Patent number: 7229066Abstract: An apparatus and method are provided for mixing a gas and a liquid to produce a gaseous vapor of the liquid that is substantially free of droplets. Gas, e.g., carbon dioxide, is divided into first and second streams. The first stream is combined in an atomization zone with the liquid, e.g., acetic acid, to form an atomized mixture of the gas and liquid. This atomized mixture is then contacted with the second gas stream in a mixing zone within a mixing/separation chamber in which the second gas stream vaporizes substantially all of the atomized liquid, and the resulting mixture of gas, vaporized liquid and residual droplets moves to the separation zone of the mixing/separation chamber. In the separation zone, the residual droplets gravitationally separate from the vaporized mixture, and the vaporized mixture free of a substantial amount of residual droplets is removed from the chamber.Type: GrantFiled: September 23, 2005Date of Patent: June 12, 2007Assignee: The BOC Group, Inc.Inventors: Michael D. Newman, Stephen A. McCormick, Helmut Dresselhaus

Patent number: 7147732Abstract: A hot object is quenched after heat treatment. A hot gas stream having at least 20% by volume of hydrogen is taken from for example a carburising chamber of a furnace. The gas is cooled by passage through a heat exchanger, and is compressed in a compressor. The compressor has an aftercooler (not shown) to remove heat of compression from the gas. The cooled, compressed gas flows through nozzles into a quenching chamber. The gas leaves the nozzles at a velocity of at least 50 m/s and impinges upon the hot metal object so as to effect its quenching.Type: GrantFiled: November 30, 2001Date of Patent: December 12, 2006Assignee: The BOC Group plcInventor: Paul Stratton
