Publication number: 20150204536Abstract: A method and system for steam generation and purification is presented. The method includes receiving a fuel stream, a water stream, and an oxidant stream in a direct contact steam generation (DCSG) apparatus; and generating a gas mixture stream comprising steam and carbon dioxide (CO2) in the DCSG apparatus. The method further includes receiving at least a portion of the gas mixture stream in a membrane separator, and separating at least a portion of the steam from the gas mixture stream to generate a permeate stream. The method further includes recirculating at least a portion of the permeate stream to the DCSG apparatus; monitoring a CO2 content in the gas mixture stream; and discharging at least a portion of the gas mixture stream at an outlet of the DCSG apparatus as a product stream if the CO2 content is lower than a determined value.Type: ApplicationFiled: January 17, 2014Publication date: July 23, 2015Applicant: General Electric CompanyInventors: Surinder Prabhjot Singh, Dhaval Ajit Bhandari

Patent number: 9074152Abstract: A plasma-assisted waste gasification system and process for converting waste stream reaction residues into a clean synthesis gas (syngas) is disclosed. The feedstock is fed into a reactor roughly one-third from the bottom through the use of a feed mechanism. The reactor has three zones; a bottom zone where melting occurs, a middle zone where gasification takes place, and a top zone with integrated plasma torches to control the temperature and polish the syngas. The residence times in the three zones are selected to optimize the syngas composition and melted products. The syngas leaves the reactor and is partially quenched with relatively cooler synthesis gas. The partially quenched syngas is further cooled to recover heat for steam generation and/or preheating the waste stream to the reactor. The cold syngas is then processed to remove pollutants. The clean synthesis gas is combusted in power generation equipment to generate electricity, or converted to other fuels by chemical processes.Type: GrantFiled: September 11, 2008Date of Patent: July 7, 2015Assignee: General Electric CompanyInventors: Matthew Christian Nielsen, Richard Anthony DePuy, Aditya Kumar, James Patrick Francis Lyons, Vitali Lissianski, Ruijie Shi, Surinder Prabhjot Singh, Kenneth Brakeley Welles, Vladimir Zamansky

Patent number: 9011647Abstract: A process for the plasma-assisted treatment of coal in which coal is directly converted to heavy hydrocarbons. The first step in the process is direct conversion of coal to aliphatic hydrocarbons under plasma conditions in the presence of light hydrocarbons, such as natural gas. In the second process step, the aliphatic hydrocarbons are upgraded to a liquid fuel. The energy for the process can be provided by radio frequency energy, such as microwave energy, that is powered by a renewable energy source. The process has flexibility to adjust aromatic content in the fuel to match fuel specification requirements.Type: GrantFiled: June 5, 2009Date of Patent: April 21, 2015Assignee: General Electric CompanyInventors: Vitali Victor Lissianski, Anthony Mark Thompson, Daniel Lawrence Derr, Gregg Anthony Deluga, Ramanathan Subramanian, Surinder Prabhjot Singh

Publication number: 20150004082Abstract: A system and method for treatment of a medium is disclosed. The system includes a plurality of separator zones and a plurality of heat transfer zones. Each of the separator zone and the heat transfer zone among the plurality of separator zones and heat transfer zones respectively, are disposed alternatively in a flow duct. Further, each separator zone includes an injector device for injecting a sorbent into the corresponding separator zone. Within the corresponding separator zone, the injected sorbent is reacted with a gaseous medium flowing in the flow duct, so as to generate a reacted gaseous medium and a reacted sorbent. Further, each heat transfer zone exchanges heat between the reacted gaseous medium fed from the corresponding separator zone and a heat transfer medium.Type: ApplicationFiled: June 28, 2013Publication date: January 1, 2015Inventors: Surinder Prabhjot Singh, Harish Radhakrishna Acharya, Robert James Perry, John Brian McDermott
