Publication number: 20100243245Abstract: A process and system for release and recovery of methane from subterranean methane hydrate deposits in which heated CO2 is used to displace methane from the methane hydrate deposits and a portion of the displaced methane is routed to a combustion device proximate the deposit for combustion in-situ, generating heated CO2 which is introduced into the deposit, displacing additional methane, a portion of which is routed to the combustion device, thereby providing a substantially self-sustaining process. Portions of the displace methane not routed to the combustion device are captured for use elsewhere.Type: ApplicationFiled: March 30, 2009Publication date: September 30, 2010Applicant: GAS TECHNOLOGY INSTITUTEInventors: Mark J.

Patent number: 7780436Abstract: A combustion method and apparatus which produce a hybrid flame for heating metals and metal alloys, which hybrid flame has the characteristic of having an oxidant-lean portion proximate the metal or metal alloy and having an oxidant-rich portion disposed above the oxidant lean portion. This hybrid flame is produced by introducing fuel and primary combustion oxidant into the furnace chamber containing the metal or metal alloy in a substoichiometric ratio to produce a fuel-rich flame and by introducing a secondary combustion oxidant into the furnace chamber above the fuel-rich flame in a manner whereby mixing of the secondary combustion oxidant with the fuel-rich flame is delayed for a portion of the length of the flame.Type: GrantFiled: June 1, 2005Date of Patent: August 24, 2010Assignee: Gas Technology InstituteInventors: Vasilios Soupos, Serguei Zelepouga, David M.

Publication number: 20030123518Abstract: A method for high temperature process control in which the surface emission intensity of a surface is measured at two near-infrared wavelengths over an array of points covering a fill field of view. The emissivity variable is removed from the temperature calculation and the surface emission intensity measurements are digitally processed, resulting in generation of a color temperature map. The color temperature map is processed in a thermal imaging control algorithm process, producing control output signals, which are then input to a temperature control means for controlling the surface temperature. The apparatus used in carrying out this method is surface temperature monitoring system which includes a multiple-wavelength, near-infrared thermal imaging system.Type: ApplicationFiled: January 3, 2002Publication date: July 3, 2003Inventors: Hamid A.
