Patent number: 8512445Abstract: The present invention relates to systems and processes for reducing the amount of carbon dioxide in a carbon dioxide-containing gas. In particular, the carbon dioxide-containing gas is contacted with a carbonate-containing solution. At least a portion of carbon dioxide in the carbon dioxide-containing gas is absorbed in the carbonate-containing solution to produce a carbon dioxide-, carbonate-containing solution. A heat recovery mechanism is employed to recover heat from the carbon dioxide-, bicarbonate-, carbonate-containing solution exiting the chamber to maintain the temperature of the chamber within a range of from about 50° C. to about 90° C.Type: GrantFiled: June 23, 2010Date of Patent: August 20, 2013Inventors: Shiaoguo Chen, Zijiang Pan

Patent number: 7223602Abstract: The invention provides a method of online and on-site tracer generation for tagging natural gas stored in underground storage fields wherein feedstock is drawn from a feedstock source. The feedstock undergoes initial analysis to determine hydrocarbon levels. The feedstock then undergoes reaction to produce tracers such as ethylene, propylene, acetylene hydrogen and carbon monoxide. The feedstock is then analyzed to determine post reaction tracer concentration. The feedstock including generated tracers is then introduced back into the feedstock stream. Tracer levels in the pre-reaction or initial analysis of feedstock are compared with tracer levels in the post-reaction feedstock and the rate of flow of feedstock through the system is adjusted to achieve a predetermined level of tracer concentration. The level of tracer concentration will then be used to identify the particular natural gas charge in a storage field.Type: GrantFiled: September 4, 2002Date of Patent: May 29, 2007Inventors: Dennis D. Coleman, Rodney R. Ruch, Shiaoguo Chen, Massoud Rostam-Abadi

Patent number: 6451094Abstract: A process for removing vapor phase contaminants from a gas stream includes the step of adding a raw carbonaceous starting material into a gas stream having an activation temperature sufficient to convert the raw carbonaceous starting material into an activated material in-situ. The activated material then adsorbs the vapor phase contaminants, and the activation material containing the vapor phase contaminants is removed from the gas stream using a particulate collection device. The process is particularly suited for the removal of vapor phase air toxics, such as mercury, from the flue gas of a combustion process. An apparatus for the removal of vapor phase contaminants from a gas stream is also described.Type: GrantFiled: February 26, 1999Date of Patent: September 17, 2002Assignee: The Board of Trustees of the University of IllinoisInventors: Ramsay Chang, Massoud Rostam-Abadi, Shiaoguo Chen
