Scott D. KELMAN 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).

  • Heating component to reduce solidification in a cryogenic distillation system
    Patent number: 10365037
    Abstract: A method and a system for feeding a feed gas including methane (CH4) and carbon dioxide (CO2) to a cryogenic distillation column are provided herein. The method includes flowing a freeze zone CO2 vapor stream into a freezing section of the column to produce an overhead stream that exits the column. The method includes heating the overhead stream via a heating component to reduce or prevent solidification of the CO2 in the overhead stream.
    Type: Grant
    Filed: June 30, 2016
    Date of Patent: July 30, 2019
    Assignee: ExxonMobil Upstream Research Company
    Inventors: Jaime A. Valencia, Ransdall K. Smith, E. Lawrence Kimble, Scott D. Kelman
  • Purge to intermediate pressure in cryogenic distillation
    Patent number: 10274252
    Abstract: A system and method for an intermediate pressure vessel to receive a purge in a cryogenic distillation column system. The vessel operates at an intermediate pressure to reduce solidification of the purge. The cryogenic distillation column receives a natural gas having methane and acid gas. The column discharges an overhead stream rich in the methane, and a bottoms stream rich in the acid gas. An overhead system receives the overhead stream, and discharges a vapor methane product, and a cooled liquid for reflux to the cryogenic distillation column.
