  • Patent number: 5191767
    Abstract: The invention presented relates to a process and system for removing the moisture from the intake air of a gas turbine. More particularly, the process involves passing the intake air flow through a mesh pad to reduce the moisture level thereof downstream from the means used to cool the air prior to entering the gas turbine compressor.
    Type: Grant
    Filed: December 17, 1991
    Date of Patent: March 9, 1993
    Assignee: Mistop, Inc.
    Inventors: David M. Kane, William E. Fry
  • Patent number: 5074117
    Abstract: The invention provided relates to a process and system for treating the air in a building involving providing a series of air passages through the building; generating a flow of air through said series of air passages; cooling said air flow by means of at least one cooling coil; and reducing the moisture level of said cooled air flow by passing said cooled air flow through a mesh pad.
    Type: Grant

  • Patent number: 4575494
    Abstract: An alumina support which contains cesium is prepared by adding a fusible compound of cesium to alumina along with known binders and porosity control agents. The cesium compound should be fusible below the temperature at which the alumina fuses. Such a support is especially useful as a support for a silver catalyst employed in the oxidation of ethylene to ethylene oxide.

  • Patent number: 4428863
    Abstract: A process of making a high purity, low surface area porous alumina support having improved crush strength and abrasion resistance which comprises employing with the alumina a small amount of barium aluminate or silicate during its manufacture.
    Type: Grant

    Date of Patent: January 31, 1984
    Assignee: The Dow Chemical Company
    Inventor: William E. Fry
  • Patent number: 4248741
    Abstract: An improved process for preparing a silver catalyst which comprises impregnating a porous alumina support with a silver salt, preferably silver nitrate, by contacting a quantity of the support with an aqueous solution of the salt in sufficient amount to be completely absorbed by said support while under a vacuum. A dispersing agent is also employed in the aqueous silver salt solution. The support is dried by heating, e.g. 100.degree. C., under vacuum and then, while still under vacuum, impregnated with a reducing agent employing an amount sufficient to be completely absorbed by the support. Subsequent heating at a higher temperature, e.g. 250.degree. C., reduces the silver salt to silver metal. A catalyst is produced which, when employed for the oxidation of ethylene, permits the process to run 5.degree.-10.degree. C. cooler at the normal conversion and also gives an improved yield.
