Abstract (en)
[origin: EP2048217A2] A method for decoking a cracking furnace (1) for the thermal cleavage of hydrocarbons by passing a decoking gas through coked-up plant components with formation of an off-gas (5), involves recycling the off-gas (5) through a cyclone separator (6) into the body of the furnace (1) or subjecting it to a catalytic treatment (11) so as to remove most of the solid particles from the off-gas (5).
