Patent number: 7828880Abstract: A liquid film is formed on the surface of a porous body provided with a hydrophobic layer and hydrophilic layer, by moving thereon an ionic liquid having a selective absorption capacity of specific gas, and the specific gas within the gas to be processed is absorbed into the liquid film by bringing pressurized gas to be processed into contact with the liquid film. The specific gas is, for example, a carbon dioxide gas and the ionic liquid is, for example, an imidazolium salt. The specific gas absorbed into the liquid film is passed through the porous body by the use of a difference in pressure, whereby it is collected on a low pressure side. The specific gas absorbed into this collected liquid is then separated into a gas and a liquid by a separator, and the specific gas is released and collected.Type: GrantFiled: October 3, 2006Date of Patent: November 9, 2010Assignee: NGK Insulators, Ltd.Inventors: Yusuke Moriya, Toichiro Sasaki, Tetsuya Yanase

Publication number: 20090320689Abstract: A drift eliminator is formed from alternating curved spacers and corrugated spacer members to define tube-like passageways for the flow of air through an evaporative cooling apparatus. The formation of the corrugated blade member with beveled side walls places the back walls of the channels in a different plane than the front walls, with the lower edge of the front walls of the channels being positioned in a common plane along with the lower edge of the blade members. The angled side walls impede the formation of a film of water across the inlet opening into the channel, which requires an increase in horsepower for the fan to push air through the drift eliminator. Mechanical fastening devices molded into the respective members connects the corrugated spacer members and the blade members. A method of forming the corrugated spacer members to provide the angled side walls is also provided.Type: ApplicationFiled: June 26, 2008Publication date: December 31, 2009Inventors: Timothy E.

Patent number: 6582498Abstract: In a method of separating carbon dioxide from a gas mixture, a liquid solvent flows down an array of vertical wires with the gas mixture flowing over the liquid. Once on the wire, the liquid quickly breaks up into drops of varying sizes, with each size moving down the wire at a different velocity. Large, faster moving drops overtake the small, slower moving drops to form even larger drops. As the drops fall, new drops are created behind the falling drops. Consequently, drops of a large range of sizes are forming, colliding, and mixing as they travel down the wire. During this process, gas molecules that have adsorbed onto the liquid surface are mixed into the interior of the solvent, resulting in highly effective mass transfer and gas absorption. This enhanced mass transfer allows greater flexibility in the choice of solvent and in the system design.Type: GrantFiled: May 4, 2001Date of Patent: June 24, 2003Assignee: Battelle Memorial InstituteInventors: Bruce M. Sass, James H. Saunders, Bruce F. Monzyk, Russell H. Barnes, Jr., Neeraj Gupta, Paul R. Webb

Patent number: 6325361Abstract: In order to bring a gas and a liquid into contact with one another, for example so as to exchange, remove or add components or calorific value present in the gas and/or liquid, the liquid is guided along one or more walls which are provided with small openings, and the gas is guided into the liquid, via these openings, by allowing this liquid to flow along the walls or by moving the walls along the liquid. In order to increase the contact time between gas and liquid, the gas is guided into the liquid in a direction which essentially corresponds to the direction of movement of the liquid with respect to the wall which is provided with openings. A venturi effect is generated in the region of the openings, since subatmospheric pressure is produced at the location where the openings open into the stream of liquid.Type: GrantFiled: July 19, 1999Date of Patent: December 4, 2001Inventor: Albert Van Duijn
