Patent number: 10619890Abstract: A thermal receiver, such as a solar flux thermal receiver, is disclosed comprising a modular arrangement of arrayed microchannels or micropins to heat a working fluid by heat transfer. Disclosed solar receivers provide a much higher solar flux and consequently a significant reduction in thermal losses, size, and cost, relative to known receivers. Unit cell receivers can be numbered up and combined in parallel to form modules, and modules combined to form full scale receivers.Type: GrantFiled: July 5, 2017Date of Patent: April 14, 2020Assignees: Oregon State University, The Regents of the University of CaliforniaInventors: Monte Kevin Drost, Sourabh Apte, Thomas L'Estrange, Vinod Narayanan, Charles Rymal, Eric Truong, Erfan Rasouli, Kyle Ryan Zada, Brian M.

Patent number: 6974496Abstract: The present invention provides compact adsorption systems that are capable of rapid temperature swings and rapid cycling. Novel methods of thermal swing adsorption and thermally-enhanced pressure swing adsorption are also described. In some aspects of the invention, a gas is passed through the adsorbent thus allowing heat exchangers to be very close to all portions of the adsorbent and utilize less space. In another aspect, the adsorption media is selectively heated, thus reducing energy costs. Methods and systems for gas adsorption/desorption having improved energy efficiency with capability of short cycle times are also described. Advantages of the invention include the ability to use (typically) 30-100 times less adsorbent compared to conventional systems.Type: GrantFiled: June 30, 2003Date of Patent: December 13, 2005Assignee: Battelle Memorial InstituteInventors: Robert S.

Publication number: 20050126211Abstract: Microchannel or fractal plate desorption retains the advantage of high-flux, thin-film desorption without using membranes and allows for lightweight, compact desorbers for either LiBr and water or ammonia and water. Working embodiments of the process comprise providing a droplet desorber, feeding a multicomponent fluid mixture comprising at least a first fluid and a second fluid to the desorber, and performing a desorption process on the mixture using the desorber. The primary fluid mixtures used were ammonia and water, and aqueous lithium bromide. Various working embodiments of desorbers are disclosed, including several desorbers comprising plural, substantially straight, substantially parallel microchannels in an array, and a fractal plate desorber, such as a bifurcating fractal plate.Type: ApplicationFiled: December 15, 2004Publication date: June 16, 2005Inventors: Kevin Drost, Vinod Narayanan, Deborah Pence
