Patent number: 8538717Abstract: A method and apparatus for absorbance correction in a spectroscopic heating value sensor in which a reference light intensity measurement is made on a non-absorbing reference fluid, a light intensity measurement is made on a sample fluid, and a measured light absorbance of the sample fluid is determined. A corrective light intensity measurement at a non-absorbing wavelength of the sample fluid is made on the sample fluid from which an absorbance correction factor is determined. The absorbance correction factor is then applied to the measured light absorbance of the sample fluid to arrive at a true or accurate absorbance for the sample fluid.Type: GrantFiled: January 28, 2011Date of Patent: September 17, 2013Assignees: Gas Technology Institute, North Carolina State UniversityInventors: Alexei Saveliev, Vilas Vyankatrao Jangale, Sergeui Zelepouga, John Pratapas

Patent number: 8139222Abstract: A method and system for measuring a physical property of a fluid in which light having wavelengths in the near-infrared is directed into a test cell containing the fluid and portions of the light not absorbed by the fluid and passing out of the cell are spatially dispersed by wavelength, forming a light spectrum that is projected onto a detector. The light spectrum is digitized and inputted into a data processing unit in which it is compared to the actual spectrum of the light source stored in the system to determine the absorbance spectrum of the fluid. The system is spectrally calibrated by identifying known spectral features of the fluid absorbance spectrum. To correct for deviations in the original light source spectrum, a calibration method in which the pressure of the fluid in the test cell is alternated between a first positive pressure and a second positive pressure is employed.Type: GrantFiled: March 1, 2010Date of Patent: March 20, 2012Assignee: Gas Technology InstituteInventors: Alexei Saveliev, Serguei Zelepouga, David M.

Patent number: 8110155Abstract: A vortex reactor is provided. The vortex reactor includes a reaction chamber formed by a frustum-shaped portion, the narrower part of which is downwardly oriented. Proximate to the narrower part of the frustum-shaped portion, the vortex reactor includes apparatus for creating an axial gas flow and apparatus for creating a circumferential gas flow. The vortex reactor also includes a particulate solid inlet for feeding particulate solids to the reaction chamber. The vortex reactor may optionally include apparatus for generating plasma in the reaction chamber by providing a gliding arc electrical discharge in the reaction chamber. Also provided is a method of processing particulate solids using the vortex reactor of the invention. A reverse vortex plasma reactor (TSAPG) is also provided.Type: GrantFiled: June 18, 2004Date of Patent: February 7, 2012Assignees: Drexel University, Board Of Trustees Of The University of IllinoisInventors: Alexander Fridman, Alexander F.
