Abstract

Apparatus for removing clay, soil, silt and other excess or non-suitable contaminants adhering to particulate materials, comprises an elongate conduit (1 ) whose longitudinal axis is set an angle to the horizontal whereby particulate material can pass through the conduit under the influence of gravity. The wall of the conduit has a plurality of fine apertures (2) therethrough extending along the conduit and arranged around the conduit. A pressure chamber (5) surrounds the conduit (1), the apertures (2) communicating with the chamber. Water is supplied under pressure to the chamber to create fine high pressure jets which dislodge any contaminants from the particles.

Claims

6AMENDED CLAIMS received by the International Bureau on 01 June 2009 (01.06.2009)
1. Apparatus for removing contaminants adhering to particulate materials, comprising an elongate conduit whose longitudinal axis is set an angle to the horizontal whereby particulate material can pass through the conduit un- der the influence of gravity, the wall of the conduit having a plurality of fine apertures therethrough extending along the conduit and arranged around the conduit, a pressure chamber surrounding the conduit, the apertures communicating with the chamber, and means for supplying water under pressure to the chamber.
2. Apparatus according to Claim 1 , wherein the conduit is a tube.
3. Apparatus according to Claim 1 or 2, wherein the apertures are arranged in a spiral path along the length of the conduit.
4. Apparatus according to Claim 3, wherein the apertures are arranged in a double spiral path along the length of the conduit.
5. Apparatus according to any preceding claim, wherein the apertures have a diameter of less than 0.5mm.
6. Apparatus according to Claim 5, wherein the apertures have a diameter of 0.3mm.
7. Apparatus according to any preceding claim, wherein the water supply is such that the pressure in the pressure chamber is 20MPa (200 bar).
8. A method of removing contaminants adhering to particulate materials, comprising passing the materials through an elongate conduit surrounded by a pressure chamber, supplying the pressure chamber with water under pressure, thereby supplying multiple fine high pressure water jets directed into the material from a plurality of directions along the length of the conduit, and then separating the water from the materials passing out of the conduit.
9. A method according to Claim 8, comprising generating the jets by providing apertures through the wall of the conduit, the apertures having diameters less than 0.5mm.
10. A method according to Claim 9, comprising applying the water at a pressure of 20MPa in the pressure chamber.
11. A method according to any of Claims 8, 9 and 10 for recovery of oil from oil-contaminated sand or sediment, comprising the further step of extracting the oil from the aqueous emulsion passing out of the conduit.
