Publication number: 20110232485Abstract: A composite desiccant material is formed by a porous, absorbent substrate of PVA foam or non-woven fibrous sheet is soaked in a solution of a hygroscopic desiccant such as CaCl. The desiccant is held in pores or fibrous entraining areas sized ranging from 50 microns to 1000 microns. Thin sheets are arranged in a stack in a multi-chamber system, while in an absorption state, uses this stack in a main chamber to absorb H2O from atmospheric gas flowing through that chamber. In a regeneration state atmospheric flow is stopped and low-grade energy releases the H2O from the desiccant into that chamber. Fans circulate moist air through the main chamber and into an adjacent chamber for H2O transfer through or past a partially permeable barrier into a cooling/condensing area. Both H2O and dry gas may be produced.Type: ApplicationFiled: March 28, 2011Publication date: September 29, 2011Inventor: Joseph Ellsworth

Patent number: 8025720Abstract: Systems and methods for processing methane and other gases are disclosed. A representative method in accordance with one embodiment includes directing a first portion of a gas stream through a first adsorbent while exchanging heat between a second adsorbent and a third adsorbent. The method can further include directing a second portion of the gas stream through the third adsorbent while exchanging heat between the first and second adsorbents. The method can still further include directing a third portion of the gas stream through the second adsorbent while exchanging heat between the first and third adsorbents. In further particular aspects, the adsorbent can be used to remove carbon dioxide from a flow of methane. In other particular aspects, a heat exchange fluid that is not in direct contact with the adsorbents is used to transfer heat among the adsorbents.Type: GrantFiled: May 17, 2010Date of Patent: September 27, 2011Assignee: Prometheus Technologies, LLCInventors: John A.

Publication number: 20110168025Abstract: A fuel vapour storage canister, e.g. a carbon canister for use in an automobiles evaporative fuel vapour emissions control system is described. The canister comprises a housing defining an inner wall and an outer wall; a first fuel vapour storage compartment arranged within a volume defined by the inner wall; and a second fuel vapour storage compartment in fluid communication with the first vapour storage compartment via an air-flow channel, wherein the air-flow channel includes a section arranged to pass between the inner and outer walls of the housing and to provide a heat-exchange function. Thus air cooled by endothermic desorption in the second fuel vapour compartment during canister purging may be warmed by the ambient air (or other thermal-mass) surrounding the outer wall before it reaches the first fuel vapour compartment, thus providing for more efficient desorption in the first fuel vapour compartment.Type: ApplicationFiled: September 21, 2009Publication date: July 14, 2011Applicant: MAST CARBON AUTOMOTIVE LTD.Inventor: Tho Troung Huynh
