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 value indicative of the fouling propensity at no less than two different temperatures, and an activation energy of fouling by the hydrocarbon stream is derived therefrom. In another method, the thus obtained parameter value at no less than two different temperatures and the activation energy are used to select proper heating fluids and operating temperature and to determine whether to add an antifoulant to the hydrocarbon stream to reduce fouling at a given temperature.
