摘要: The present invention provides a process to treat steels, preferably carbon steel to reduce the tendency of the steel to form coke when in contact with hydrocarbons at elevated temperatures. The steel may be first reduced then treated with a mixture of compounds which further modify the reduced surface and finally the treated steel surface is cured. The treated steel has a reduced propensity to form coke when in contact with hydrocarbons particularly at higher temperatures.

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.
