Patents by Inventor Robert Geosits

Robert Geosits has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Direct sulfur recovery system
    Patent number: 7374742
    Abstract: The present invention provides a method for removing sulfur species from a gas stream without the use of a sulfur species removal process, such as an amine scrub. The sulfur species are removed by directly subjecting the gas stream to a sulfur recovery process, such as a Claus or sub-dewpoint Claus process at high pressure and moderate temperatures, wherein the sulfur recovery process comprises a catalyst which does not comprise activated carbon.
    Type: Grant
    Filed: December 19, 2003
    Date of Patent: May 20, 2008
    Assignee: Bechtel Group, Inc.

  • Efficient low temperature solvent removal of acid gases
    Patent number: 5289676
    Abstract: A high pressure synthetic gas stream is produced by gasifying coal. Hydrogen sulfide is removed by contacting the high pressure gas stream with a physical solvent, such as an alcohol, in an absorber column. A low temperature is maintained in the absorber column, typically by chilling both the solvent and the incoming high pressure synthetic gas stream, where a portion of the cooling requirement is supplied by adiabatically expanding the cleaned high pressure gas stream exiting the absorber. Typically, the cleaned high pressure gas stream will be expanded in a turbine expander to provide mechanical energy in addition to cooling capacity. The cleaned synthetic gas is useful as a fuel or chemical feedstock.
