A method for improving the efficiency of a fired heater without an air preheat system is described. The method involves the use of an additional outboard convection section which is separate from the regular convection section of the fired heater. The outboard convection section uses the boiler feed water or an alternate cold sink to reduce the temperature of the flue gas, thereby improving the efficiency.

Method of efficiency enhancement of fired heaters without air preheat systems

Processes and apparatuses for relocating a reforming process heater service into the convection section rely on combining a flue gas recycle quench stream with the radiant section off gases entering the convection section. The uniformity of mixing influences the effectiveness of that quench stream. The more effective the quench stream is, the lower the equipment size required to manage the recycle design.

A fired heater has two cells segregated by an insulative wall. A first plurality of burners are located in the first cell and a second plurality of burners are located in the second cell. A radiant tube extends from the first cell to the second cell for carrying a fluid material through the heater to heat the fluid material. The flow of fuel to the burners in either the first cell or the second cell can be terminated to accommodate lower heater duty when demand is lower.

A regeneration process for olefin cracking reactor is presented. The process utilizes the nitrogen waste stream from an air separation plant and the partially combusted effluent stream from the olefin cracking reactor is used to heat the nitrogen waste stream. The control of the heating of the nitrogen waste stream can be achieved through redirection of a portion of the heat from combustion to generate steam.
