How to adjust when the feed composition of the reformed oil separation tower becomes heavier

Thread Content

I am an operator in the plant; the reformate separation tower in our facility normally receives two feed streams – one is pure C8, and the other is material that has gone through a four-stage process. 17% of the components are non-aromatic, about 20% are C7, around 20% are C8, with the remaining being heavier C9+ compounds. The top of the tower is used primarily for separating components above C7. As a result of adjustments to the equipment, the original amount of 100 T of quadruple material and 6.5 T of C8 has been changed to 130 T of quadruple material and 20 T of C8. It seems that the composition of the components has become heavier compared to the distillation section; however, due to the increase in C8, the C9+ compounds in the stripping section appear lighter. I would like to ask everyone how this situation can be adjusted – is it necessary to increase the reflux ratio? How will the temperature of the sensitive plate in the stripping section change?
