What to do if the light component content in Changsan line oil is high?

The light components in the normal pressure column’s third fraction are abundant, including diesel components. No matter how it’s adjusted, it doesn’t work. Is there any way? Blowing superheated steam into the stripper doesn’t work
The constant third stream should be designed to consist of heavy diesel components; if there is a high proportion of diesel components in this stream, it is recommended to consider using distillate diesel, along with adopting a \"deeper extraction\" approach in the vacuum distillation tower.
At normal pressure, the temperature of the second distillate can be increased, thereby raising the dry point of diesel appropriately.
1. Reduce the reflux at the lower part of the third line and increase the reflux at the upper part. 2. Raise the temperature at the furnace outlet. 3. Inspect the internal components of the tower
