Asphaltene deposition in producing wells, pipelines, and surface facilities leads to detrimental production and operational problems with great economic impact
This review describes how electric properties of asphaltenes and their behavior in an electric field are related to the above-mentioned process parameters
The results revealed that an increase in temperature results in an increase in electrical conductivity
Summary
Asphaltene deposition in producing wells, pipelines, and surface facilities leads to detrimental production and operational problems with great economic impact. In an asphaltene electrodeposition process, an electric field is applied to an electrode material placed in the crude oil. The electric field affects the molecular interactions within crude oil components and destabilizes the hydrocarbon system. This makes it difficult to predict whether the electrodeposition will take place on the cathode or the anode, and which process parameters should be chosen to obtain controlled deposition.
