Claim:
1. A method to continuously clean a fouled process stream using a magnetic field, the method comprising the steps of: feeding the fouled process stream to a magnetic separation unit, the fouled process stream comprising a fouling constituent, the magnetic separation unit comprising: a separation vessel, the separation vessel configured to receive the fouled process stream, the separation vessel having a body with an external surface, the body defining an interior cavity; a mounted magnet partially adjacent to the separation vessel, the mounted magnet configured to generate the magnetic field, the magnetic field operable to reduce a concentration of the fouling constituent, the mounted magnet comprising: a circulation pump fluidly connected to the separation vessel, the circulation pump configured to receive a circulation feed from the separation vessel to produce a circulation return, wherein the circulation return is recycled to the separation vessel; and a sampling point fluidly connected to the separation vessel, the sampling point configured to allow removal of a sample; measuring the concentration of the fouling constituent in the sample; and supplying an effluent stream from the separation vessel to a clean collection vessel when the concentration of the fouling constituent in the sample is below a target concentration.
