Patent number: 7247279Abstract: System for removal of targeted pollutants from combustion and other industrial process gases and processes utilizing the system. Metal oxides are introduced from feeders into reaction zones of the system where they are contacted with a gas from which pollutants are to be removed. With respect to pollutant removal, the sorbent may interact with a pollutant as a catalyst, reactant, adsorbent or absorbent. Removal may occur in single-stage, dual-stage, or multi-stage systems with a variety of different configurations and reaction zones, e.g., bag house, cyclones, fluidized beds, and the like. Process parameters, particularly system differential pressure, are controlled by electronic controls to maintain minimal system differential pressure, and to monitor and adjust pollutant removal efficiencies. Reacted sorbent may be removed from the reaction action zones for recycling or recycled or regenerated with useful and marketable by-products being recovered during regeneration.Type: GrantFiled: June 9, 2003Date of Patent: July 24, 2007Assignee: EnviroScrub Technologies CorporationInventors: Kathleen S. Pahlman, legal representative, Steven C. Carlton, Ray V. Huff, Charles F. Hammel, Richard M. Boren, Kevin P. Kronbeck, Joshua E. Larson, Patrick A. Tuzinski, Steve G. Axen, John E. Pahlman, deceased

Patent number: 7232782Abstract: Methods and systems for regenerating and pretreating oxides of manganese and precipitation of oxides of manganese from manganese salt solutions. The oxides of manganese and manganese salt solutions are processed utilizing heated aqueous oxidizing solutions at or near boiling at atmospheric pressure. Solution temperature, Eh value and pH value are monitored and adjusted so as to move solution conditions into and to maintain them within the MnO2 stability area. This results in regenerated, pretreated and precipitated oxides of manganese having high or increased pollutant loading capacities and/or oxidation states. Oxides of manganese thus produced are, amongst other uses; suitable for use as a sorbent for capturing or removing target pollutants from industrial gas streams. Filtrate process streams containing useful and recoverable value present as spectator ions may be further processed to produce useful and marketable by-products.Type: GrantFiled: March 6, 2003Date of Patent: June 19, 2007Assignee: Enviroscrub Technologies Corp.Inventors: Charles F.

Patent number: 7041270Abstract: The invention relates to systems and processes for treating particulate oxides of manganese useful as oxidizing sorbents for capturing or removing target pollutants from industrial gas streams, including, but not limited to, nitrogen oxides (NOx), sulfur oxide (SOx), mercury (Hg), hydrogen sulfide (H2S), other totally reduced sulfides (TRS), and oxides of carbon (CO and CO2) gases. Oxides of manganese are washed an aqueous oxidizing solution, which may be adjusted as necessary to maintain the oxidizing solution a desired range of pH (acidity) and Eh (oxidizing potential) within the MnO2 stability area for aqueous solutions. The resulting treated oxides of manganese are equally or more efficient as sorbents as the oxides of manganese processed with the invention.Type: GrantFiled: December 23, 2002Date of Patent: May 9, 2006Assignee: Enviroscrub Technologies CorporationInventors: Charles F.

Patent number: 5196401Abstract: A method of enhancing the fragmentation and excavation of hard, solid materials such as rock formations is provided which comprises adding to the rock surface an aqueous solution including a high molecular weight nonionic polymer such as polyethylene oxide which is capable of hydrogen bonding with water to produce charge-neutralizing positive charge dipoles. The nonionic polymeric solution is thus capable of neutralizing the rock surface charge and obtaining a condition of zero surface charge (ZSC) so that the drilling, tunneling, cutting or other similar operation can be conducted with substantial increases in drilling performance and penetration rate. The method is also extremely effective in extending the lives of drill bits, cutting tools, grinding media, or other polishing or drilling tools such that an enormous savings in terms of replacing equipment can be achieved.Type: GrantFiled: July 18, 1990Date of Patent: March 23, 1993Assignee: The United State of America as represented by the Secretary of the InteriorInventors: William H.
