ABSTRACT:
Samples of a petroleum oil stream (e.g. crude oil feed stream to a refinery) are continually monitored to determine incompatible asphaltenes therein and the rate of antifoulant is adjusted in response to changes in the level of incompatible asphaltenes. The method of the present invention employs thin layer chromatographic films for separating incompatible asphaltenes and for measuring an optical property indicative of the incompatible asphaltenes, and for varying antifoulant addition in response to changes of the optical property measured.
