20090071334 | Convenient Substance-Recovery System and Process - A polar-substance-permselective membrane includes a porous support and an active-membrane material. The active-membrane material fills the pores of the porous support to render the support substantially impermeable to non-polar gases at a moderate pressure gradient (e.g., at least 70 kPa) when the hydrophilic active-membrane material is wet. In a particular embodiment the membrane is water-permselective and the active-membrane material is hydrophilic. Water-recovery system and processes utilizing these water-permselective membranes can be used to selectively remove water from hot gas streams at the feed side, and collect water at the permeate side with extremely high energy efficiency. The membrane is particularly useful for in-situ extraction of water molecules directly from hot exhaust streams. The produced steam, or steam and air mixtures can be used as a feedstock in the process of converting liquid hydrocarbons into hydrogen-rich gas streams. | 03-19-2009 |

A minimum quantity of stored hydrogen is maintained in the salt cavern to produce a stagnant layer having a carbon dioxide content along the cavern wall and the top of a residual brine layer located within the salt cavern. The compressed hydrogen feed stream is introduced into the salt cavern and the stored hydrogen stream is withdrawn without disturbing the stagnant layer to prevent carbon dioxide contamination from being drawn into the stored hydrogen stream being reintroduced into the hydrogen pipeline. This allows the stored hydrogen stream to be reintroduced into the hydrogen pipeline without carbon dioxide removal. | 05-05-2016 |
20160184765 | ADSORPTION AIR SEPARATOR WITH DRY AIR TAP - The adsorption based air separation unit includes an adsorber vessel containing media which selectively adsorbs water vapor and nitrogen preferentially over oxygen. The vessel includes an air entry spaced from an oxygen discharge. At least one dry air tap from the adsorber vessel is located between the entry and the discharge. When the adsorption media is fresh, air entering the adsorber vessel passes through enough of the adsorber vessel to have much of its water vapor removed and only some of its nitrogen removed. The vessel can include multiple taps sequentially further from the entry which can be selectively opened as the adsorption media becomes saturated with water vapor and nitrogen, so that dry air with much of its nitrogen still present can be further tapped from the adsorber vessel. The adsorber vessel thus facilitates production of both oxygen and dry air, such as for use as medical grade air. | 06-30-2016 |

20140150651 | SYSTEM AND PROCEDURE FOR EXTRACTING WATER FROM THE ENVIRONMENT - This invention provides a simple and energy-efficient process for obtaining water from air through better use of the solid desiccants using a high heating cycle in a confined space, applying minimal air flow and avoiding the use of a chilled condenser plate. The process of obtaining water in this invention consists of the production of water using, in one embodiment, a rotating drum covered with a desiccating material, a device that generates heat in a confined space, and a collection chamber. The process begins with charging the adsorbent material, which captures water vapor from the environment. Then, a discharging stage occurs through which an area of the desiccated material is exposed to controlled heating in a confined space, allowing the trapped water vapor to be released from the desiccant. A very light air flow may also be applied to increase the draw of the water vapor toward the area of condensation. A collection chamber is installed under the drum, allowing condensation of the water vapor released from the desiccating material. The recovered water accumulates and is stored in a storage tank. This invention does not need a chilled condenser plate to obtain the water vapor released by the desiccating material. As the process takes place, the drum rotates in such a fashion that the area with the charged desiccating material can be heated, allowing the area with the discharged desiccant to be charged again. | 06-05-2014 |
