Jeffrey Alan Kabin 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).

  • Method of removing dimethyl ether from an olefin stream
    Patent number: 7678958
    Abstract: This invention is directed to a method of removing dimethyl ether from an olefin stream. The method includes distilling the olefin stream so that the dimethyl ether is separated out of the olefin stream with propane. The olefin stream can then be further distilled to provide a polymer grade ethylene stream and a polymer grade propylene stream, with each stream containing not greater than about 10 wppm dimethyl ether.

  • Process for separating carbon dioxide from an oxygenate-to-olefin effluent stream
    Patent number: 7135604
    Abstract: The present invention is a process for removal of carbon dioxide from a reactor effluent stream comprising water, carbon dioxide and olefin(s), where a portion of the carbon dioxide is removed in a quenching step with a quench medium and more carbon dioxide is removed by contacting the quenched effluent stream with an alkaline stream. A portion of the alkaline stream is added to the quench medium.

  • Method and apparatus for controlling effluent composition in oxygenates to olefins conversion
    Patent number: 7115791
    Abstract: A process for controlling an oxygenates to olefin reactor is disclosed which comprises: contacting oxygenate-containing feedstock, e.g., methanol, in a reaction zone in the presence of a molecular sieve oxygenate to olefins conversion catalyst under conditions sufficient to provide an olefins-containing effluent containing alkyl alcohol and dialkyl ether, e.g., methanol and dimethyl ether; analyzing a single gas phase of the effluent determine alkyl alcohol concentration and dialkyl ether concentration; and adjusting reactor conditions, e.g., WHSV, as a function of alkyl alcohol concentration and dialkyl ether concentration, as necessary to provide a substantially consistent effluent composition. A corresponding apparatus for carrying out the process is also provided.

  • Process for operating a quench device in an oxygenate-to-olefin production unit
    Patent number: 7102049
    Abstract: The present invention is a process for producing olefin(s) from oxygenates that is more effective than previously known processes at removing carbon dioxide from the effluent stream by operating a quench tower at a pH greater than 7.0.

  • Process for separating and recycling oxygenate(s) to an oxygenate-to-olefin reactor
    Patent number: 7005555
    Abstract: The present invention is a process for producing olefin(s) from oxygenate(s). The process removes oxygenate(s) including carbon dioxide in the bottoms of the quench stream and recycles the oxygenate(s) back to the reactor. Carbon dioxide is removed from the quench bottoms before returning oxygenate(s) in the quench bottoms stream to the reactor.
