Summary:PROBLEM TO BE SOLVED: To provide a method for mitigating the fouling in process equipment due to thermally cracked oils.SOLUTION: This invention relates to a method or the like for mitigating the fouling in the process equipment by thermally cracked oils with diene values by UOP method number 326-82 of 4 grams iodine/100 grams oil or greater, wherein the thermally cracked petroleum oils come from a thermally cracking equipment. In the process equipment provided downstream of the thermally cracking equipment and having residence time of more than 30 seconds, the temperature of the thermally cracked oils is kept in a temperature range of 580 to 650°F (304 to 343°C).
