Patent number: 7449054Abstract: The invention teaches a purification system which uses a series of operations, in a single unit, to purify air, while extending the life of the purification units. Air is passed through a coarse water trap to remove liquid. The semi-dry air, is then passed through adsorbers, which remove the remaining moisture and all the carbon dioxide in a purification process. The present invention flows the air to be purified through adsorption columns twice, before and after passing the air through an oxygen catalyst unit. The flows of air are then rotated to a third column, which is thermally regenerating with the facilitation of a regeneration air supply from the purified air.Type: GrantFiled: August 25, 2005Date of Patent: November 11, 2008Assignee: SAES Pure Gas, Inc.Inventors: Lawrence A. Rabellino, Charles H. Applegarth, Matthew D. Schlotterbeck, Giorgio Vergani

Publication number: 20030143129Abstract: The invention teaches a purification system which uses a series of operations, in a single unit, to purify air, while extending the life of the purification units. Air is passed through a coarse water trap to remove liquid. The semi-dry air, which is usually less than 3000 ppm of water vapor, is then passed through adsorbers, which remove the remaining moisture and all the carbon dioxide in a purification process. The drying of the air before passing it through the adsorbers allows for greatly improved efficiency of air purification and extends the life of both the oxygen catalyst and the adsorption columns. The present invention also flows the air to be purified through adsorption columns twice, before and after passing the air through an oxygen catalyst unit.Type: ApplicationFiled: October 31, 2002Publication date: July 31, 2003Inventors: Lawrence A. Rabellino, Charles H. Applegarth, Matthew D. Schlotterbeck, Giorgio Vergani

Patent number: 6398846Abstract: A semiconductor manufacturing system includes a getter-based gas purifier coupled in flow communication with a gas distribution network for a semiconductor fabrication facility. The gas distribution network supplies purified gas to at least one wafer processing chamber in the semiconductor fabrication facility. The gas purifier includes a getter column having a metallic vessel with an inlet, an outlet, and a containment wall extending between the inlet and the outlet. Getter material which purifies gas flowing therethrough by sorbing impurities therefrom is disposed in the vessel. A first temperature sensor is disposed in a top portion of the getter material. The first temperature sensor is located in a melt zone to detect rapidly the onset of an exothermic reaction which indicates the presence of excess impurities in the incoming gas to be purified. A second temperature sensor is disposed in a bottom portion of the getter material.Type: GrantFiled: November 7, 2000Date of Patent: June 4, 2002Assignee: Saes Pure Gas, Inc.Inventors: D'Arcy H. Lorimer, Charles H. Applegarth

Patent number: 6299670Abstract: The present invention provides a method and apparatus to purify various gases utilizing the superior performance a heated getter process in a smaller package than previous multiple stage, heated getter processes. The smaller package includes inner and outer enclosures, and an integral, regenerative heat exchanger to simultaneously increase heater efficiency and cool the purified gas. The invention also includes a particle filter to remove particles from the gas flow. The invention further provides an interface to various modular gas stick substrate designs with an inlet and an outlet in one end of the integrated heated getter purifier system. The inlet gas is preheated by the integral heat exchanger and then heated to operating temperature of 200-400° C. The heated getter removes various impurities from the gas. The heated gas is then cooled in the integral heat exchanger. The cooled gas is exposed to a second quantity of cooler getter to remove residual impurities.Type: GrantFiled: June 10, 1999Date of Patent: October 9, 2001Assignee: SAES Pure Gas, Inc.Inventor: Charles H.
