Semi-reg Reforming

Hydrotreated naphtha feed is combined with hydrogen-rich recycle gas, preheated by heat exchange with the reactor effluent and then further heated in a fired heater before entering the first reactor. As the endothermic reforming reactions cool the feed and product mixture, the effluent from the first reactor must be reheated to the required reaction temperature in a fired heater before entering the second reactor, and similarly for the last reactor.
