The solvent oil produced from the side line of the solvent oil unit is qualified even though the reboiler at the bottom of the side line tower is not in use. What's going on?

The original design is that the oil produced from the side line first enters the side line tower to evaporate the light components (the side line stripping tower uses the reboiler at the bottom of the tower to provide heat), so that its initial distillation point reaches the requirement. The current production situation is that the side stream bottom reboiler is not in use, but the side stream products are qualified. Excuse me, why is this? What's wrong with this? How to transform it?
Maybe it turns out that the accuracy is relatively high, and it only needs to meet the requirements. This will also reduce operations and save costs.
Is the temperature of the fractionating tower too high?
The fractionation tower has a better fractionation effect and can stop the heat source of the reboiler of the side column tower, which is more conducive to energy saving.
The feed temperature is too high, or the top reflux is too large, the middle reflux is small, and the heat extraction is unreasonable.
I'm not a newbie in this field, so I'll give you a thumbs up:(
