Patent number: 9150799Abstract: A system and method for processing solid waste products includes an autoclave, a combined heat and power generation system and a water treatment system. Water in the solid waste products is vaporized to raise steam, by heating the autoclave. Waste liquids, steam and cellulosic material are removed from the autoclave. The cellulosic material is combusted in the heat and power generation system, which generates steam and electricity, with the steam recycled to the autoclave. The steam and the waste liquids are processed in the water treatment system, with the cleaned water cycled to the heat and power generation system to be converted into steam.Type: GrantFiled: December 21, 2009Date of Patent: October 6, 2015Assignee: Estech USA, LLCInventors: Jan K.

Publication number: 20100135851Abstract: An autoclave system provides a means of sterilizing municipal solid waste, hydrolyzing many of its components, and preparing the material for post-autoclave automated separations. The present apparatus provides a means of drying the solid waste in the vessel, while conserving the energy used to dry the vessel. Non-contact steam is recovered through separations of steam and water, with condensate steam pressure regenerated by mechanical vapor recompression and condensate water returned to the boiler/steam generator. Heat transfer to combustion air, by heat transfer via heat pump to generate additional steam, and/or by mechanical vapor recompression recovers the latent heat of loose contact steam condensate. The process design provides for in-vessel drying while reducing the energy cost of operating a waste autoclave, as compared to the current art.Type: ApplicationFiled: December 1, 2008Publication date: June 3, 2010Inventors: Jan K.
