FIELD: petroleum chemistry. SUBSTANCE: sample of oil is heated to point of melting of organic deposits and then it is magnetized in permanent magnetic field at constant rate. Then, sample is kept beyond magnetic field for at least an hour at melting point of organic deposits after which metallic specimen is immersed in sample where it is kept for a definite period of time. Efficiency of magnetic treatment is shown by difference of magnetic depositions from magnetized and non-magnetized samples of oil metallic specimen. EFFECT: enhanced reliability of method. 3 cl, 1 dwg
