Title:
METHOD FOR CLEANING CAPILLARY AND POROUS MEDIA CONTAMINATED BY CRUDE OIL AND PETROLEUM PRODUCTS
Document Type and Number:
WIPO Patent Application WO/1998/002259
Kind Code:
A1
Abstract:
The present invention relates to a method that comprises introducing into a zone to be cleaned a solution of micro-organisms capable of oxidising crude oil. Electrodes and more precisely an anode and a cathode are introduced into the cleaning zone, while an electrical direct current is generated between them in order to create an electro-osmotic movement of the solution containing the crude-oil oxidising micro-organisms. The solution which accumulates at the cathode is then collected and further re-introduced into the cleaning zone. According to the present invention, the crude-oil oxidising micro-organisms may be introduced to a desired depth, while the conditions of their vital functions may be improved relative to the oxygen content and to humidity. This invention may also be used to reduce the losses of solution containing the crude-oil oxidising micro-organisms by maintaining said solution within the cleaning zone.
