A method and apparatus for processing a hydrocarbon stream are described. The method includes heating a feed stream in a convective bank. The heated feed stream is reacted in a first reaction zone to form a first effluent, which is heated in a first radiant cell. The first radiant cell combusts fuel to heat the first effluent and forms a first exhaust gas. The first exhaust gas is contacted with the convective bank to heat the feed stream. The outlet temperature the heated feed stream from the convective bank is controlled by introducing an additional gas stream into the convective bank. There can be additional reaction zones and radiant heaters.

Reforming process with improved heater integration

An apparatus for a fired heater is presented. The fired heater is designed with process coils inside a shell, and with a positioning of the burners for reducing the size of the fired heater. The shell has a general rectangular prismatic shape with combustion inlets for admitting combustion gases from the burners, and the process coils include at least two inlet ports and at least one outlet port.

Process fired heater configuration

A process is presented for the dehydrogenation of paraffins. The process utilizes heated air for the combustion of a fuel within the dehydrogenation reactor to provide the heat of reaction for oxidative dehydrogenation. The nitrogen in the air is utilized as a diluent. A paraffin feedstream is mixed with a fuel, and the fuel/paraffin feedstream is mixed with an oxidant air stream at the inlet of dehydrogenation reactor.
