摘要：
Atmospheric and/or vacuum resid fractions of a high solvency dispersive power (HSDP) crude oil are added to a blend of crude oil to prevent fouling of crude oil refinery equipment and to perform on-line cleaning of fouled refinery equipment. The HSDP resid fractions dissolve asphaltene precipitates and maintain suspension of inorganic particulates before coking affects heat exchange surfaces.
