  • Patent number: 9593015
    Abstract: An enrichment apparatus and process for enriching a hydrogen sulfide concentration in an acid gas stream to create a hydrogen sulfide rich stream for feed to a Claus. The enrichment apparatus comprises a hydrocarbon selective separation unit operable to separate the acid gas stream into a hydrocarbon rich stream and a purified acid gas stream, wherein the acid gas stream comprises hydrogen sulfide, carbon dioxide, and hydrocarbons, a hydrogen sulfide selective separation unit operable to separate the purified acid gas stream to create the hydrogen sulfide rich stream and a hydrogen sulfide lean stream, the hydrogen sulfide rich stream having a concentration of hydrogen sulfide, and the Claus unit operable to recover sulfur from the carbon dioxide lean stream. The enrichment apparatus can include a carbon dioxide selective separation unit in fluid communication with the hydrogen sulfide selective separation unit, operable to separate the hydrogen sulfide rich stream.

  • Patent number: 9393540
    Abstract: A membrane-integrated hydration reactor that is operable to produce an associated alcohol product from an olefin using water includes a solid acid olefin hydration catalyst in a production zone and a hydrophilic membrane operable to selectively permit pervaporation of water one-way and not permit pervaporation of the associated alcohol or permeation of the olefin at olefin hydration process conditions in a separations zone. The production zone is operable to form a production zone product mixture made of the associated alcohol and any unreacted water. The associated separations zone is operable to form and produce both the associated alcohol product and a pervaporated water product from the production zone product mixture. A method of olefin hydration for forming an associated alcohol product from an olefin using water uses the membrane-integrated hydration reactor at olefin hydration process conditions.

  • Patent number: 9267429
    Abstract: An apparatus and process for reducing vehicle emissions by converting exhaust gases to hydrocarbon fuel. The apparatus and process supplement conventional emission control techniques to further reduce vehicle emissions of harmful substances. The apparatus includes a heat exchanger to extract thermal energy from exhaust gases of a combustion engine that powers propulsion of a vehicle, a membrane separator to separate water and carbon dioxide from the exhaust gases, and a catalytic reactor comprising a nano catalyst. The catalytic reactor receives the water and the carbon dioxide from the membrane separator, contains a reaction of the water and the carbon dioxide that produces hydrocarbon fuel and is facilitated by the nano catalyst, and uses the thermal energy from the heat exchanger to stimulate the reaction. The catalytic reactor is contained within a body of the heat exchanger to facilitate the transfer of thermal energy.
