METHOD FOR ON-LINE DECOKING OF FLAME CRACKING REACTORS

摘要

- 26 -METHOD FOR ON-LINE DECOKINGOF FLAME CRACKING REACTORSABSTRACTThis invention relates to a method foron-line decoking of flame-crackinq reactors wherebydecoking is achieved without interruption of thenormal operation of such reactors and without thenecessity to change feed equipment and/ordisassemble reactor components. While maintainingthe temperature of the effluent at 1000°C to 2000°C,the flow of the hydrocarbon feedstock in the reactoris periodically stopped for a time sufficient toreduce the carbon deposits to an acceptable level.
