Patent number: 8999278Abstract: The invention provides various methods for removing gas phase pollutants by calcining limestone or dolomite using flash calcination to produce a high surface area lime or hydrated lime and directly adding the lime or hydrated lime to a gas stream containing gas phase pollutants. In other methods, the production of an activated sorbent, such as activated carbon, is combined with the production of the high surface area lime or hydrated lime and directly added to a gas stream containing gas phase pollutants. The combination of lime or hydrated lime and an activated sorbent enhances the removal of gas phase pollutants such as those from a coal-fired boiler flue gas.Type: GrantFiled: March 11, 2010Date of Patent: April 7, 2015Assignee: The Board of Trustees of the University of IllinoisInventors: Ramsay Chang, Yongqi Lu, Massoud Rostam-Abadi

Patent number: 8062408Abstract: Methods and systems for separating a targeted gas from a gas stream emitted from a power plant. The gas stream is brought into contact with an absorption solution to preferentially absorb the targeted gas to be separated from the gas stream so that an absorbed gas is present within the absorption solution. This provides a gas-rich solution, which is introduced into a stripper. Low pressure exhaust steam from a low pressure steam turbine of the power plant is injected into the stripper with the gas-rich solution. The absorbed gas from the gas-rich solution is stripped in the stripper using the injected low pressure steam to provide a gas stream containing the targeted gas. The stripper is at or near vacuum. Water vapor in a gas stream from the stripper is condensed in a condenser operating at a pressure lower than the stripper to concentrate the targeted gas. Condensed water is separated from the concentrated targeted gas.Type: GrantFiled: May 8, 2007Date of Patent: November 22, 2011Assignee: The Board of Trustees of the University of IllinoisInventors: Shiaguo Chen, Yonggi Lu, Massoud Rostam-Abadi

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: 6558454Abstract: 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 raw carbonaceous starting material can be either a solid-phase, liquid phase or vapor-phase material. 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 27, 2001Date of Patent: May 6, 2003Assignee: Electric Power Research Institute, Inc.Inventors: Ramsay Chang, Massoud Rostam-Abadi, Sharon Sjostrom

Patent number: 5854173Abstract: A method for removing vapor phase contaminants from a gas stream. Sorbent particles are injected into the gas stream to react with vapor phase contaminants in the gas stream. Each sorbent particle is made from a support particle of a material coated with a layer of sorbent material different than the material of the support particle. The gas stream is directed through a particulate control device to remove the sorbent particles from the gas stream. A sorbent particle for use in the method and a method for manufacture of the sorbent particle are provided.Type: GrantFiled: May 31, 1996Date of Patent: December 29, 1998Assignee: Electric Power Research Institute, Inc.Inventors: Ramsay Chang, Massoud Rostam-Abadi
