METHOD FOR OIL AND OIL PRODUCTS REMOVING FROM WETLAND Russian patent published in 2017 - IPC E02B15/04 B09C1/00 

FIELD: oil and gas industry.

SUBSTANCE: in the direction of oil and oil products collection device movement, a wetland polluted by oil and oil products is limited in the length and width to form a limited area. Water is supplied across the wetland limited area to the predetermined depth. Across the limited area, the oil-water mixture is deformed with peat and bog vegetation. The resulting oil-water mixture is drained over the entire wetland limited area from peat and bog vegetation during heating across the wetland closed area. Oil-water mixture is accumulated in the oil and oil products collection device. The mixture is separated into oil and water in the oil and oil products collection device by settling and during heating. The separated oil or oil products are pumped under laminar-flow mode through the pipeline into the oil collector. A biodegradable sorbent is applied over the entire wetland area purified from oil.

EFFECT: increased efficiency in cleaning wetlands polluted by oil and oil products, lower energy costs, reduced harmful impact on the natural wetland structure.
