Abstract: 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.

Abstract: Methods and apparatus for removing deposits from a petroleum flow line are disclosed. An example of one method includes generating an electric wave that includes a high frequency component having a high frequency in a range from approximately 25 kHz to approximately 65 kHz. The method further includes applying the electric wave to at least two field windings circumferentially disposed around a petroleum pipe while a petroleum fluid is flowing in the petroleum pipe. The method also includes generating, in response to the applied electric wave, magnetic fields in the at least two field windings. The magnetic fields in the at least two field windings can have magnetic axes that are not collinear with respect to each other.
