Abstract
Methods and apparatus for improved efficiency and flue gas scrubbing in a fired heater using a condensing convection section. The method preheats a hydrocarbon or hydrocarbon/water process feed stream in a coil in the convection section of a fired heater, collects condensate from the flue gas, and scrubs the flue gas with the recirculated condensate. The apparatus has a heat transfer coil disposed in the convection section, to preheat a process stream and form condensate from the flue gas, and a condensate recirculation loop to collect the condensate from the convection section and scrub the flue gas with the condensate.
