Abstract: Methods for determining the fouling propensity of a hydrocarbon stream and for reducing fouling are provided. In one method, the fouling propensity of a hydrocarbon stream is determined by obtaining a parameter indicative of the fouling propensity by a regression of a series of temperature measurements data for the hydrocarbon stream exiting a test unit. In another method, an effective minimal amount of an antifoulant is added to a hydrocarbon stream to reduce fouling, where the amount of the antifoulant is determined based on the fouling propensity of the hydrocarbon stream.

Abstract: A method for reducing the formation of deposits on the inner walls of a tubular heat exchanger through which a petroleum-based liquid is flowing comprises applying one of fluid pressure pulsations to the liquid flowing through the tubes of the exchanger and vibration to the heat exchanger to effect a reduction of the viscous boundary layer adjacent the inner walls of the tubular heat exchange surfaces. Reduction of the viscous boundary layer at the tube walls not only reduces the incidence of fouling with its consequential beneficial effect on equipment life but it also has the desirable effect of promoting heat transfer from the tube wall to the liquid in the tubes. Fouling and corrosion are further reduced by the use of a coating on the inner wall surfaces of the exchanger tubes.

Abstract: A method for the on-line cleaning of a heat exchanger used with petroleum process fluids which create coke deposits of asphaltenic origin on the exchanger tubes. The asphaltenes are removed by re-dissolution in a solvent oil of high solubility power for the asphaltenes. Certain asphaltenic crudes are useful as solvents in view of their chemical similarity to the asphaltene coke precursors; also useful are refined petroleum fractions such as gas oils which are also characterized by their solvency for asphaltenes. The solvent oil may be admitted to the heat exchanger following withdrawal of the process fluid and then allowed to soak and dissolve the asphaltene coke precursors after which the resulting solution may be withdrawn and the exchanger returned to use without being at any time disconnected from its associated process unit.
