The hydrocracking unit’s fractionation tower is equipped with a heavy stone-side steam stripping column; anyone with experience with such installations? Let’s exchange information!

It’s not necessary; the downstream reforming unit has a pull-out unit

The large hydrocracking unit at Zhejiang Petrochemical seems to be set up in this way.
The heavy stone side line is designed to extract the heavy stones in order to provide high-quality raw materials for reforming. This side line is affected by many factors at the upper part of the distillation tower, making it difficult to operate; therefore, our current process includes such a heavy stone side line
