1. WO1997014528 - PLASMALYSIS TREATMENT METHOD FOR WASTE MATTER

Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

What is claimed is:

1. A method of treating particulate waste matter by electrical discharge comprising the steps of:
positioning a plurality of electrode structures to define a plasmalysis zone;
establishing an atmosphere free of ambient reactants within said plasmalysis zone;
introducing the particulate matter to be treated into the plasmalysis zone; and
producing a plurality of discrete electrical discharges in a desired sequence between said electrode structures.

2. The method of claim 1, wherein the particulate waste matter is impregnated with waste oil.

3. The method of claim 1, wherein the particulate waste matter incorporates waste oil.

4. A method of treating particulate waste matter by electrical discharge within a conditioned treatment zone which comprises:
establishing an atmosphere free of ambient reactants within the treatment zone;
passing particulate waste matter to be treated through the treatment zone; and subjecting the whole of the treatment zone to a sequence of discrete electrical discharges in a time interval less than the transit time of particulate matter through the treatment zone whereby the particulate matter within the treatment zone is plasmalyzed.

5. The method of claim 4, wherein the particulate matter is impregnated with waste oil.

6. The method of claim 4, wherein the particulate waste matter incorporates waste oil.

7. A method of plasmalyzing particulate matter by electrical discharge comprising the steps of:
positioning a plurality of electrode structures to define a desired plasmalysis zone;
conditioning the plasmalysis zone, including establishing an atmosphere free of ambient reactants within the plasmalysis zone;
passing particulate matter to be treated through the plasmalysis zone; and
subjecting substantially the entire plasmalysis zone to discrete electrical discharges within a time interval considerably less than the expected residence time of a particle to be plasmalyzed within the plasmalysis zone.

8. The method of claim 7, wherein the particulate matter is particulate waste material.

9. The method of claim 7, wherein the particulate waste matter incorporates waste oil.

10. The method of claims 1, 4 or 7 further comprising the steps of:
subjecting the treated particulate matter to oxidizing conditions.

11. The method of claim 10, wherein the particulate waste matter is impregnated with waste oil.

12. The method of claim 10, wherein the particulate waste matter incorporates waste oil.
