DEVICE FOR MAGNETIC TREATMENT OF MOVING OIL-WATER-GAS MIXTURES Russian patent published in 2001 - IPC

FIELD: magnetic activation of liquid media, aqueous systems in particular (suspensions, emulsions, colloidal solutions); oil-and-gas industries for prevention of organic and inorganic deposits on inner surfaces of pump-and-compressor equipment used in treatment of well production and in preparation of water for injection wells. SUBSTANCE: proposed device has hermetic housing made from non-magnetic material with magnetic circuit and one circular radially magnetized magnet inside this housing. Magnetic circuit has circular mounting surface. One side of this surface is provided with circular slot whose inner diameter is lesser than diameter of mounting surface. Each circular magnet is mounted on mounting surface by its inner surface. Circular magnets are made from material retaining its magnetic properties at temperature up to 120 C. Circular insert made from ferromagnetic material is located on outer surface of housing along radial axis. EFFECT: enhanced operational reliability.
