  • Publication number: 20240124781
    Abstract: A distillation system including a retort and a distillation column. The retort includes an inlet end, an outlet end opposite the inlet end and including an outlet opening, a rotatable drum configured to heat a product therein and move the product between the inlet end and the outlet end. The distillation column is coupled to the outlet end of the retort and configured to receive the product therein upon exiting the outlet opening of the retort. The distillation column includes a solid particle trap section positioned above the outlet opening, a packing section positioned above the solid particle trap section and including screen at a bottom end thereof, a dust filter therein, and a first bubble tray section positioned above the packing section and including a first outlet feed for outflow of a first fluid product.

  • Patent number: 11168258
    Abstract: A retort including a drum, an electric induction coil, a motor, and first and second jacks. The drum includes an inlet port at an inlet end, an outlet port at an outlet end, and a cylindrical tube extending between the inlet end and the outlet end. The electric induction coil is proximate the cylindrical tube for heating the cylindrical tube. The motor is operably and rotatably coupled to the cylindrical tube of the drum. The first jack is coupled to the drum proximate the inlet end, and is configured to raise and lower the inlet end of the drum. And the second jack is coupled to the drum proximate the outlet end, and is configured to raise and lower the outlet end of the drum.

  • Patent number: 8328992
    Abstract: A retort involves a stack of retort units arranged to process coal or other raw material by heating the coal in a heating compartment and directing vapors emitted from the raw material into a vapor compartment surrounding the heating compartment. The heating compartment may include a plurality of louver units with embedded heating components. Each louver unit includes heating fins (a heat transfer medium) that delivers heat to the coal. Each louver unit also includes an insulation layer adjacent a vapor opening where vapors emitted from the coal pass into the vapor compartment. The vapors are directed to a distillation column where carbon based vapors, volatiles, fuel vapors and the like may be liquefied for transport to a refinery or directly refined into fuels. Further, a clean coal char (toxins and carbon vaporized) is delivered to a power generation plant to provide cleaner emissions relative to unprocessed coal.
