摘要： In a steam cracking operation the formation of coke is a problem which needs to be overcome. While significant work has been done on decoking of furnaces little work has been done regarding transfer line exchangers. Coking of transfer line exchangers (TLE) may be reduced by injection of a solution containing at least one group 1 or 2 metal dichromate or dichromate and one or more of a group 1, 2 or 7 metal carbonate into the TLE.
