ABSTRACT:
A heat exchange method and flow control system for a hydrocarbon conversion process having two reactors in series which allows efficient heat recovery and effective process control under widely varying process conditions. The hydrocarbon feed stream is divided into three streams. In the preferred embodiment, the first stream is not heat exchanged and is controlled along with the preheater heat supply by a split range controller activated in response to the temperature of the stream entering the first reactor. The second stream is heat exchanged with the effluent of the first reactor and flows at a rate controlled by its temperature after this heat exchange. The third stream is heat exchanged with the effluent of the second reactor and flows at a rate such that the total of all three streams is the desired capacity for the unit. A hydrogen recycle stream is proportionally divided between the second and third streams by a ratio control means. the second stream is combined with the third stream and passed into a preheater. The first stream is then admixed with the effluent of the preheater to form the stream fed to the first reactor.
