Abstract
An apparatus and process combines a mixture of hazardous waste generated by petroleum refining and/or production with a catalytic media and then process the mixture by subjecting the mixture to a heating process and a vacuum system to provide a dry solid fuel.
Claims13
A process for producing fuel from waste generated by petroleum refining and production, comprising the steps of:
- mixing oily waste emulsion with a catalytic media selected from at least one of kenaf, jute, coal, petroleum coke, tires, saw dust, tree bark, sewage sludge, and agricultural by-products;
- drying the mixture in a heated chamber to provide the fuel;
- simultaneously with heating, applying a vacuum to draw off distillation vapors, gases and water vapors;
- and
- separating the water and gases, recycling the water and the gases.

A process for producing fuel from oily waste water emulsions generated by petroleum refining and production, comprising the steps of:
- mixing oily waste water emulsion with a catalytic media selected from at least one of kenaf, jute, coal, petroleum coke, tires, saw dust, tree bark, sewage sludge, animal wastes, and agricultural byproducts;
- drying the mixture in an indirectly heated chamber to provide the high energy fuel;
- simultaneously with indirect heating, applying a vacuum to draw off distillation vapors, gases and water vapors;
- filtering the distillation vapors, gases and water vapors to remove dust and particulate matter;
- and
- separating the oil, water and gases, and recycling the oil, water and gases.
