Examples of methods and apparatus for reducing deposits from a petroleum flow line may include a pipe capable of being attached to a petroleum flow line. The pipe may have a pipe axis that defines a direction for fluid flow in the petroleum flow line. The apparatus may also include a first and a second field winding circumferentially disposed around the pipe, and an electric wave generator adapted to electrically communicate an electric wave to the first field winding and the second field winding. In response to the electric wave, the first and the second field windings are adapted to produce magnetic fields having a first magnetic axis a second magnetic axis, respectively. The first magnetic axis may be noncollinear with respect to the second magnetic axis, and at least the first magnetic axis may be noncollinear with respect to the pipe axis. |
