Abstract:

Heat-induced deposition and coke formation results in fouling which leads to down time and economic loss. If severe pyrolysis occurs, the intermediate polarity material is ruined. This can result in both heat-induced deposition and coking.  The common prevention measure is halting distillation early enough so that coke doesn’t form. This lack of an indicator results in premature cessation which is inefficient. A proper index of pyrolytic processes can be established using the Automated Flocculation Titrimeter (AFT). The AFT performs Heithaus titration based on ASTM D 6307. The instrument accurately predicts the compatibility of asphalts, petroleum residues, and heavy oils. The parameters set forth by the results provide the basis for the process’s retention time. Western Research Institute established the WRI Coking Index, allowing the danger of pyrolysis to be measured. The WRI index is used to indicate the proximity to coke formation. The prevention of undesirable coke and heat-induced deposition minimizes fouling and increases efficiency. The poster discusses the applications of the AFT instrument for diminishing fouling caused by heat-induced deposition and coke formation.
