is three-stage reflux appropriate? Are the temperature settings for the three stages reasonable? If stability is to be maintained at all times, it is necessary to consider whether the properties of the raw materials have changed!
Is it normal that the raw material refining process is separated? Can the butadiene content reach the designed value?
