Noureddine Belhateche 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).

  • Liquid natural gas processing
    Patent number: 7475566
    Abstract: A process for the recovery of natural gas liquids (NGL) from liquefied natural gas (LNG) is disclosed. The LNG feed stream is subjected to a two stage separation process where the bottoms from the first stage separation containing C2+ hydrocarbons is split into two portions, with one portion being heated and used as a reflux during the second stage separation to recover the NGL product.
    Type: Grant
    Filed: July 25, 2005
    Date of Patent: January 13, 2009
    Assignee: Howe-Barker Engineers, Ltd.
    Inventors: Scott Schroeder, Kenneth Reddick, Noureddine Belhateche

  • Liquid natural gas processing
    Patent number: 6941771
    Abstract: A process for the recovery of natural gas liquids (NGL) (ethane, ethylene, propane, propylene and heavier hydrocarbons) from liquefied natural gas (LNG) is disclosed. The LNG feed stream is split with at least one portion used as an external reflux, without prior treatment, to improve the separation and recovery of the natural gas liquids (NGL).

  • LNG production in cryogenic natural gas processing plants
    Patent number: 5615561
    Abstract: A method and system for liquifying natural gas using a cryogenic process is described. The method is well suited for producing high methane purity natural gas which can be used as a vehicle fuel. The invention utilizes residue gas from a cryogenic plant as a natural gas feedstock. The natural gas feedstock is condensed by heat exchange with overhead gas from the demethanizer of the cryogenic plant. In the preferred embodiment of the invention the pressure of the condensed natural gas is reduced to a level at which it can be readily stored and transported by expansion through one or more Joule-Thomson valves.
