How is internal circulation in a gasoline-diesel plus distillation double tower established? ? ?
Thread Content
I would like to ask fellow users: while dealing with the production reduction caused by faults in the gasoline/diesel combustion reaction system! The internal circulation of the two distillation towers needs to be modified for fractional distillation, and heat for distillation must be maintained until operation begins. Specifically, how should the internal circulation of these two towers be altered? Do the reflux pumps of the stripping tower and distillation tower still need to be running? Additionally, if a single-tower cycle is required, what kind of single-tower process would that be? Thank you for the advice! ! !
It is to truncate the low-boiling fraction and feed it into the distillation process after modifying the reaction cycle! Before the outlet of the bottom oil from the fractionation tower, the circulation line is shortened and routed back to the stripping tower, allowing circulation between the two towers
But the question is, does the dual-loop reflux still need to be turned on?
