Middle distillation range

Which buddy has tested the boiling range of catalytic fractionation No. 1?
We analyzed the boiling range of Stream 1; its 95% boiling point is around 360. The feed material for the reaction is produced from full-paraffin oil. We also carried out a technical modification in which part of the intermediate oil from Stream 1 was fed together with diesel, as the boiling range of diesel is quite low, with a 95% boiling point of only around 320.
Our one-stage dry point is at 380-390 degrees; the return point of stage one is one layer above the diesel extraction point
I mainly want to know, why are you asking this?
My question is: I’m worried that if the outlet for fraction 1 is too close to the diesel extraction port, fraction 1 might not be properly separated on the tray and end up being extracted through the diesel port. Also, could a too wide boiling range for fraction 1 result in the diesel not meeting quality standards?
The material returned to the tower is the lower layer taken from the side stream; your situation is quite special – aren’t you sure about that?
Can we proceed with shipping the product right now since the fuel is ready? Is quality that important? As long as the diesel can be made available, that’s enough
Normally, no analysis is done on the urging of firewood. .
1. The first mid-return stream in the fractionation tower is located at the layer below that where diesel is extracted; once all the diesel has been extracted, the external reflux from this first mid-return stream is used as the internal reflux for the tower. 2. If the fraction belonging to Grade 1 enters the diesel, it is caused by tower flooding.
