Patent number: 9080768Abstract: Gasifier preheater fuel and moderator injection apparatus, systems and methods are provided. A preheater distributor ring is securely mounted within the shell dome of a gasification vessel, for the selective discharge of preheat fuel and oxidizer into the vessel during preheating operations, or for the selective discharge of moderating agents into the vessel during normal gasification operations.Type: GrantFiled: November 8, 2012Date of Patent: July 14, 2015Assignee: General Electric CompanyInventors: John Caleb Wilson, Jennifer Lucia Ramirez, James Scott Kain, Shaoping Shi, Dinh-Cuong Vuong, Edward Pan

Publication number: 20150014142Abstract: A method for processing wastewater is provided. The method includes pretreating a flow of the wastewater using at least one of a softening/clarification system, a sludge handling system, a filtration system, and an ammonia stripping system, evaporating the pretreated flow to produce at least a distillate and an evaporator brine; separating the evaporator brine to produce a liquid recycle stream and salt crystal mixture; and channeling the liquid recycle stream to a feed stream. The method eliminates the salt drying process that significantly reduces the costs of construction and operation of the standard zero process water discharge process.Type: ApplicationFiled: September 19, 2014Publication date: January 15, 2015Inventors: Dinh-Cuong Vuong, James Scott Kain

Patent number: 8728328Abstract: A method of removing suspended solids from a gasification process water stream includes, in an exemplary embodiment, providing a gasification process water stream containing process derived suspended solids, settling at least a portion of the suspended solids from the process water stream in a settling apparatus, providing a filter apparatus having a plurality of filter elements, and removing a portion of the settled solids from the settling apparatus. The method also includes precoating the filter elements with the settled solids removed from the settling apparatus, directing a portion of the process water stream from the settling apparatus to the filter apparatus, and filtering the portion of the process water stream directed from the settling apparatus through the precoated filter elements to remove suspended solids particles to form a filtrate.Type: GrantFiled: October 23, 2007Date of Patent: May 20, 2014Assignee: General Electric CompanyInventors: James Scott Kain, Priyadharshini Swaminathan, Dinh-Cuong Vuong

Publication number: 20130270181Abstract: Selenium in the form of a reduced species such as selenocyanate is oxidized to produce an oxidized selenium species such as selenate or selenite, and then a biological reduction process is used to remove selenium from the oxidized selenium species. In an example, a chemical oxidant is added to a wastewater containing selenocyanate to produce selenate and selenite. The partially treated wastewater is then fed to a reactor containing a fixed media supporting a biofilm with selenium reducing organisms. The selenium in the selenate and selenite is reduced to an insoluble form of selenium, such as elemental selenium, which precipitates from the wastewater.Type: ApplicationFiled: March 15, 2013Publication date: October 17, 2013Inventors: Timothy Michael PICKETT, Yanguo MA, Jill SONSTEGARD, James Scott KAIN, Dinh-Cuong VUONG, David Brian FRASER
