Crude oil blending to reduce organic-based fouling of pre-heat train exchangers and furnaces

USPTO Application #: 20080047874
Title: Crude oil blending to reduce organic-based fouling of pre-heat train exchangers and furnaces
Abstract: A high solvent power (HSP) crude oil is added to a blend of incompatible oils to proactively address the potential for fouling heat exchange equipment. The HSP component dissolves asphaltene precipitates before coking affects heat exchange surfaces. An HSP 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.
