Heated metal surfaces employed in high-temperature refinery heat exchangers, fractionator furnaces, and delayed coker furnaces tend to accumulate thick thermally insulating foulant layers largely composed of metallic sulfides and carbonaceous coke. Such fouling is major industrial problem that results in hundreds of millions of dollars in additional operating costs. To date it is both poorly understood and poorly controlled. We plan to explain the complex corrosion - asphaltene flocculation synergy that results in fouling using a unique analytical approach.

高温炼油厂热交换器、分馏炉和延迟焦化炉中使用的加热金属表面倾向于积累厚厚的隔热污物层，主要由金属硫化物和碳质焦炭组成。这种污染是主要的工业问题，导致数亿美元的额外运营成本。到目前为止，人们对它的了解很少，控制也很差。我们计划使用一种独特的分析方法来解释导致污垢的复杂的腐蚀-沥青质絮凝协同作用。
