Publication number: 20230055251Abstract: A method and apparatus for recovering water from a heated gas mixture. The heated gas mixture is passed across one or more heat pipe heat exchangers connected in series. Each heat pipe heat exchanger includes an upper chamber separated from a lower chamber, and sealed heat pipes extending between the chambers. The heated gas mixture is passed across the lower chamber, where the heated gas mixture is cooled with the plurality of heat pipes, passing heat into the heat pipe fluid and thereby condensing water vapor to liquid water on an outside of the of heat pipes. Ambient air or other gas of a cooling temperature is passed across the upper chamber to reduce the heated temperature controlled fluid inside the plurality of heat pipes.Type: ApplicationFiled: August 18, 2022Publication date: February 23, 2023Applicant: UTILIZATION TECHNOLOGY DEVELOPMENT, NFPInventors: David M.

Patent number: 10173915Abstract: A method for removing gaseous inclusions from a viscous liquid in which a viscous liquid stream having gaseous inclusions is introduced into a refining chamber, resulting in a flowing viscous liquid layer. The viscosity of a bottom portion of the viscous liquid layer is reduced in a first refining zone in the refining chamber so as to produce an upwardly mobile reduced viscosity portion of the viscous liquid layer. Heat is introduced into the viscous liquid layer from above the viscous liquid layer in a second refining zone in the refining chamber downstream of the first refining zone, reducing the gaseous inclusions in said viscous liquid layer. Thereafter, the viscous liquid layer having substantially reduced gaseous inclusions is discharged from the refining chamber.Type: GrantFiled: February 18, 2011Date of Patent: January 8, 2019Assignee: GAS TECHNOLOGY INSTITUTEInventors: David M. Rue, V. Walter Kunc, John Charles Wagner, Chun W. Choi

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.
