Placed after the reactor, is there another reactor behind it? If it exists, it’s a pretreatment reactor; if not, I’m not sure. Could it be a distillation reaction?

It would be best to upload the flowchart so that everyone can help analyze it

The reason is to exchange heat with the feed in order to bring it to the reaction temperature

Due to the high price of bromine as a raw material, direct feeding into the heating furnace can lead to coking. Saturation of the olefins is achieved in a first reaction stage; thereafter, the mixture is fed into the heating furnace to exchange heat with the feed material, before proceeding to a second hydrogenation stage
