Abstract
A high solvency dispersive power (HSDP) crude oil is added to a blend of 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. An HSDP oil is also flushed through heat exchange equipment to remove any deposits and/or precipitates on a regular maintenance schedule before coking can affect heat exchange surfaces.
