  • Patent number: 12246805
    Abstract: An offshore LNG processing plant includes a first module including a personnel accommodation facility on a first vessel, a second module including a gas treatment facility on a second vessel, and a third module including a gas liquefaction facility on a third vessel. Each of the first, second, and third modules are assembled on the corresponding vessels, and then transported to an offshore location in a body of water, such as a river, a lake, or a sea. At the offshore location, each vessel deploys legs to the bed of the body of water to raise a hull of each vessel out of the water. The first module is then coupled to the second module, and the second module is coupled to the third module. A fourth module on a fourth vessel is coupled to the third module to provide LNG storage.

  • Patent number: 10443927
    Abstract: Processes and systems are provided for recovering a liquid natural gas (“LNG”) from a hydrocarbon-containing gas. More particularly, the present invention is generally related to processes and systems that optimize the chilling efficiencies of an LNG facility through the utilization of an auxiliary refrigeration cycle. Additionally, the present invention is also generally related to the rerouting of mixed refrigerants in a closed-loop refrigeration cycle in order to optimize the chilling efficiencies of the LNG facility.

  • Patent number: 10436505
    Abstract: Processes and systems are provided for recovering a liquid natural gas (LNG) stream from a hydrocarbon-containing feed gas stream using a single closed-loop mixed refrigerant cycle. In particular, the processes and systems described herein can be used to separate methane from carbon monoxide and hydrogen, which are common components in synthesis gas and other hydrocarbon-containing gases.

  • Patent number: 6295833
    Abstract: A closed loop single mixed refrigerant process and system wherein the process efficiency is increased by increasing the temperature of liquefied material produced in a heat exchange refrigeration zone and thereafter cooling the liquefied material by flashing a portion of the liquefied material to produce a cooler liquefied material and a flash gas a portion of which is recycled to the heat exchange refrigerator. The process and system provide increased process efficiency and flexibility.
