Latest Patents

Iversen holds a patent for a "Device and methods for discharging pretreated biomass from higher to lower pressure regions." This invention provides devices and methods for effectively discharging pretreated biomass from a pressurized reactor. The process involves adding pretreated, hot biomass under high pressure at the top of a discharge vessel, which is partially filled with water or an aqueous solution. The vessel is equipped with water jets that inject water or an aqueous solution to create strong turbulence in the lower part of the vessel. This turbulence, preferably a vortex turbulence or 'hydrocyclone,' blends the biomass and water, disintegrating any clumped material before ejecting it at high speed as a slurry through an orifice or valve at the bottom of the vessel. The design establishes a stable temperature stratification within the discharge vessel, allowing hot water to remain at the top and reducing heat and steam loss from the pretreatment reactor.
