PROCEDURE FOR PURIFICATION OF OIL AND OIL PRODUCTS FROM SULPHUR COMPOUNDS Russian patent published in 2010 - IPC C10G29/04 C10G32/02 

FIELD: gas-and-oil industry.

SUBSTANCE: invention refers to processes of oil and oil products purification from sulphur compounds and can be implemented in cycle of preparing crude to processing or refining oil products before usage. The invention refers to the procedure of oil or oil products from sulphur compounds by means of contacting with settled copper on iron charge, separation of charge and successive dissolution of extracted sulphur compounds in solvent, and regeneration of activity of charge copper component and solvent. Also purification is performed in a counter-flow of oil or oil products flow supplied from "below-upward" and flow of iron charge with settled copper supplied from "top-downward". Created dynamic heterogeneous system "liquid-solid" is treated with ultrasound of 10-25 kHz frequency and power 1-3 kWt. Notably, weight amount of copper in charge to weight amount of common sulphur in oil or oil products is varied within ranges: Cu _{in charge}: S_Common: (1.5-2.0);1.0.

EFFECT: processing oil with high contents of sulphur (S over 5%) to contents of sulphur in refined product - 0,005%.
