METHOD OF SEPARATION OF SOLID AND LIQUID PHASES OF SATURATED TECHNOGENIC OIL SEDIMENTATION Russian patent published in 2010 - IPC C02F11/14 C02F1/461 

FIELD: process engineering.

SUBSTANCE: invention can be used for dehydration of various technogenic oil sedimentation and to separate oil products from various oil-containing technogenic sedimentation. Proposed method comprises preliminary determination of initial pH of oil sedimentation. If it makes 7≤pH≤10, the latter is treated by water steam heated to 60-200°C and activated by passing through electrolyser anode zone to produce 2≤pH≤5 in amount sufficient for reduction in pH by 1-3 units. If initial pH makes, 4≤pH≤7, oil sedimentation latter is treated by water steam heated to 60-200°C and activated by passing through electrolyser anode zone to produce 9≤pH≤12 in amount sufficient for reduction in pH by 1-3 units.

EFFECT: efficient separation into solid, liquid and gaseous phases.
