Abstract
A method of evaluating formation of fouling material in a petroleum feed involves illuminating a sample with cross-polarized light while subjecting the sample to temperature and pressure conditions relevant to an industrial process to induce chemical and/or physical changes; collecting images of the treated sample; and analyzing the images to evaluate fouling formation based on heterogeneity of the images in terms of brightness and/or color, where an increase in heterogeneity is indicative of initiation of fouling formation. The method is conducted using a cross-polarized microscopy system including a hot stage reactor assembly capable of withstanding operation within a temperature between about 20° C. to 450° C. or higher, and a pressure between about 0.1 MPa to 16 MPa or higher.
