摘要
Hydrocarbon vapocracking installation comprising at least one hydrocarbon cracking furnace, an indirect quenching exchanger for the effluents coming out of the furnace, direct quenching means for those effluents and means (36, 38) for injecting the erosive solid particles into the plant for the decoking thereof, as well as a cyclone (10) placed at the out end of the indirect quenching exchanger to separate the solid particles from the gas effluents, the outlet (14) for the solids of the cyclone being connected to storage tanks (22, 30) arranged in series with insulating valves (16, 28, 34), a pressure gas source (38) being provided to raise the pressure in one of the tanks and inject the solid particles into the plant.
