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;
- and
- controlling a flow of the magnetorheological slurry through the hydrocarbon pipeline, wherein controlling the flow of the magnetorheological slurry through the hydrocarbon pipeline comprises rotationally flowing the hydrocarbons and the magnetorheological slurry through a vortex chamber connected to the hydrocarbon pipeline, wherein the rotational flowing separates the hydrocarbons from the magnetorheological slurry.
