METHOD OF CRUDE OIL SLIME REFINING AND PURIFICATION OF EARTH SURFACE POLLUTED BY MAZUT Russian patent published in 2005 - IPC

FIELD: oil industry; improvement of ecology of a natural shelf.

SUBSTANCE: the invention is dealt with oil industry, in particular, with improvement of ecology of a natural shelf polluted by petroleum products located on the earth surface. The method provides for selection of a structure of the oil slime with a water share from 0.01 up to 99.9 %. In the oil slime they introduce components of a manure, using which every ten days and uniformly within one month they cover a volumetric mass of the oil slime by batches of 120, 150 and 500 %. In the produced volumetric composition of the processed mass of the oil slimes and the earth area polluted by mazut a stage by a stage and in proportion to the indicated ratio of the volumetric masses of the compost composition enter gypsum (CaSO₄) in the ratio from 10 up to 100 %, bring the treated mass of the oil slimes and-or the polluted by mazut earth area bring up to state of biochemical interacting of microorganisms. Under the action of the introduced components with microorganisms a porosity of the multicomponent treated material is formed. Then create conditions for infiltration into the formed porous compost composition of oxygen, use the conditions of a canalization of the process and heating of the compost mass from 10 up to 60 %, reduce the volume of evaporated water, proceed with the finishing multicomponent interconnection of the oil-oxidizing microorganisms with the changing in structure compost composition and transform the indicated structure of the oil slime and the ground polluted by mazut into a highly- humusized soil. The technical result is an increase of quality of preparation and production of a natural layer of the ground due to a change of elements of the components without additional steering of the compost composition.

EFFECT: the invention ensures increased quality of preparation and production of a natural layer of the ground without additional steering of the compost composition.
