Abstract
Black powder flowing with hydrocarbons in a hydrocarbon pipeline is converted into a magnetorheological slurry by implementing wet scrubbing in the hydrocarbon pipeline. A flow of the magnetorheological slurry through the hydrocarbon pipeline is controlled.
Claims12
A method comprising:
- converting black powder flowing with hydrocarbons in a hydrocarbon pipeline into a magnetorheological slurry by implementing wet scrubbing in the hydrocarbon pipeline, wherein the black powder comprises magnetic particles;
- separating the magnetorheological slurry from the hydrocarbons resulting in separated magnetorheological slurry and separated hydrocarbons;
- and
- flowing the separated magnetorheological slurry out of the hydrocarbon pipeline by applying a magnetic field to the separated magnetorheological slurry.
