Abstract
This disclosure relates to a processor comprising means for mixing a process material with a process liquid (such as water) and forming an emulsion or slurry. Means is provided for pressuring and heating the slurry, and the slurry is then fed to means for quickly reducing the pressure to a relatively low value and further increasing the temperature. The rapid drop in pressure and increase in temperature causes volatile components of the slurry to convert to a gas and separate from the remainder of the slurry which is removed from the processor in the form of solids. The gas is fed to one or more condensers which separate the gas into useful liquids such as various grades of oil.References Cited

Independent Claims | See all claims (12)
- 1. A process for converting a process material into other useful products, comprising the steps of:mixing the process material with a process liquid to create a flowable emulsion,pumping said emulsion to an expansion container while preheating said emulsion with a least one heated fluid from the process,further quickly reducing the pressure on said emulsion while quickly heating said emulsion with a heating source to separate volatile in said emulsion,collecting said separated volatile, andcollecting said separated solids.
- 3. A thermal depolymerization processor for converting a process material into other use products comprising:a) a mixer means for mixing the process material with a process liquid and for forming a flowable slurry;b) a first system means connected to said mixer means for receiving, heating and increasing the pressure applied to said slurry;c) a second system means connected to said first system means for receiving and quickly reducing said pressure applied to said slurry and for quickly heating and reforming said slurry into a first by-product and a second by-product;d) a first collection means for receiving said first by-product from said second system means; and,e) a second collection means for receiving said second by-product from said second system means.
- 7. A thermal depolymerization processor for converting a process material into other useful products comprising:a) a mixer adapted for mixing the process material with a process liquid and for forming a flowable slurry;b) a conduit connected at one end to said mixer having at a first end a pump and at a second end a valve therein adapted for receiving, heating and increasing the pressure applied to said slurry;c) an expansion container connected to said second end of said conduit adapted for receiving and quickly reducing said pressure applied to said slurry having heating means for quickly heating and reforming said slurry into a first by-product and a second by-product;d) a first collection means for receiving said first by-product from said expansion container; and,e) a second collection means for receiving said second by-product from said expansion container.
- 11. A thermal depolymerization processor for converting a process material into other useful products comprising:a) a grinder adapted for grinding the process material;b) a mixer adapted for receiving and mixing the process material with a process liquid to form a flowable slurry;c) a first conduit connected at one end to said mixer having at a first end a pump and at a second end a valve therein adapted for receiving, heating and increasing the pressure applied to said slurry;d) an expansion container connected to said second end of said first conduit adapted for receiving and quickly reducing said pressure applied to said slurry and for quickly heating and reforming said slurry into a solid by-product and a first gas by-product;e) a primary condenser connected to said expansion container adapted for receiving, cooling and increasing said pressure applied to said first gas by-product and for separating said first gas by-product into both a second gas by-product and a liquid by-product;f) a second conduit adapted for connecting said expansion container to said primary condenser and transporting said first gas by-product to said primary condenser;g) a secondary condenser connected to said primary condenser adapted for receiving and increasing said pressure applied to said second gas by-product and for cooling and separating said second gas by-product into a third gas by-product and a fourth gas by-product;h) a first collection means for receiving and collecting said solid by-product from said expansion container;i) a second collection means for receiving and collecting said liquid by-product from said primary condenser;j) a third collection means for receiving and collecting said third gas by-product from said secondary condenser; andk) a fourth collection means for receiving and collecting said fourth gas from said secondary condenser.
