Abstract

The analysis of the structure and chemistry of deposits formed by the crude oil fouling process is paramount in gaining an understanding of the underlying causes and mechanisms. Chapter 4 begins with a review of industrial practice and findings in this context and suggests recommended practice for the collection, preparation, and analysis of refinery samples. The second part of this chapter discusses more advanced techniques for the determination of the chemical structure and molecular weight of deposits and the third part of Chapter 4 introduces a novel technique (. chemical imaging) by which the location of various chemical species in a surface layer can be established. The final part of Chapter 4 gives a description of a fluid dynamic gauging technique developed for measuring the thickness and strength of deposits in situ, in real time, and in a liquid environment.
