FIELD: technological processes.
SUBSTANCE: invention relates totool for processing of hydrocarbon flow. Method includes heating of feed stream in convection block. Heated feed stream is reacted in the first reaction zone to form a first effluent which is heated in the first radiating chamber. In the first radiating chamber fuel is burnt for heating of the first outlet flow and the first spent gas is formed. First exhaust gas is brought into contact with convection unit to heat feed stream. Temperature of the heated feed stream at the outlet of the convection block is controlled by introducing an additional gas flow into the convection block. Additional reaction zone and radiating heaters may be present. Invention also relates to a device for processing hydrocarbon flow.
EFFECT: reduced fuel consumption for zones of radiative fire heating and efficient temperature control at the output of the first reactor.
