  • Patent number: 9878191
    Abstract: Disclosed are a process and a system for treating contaminated soil. The process includes introducing a contaminated soil to an agitation unit. Ozone is supplied to the agitation unit thereby forming a soil-gas mixture, and the soil-gas mixture is agitated for sufficient time for the ozone to contact the contaminants thereby forming an ozone-treated soil and a residual gas-particulates mixture. The ozone-treated soil and the residual gas-particulates mixture are removed from the agitation unit. If necessary, remaining ozone is then flushed from the soil. The process occurs under negative pressure to prevent ozone from being released to the atmosphere.

    Abstract: In a method and apparatus for thermal processing of slurry, the slurry is combined with a bio-mass to produce a mixture which is then subjected to a cracking temperature in a receiving tank, thereby liquefying and allowing the mixture to catalytically undergo a cracking reaction. The cracking reaction which the liquefied mixture undergoes is continued in a mixer pump to thereby produce a reaction mixture. The reaction mixture is outgased in an intermediate tank to separate an outgased fraction from a non-outgased fraction. Subsequently, the outgased fraction is allowed to cool down, thereby producing fuel, while the non-outgased fraction is returned to the receiving tank and subjected again to the cracking temperature. Residual matter of the non-outgased fraction settles in the intermediate tank and is periodically removed.

  • Patent number: 8617480
    Abstract: A concentrated acid treatment unit is composed of a reaction section and an agitation extraction section. A phenol sorped raw material obtained by defatting botanical resource-derived raw material by solvent to subject sorption phenols to sorption is introduced, thus obtaining mixed solution of phenol solution including a lignophenol derivative and concentrated acid solution including a cellulose hydrolysate. The reaction section agitates and mixes the phenol sorped raw material and concentrated acid to cause cellulose to be swollen to thereby convert lignin to lignophenol. A part of the cellulose is subjected to hydrolysis. The agitation extraction section receives the treated liquid sent from the reaction section and adds phenols for extraction thereto to cause lignophenol dispersed in the concentrated acid solution to be dissolved and extracted in phenols for extraction.

  • Patent number: 8617899
    Abstract: A method and device for merging and mixing at least two separate and distinct fluid drops on a substrate, includes a drop merging area on the surface, where a first magnetic material is placed at a first location. A first drop of fluid is then placed at the first location on the surface, resulting in the first magnetic material being at least partially positioned within the first drop of fluid. A second drop of fluid is then placed at a second location on the surface of the drop merging area. A magnetic field is applied by a varying magnetic field generator to at least a portion of the drop merge area of the substrate, which includes at least the first location on the substrate. The varying magnetic field will act on the first magnetic material to move the first magnetic material within the first drop of fluid, causing a stirring of the fluid. A drop merging force from a drop merging mechanism is applied to at least one of the first drop of fluid and the second drop of fluid within the drop merge area.
