Abstract
The present invention refers to a device with diametral magnetic arrays for installations in magnetic SUBs, aiming the remediation and mitigation of inorganic and organic scales in production columns. The proposed magnetic device meets several specific criteria based on the magnetohydrodynamic model (MHD). After applying the said device with the proposed magnetic field, an efficiency of the scale inhibition was experimentally observed through laboratory tests, obtained from the values of the masses encrusted in the walls of the experimental bench system in the laboratory, with respect to the application without magnetic field. The device described herein can be installed in any pipeline used to transport fluids, including underwater pipelines for oil wells. These fluids can be oils, lubricants, gases, steams, water, petroleum or liquids in general.
