Abstract

Heat exchangers of CDU in Dung Quat Refinery are frequently fouling. The study and use of chemicals for fouling treatment are of great economic significance for the refinery. This paper briefly introduces the fouling phenomenon, the economic effects of fouling in refineries, and current anti-fouling treatment in Dung Quat Refinery. The authors evaluated the deposit properties and prepared suitable chemical for fouling treatment. The results show that there are about 40 - 60% of CCR deposit and 20 - 40% of paraffin in the fouling deposit, which has a C/H ratio of 5 - 7. The produced chemical has a diesel oil/turpentine/surfactant/amine ratio of 37.2/55.6/1.8/5.4 and a chemical/deposit weight ratio of 8. The solution after fouling treatment is suitable for use as furnace fuel.
