Abstract (en)

[origin: WO9620256A1] A steam cracking method and plant using erosive powder injection for at least partially decoking quenching exchangers without breaking the steam cracking cycle. The powders are preferably injected slightly upstream from the quenching exchangers (4) or (TLE) and separated from the cracked gases in primary gas/solid separators (5), temporarily stored in temperature-controlled collecting tanks, and delivered to a common powder storage and/or processing module by pressure transfer using a relatively small flow of non-condensable gas. The method and plant may be used to collect solid fragments generated by the injection of chemical compounds used as catalysts for the steam gasification of coke.
