    摘要: 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.

    摘要: Method and system for predicting a need for introducing anti-fouling additives to a hydrocarbon stream in a hydrocarbon refinery. The method comprises characterizing whether the hydrocarbon stream is a non-high solvency dispersive power (“HSDP”) crude and performing at least one of determining whether the hydrocarbon stream is subject to filterable solids levels greater than about 100 wppm or classifying whether the hydrocarbon stream has an expected low flow velocity during normal operating conditions within the refinery. The method further comprises indicating, using a processor, that anti-fouling additives are recommended if the hydrocarbon stream is characterized to be a non-HSDP crude and either the hydrocarbon stream is determined to be subject to filterable solids levels greater than about 100 wppm or the hydrocarbon stream is classified as having expected low flow within a heat exchanger of the refinery.

    摘要: 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.

    摘要: A high solvency dispersive power (HSDP) crude oil is added to a blend of incompatible and/or near-incompatible oils to proactively address the potential for fouling heat exchange equipment. The HSDP component dissolves asphaltene precipitates and maintains suspension of inorganic particulates before coking affects heat exchange surfaces. HSDP co-blending for fouling mitigation and on-line cleaning can be affected using different concentrations of top-performing and moderate-performing HSDP crude oils.
