A method for installing a device into a crude oil service operation, the method may include installing the device into a section of the crude oil service operation, wherein the device comprises a surface comprising a Self-Assembled Monolayer of Phosphonate (SAMP) coating, and may also include contacting the surface with the contaminant, wherein the contaminant is selected from the group consisting of paraffins and asphaltenes. Various systems include one having a liquid environment of paraffins and asphaltene, and a surface residing within the environment comprising a Self-Assembled Monolayer of Phosphonate (SAMP) composition. Systems also include pipelines and vessels having an internal surface therein comprising a Self-Assembled Monolayer of Phosphonate (SAMP) composition, and with hydrocarbon liquids present in the pipeline or vessel.

A method for installing a device into a crude oil service operation, the method may include installing the device into a section of the crude oil service operation, wherein the device comprises a surface comprising a monolayer coating, and may also include contacting the surface with the contaminant, wherein the contaminant is selected from the group consisting of paraffins and asphaltenes. Various systems include one having a liquid environment of paraffins and asphaltene, and a surface residing within the environment comprising a monolayer composition. Systems also include pipelines and vessels having an internal surface therein comprising a monolayer composition, and with hydrocarbon liquids present in the pipeline or vessel.

Methods for precipitating solids comprising asphaltenes and/or paraffins that may include precipitating the solid and contacting the solid with a surface comprising a monolayer coating or alternatively may include precipitating the solid in the presence of such a surface. The method for treating a liquid containing contaminants comprising asphaltenes and/or paraffins may include inserting into the liquid, a surface as described above, or further coating surfaces within the liquid with a monolayer coating.
