Abstract: A conduit seal assembly includes an outer conduit having a first end with a first opening and a second end, opposite the first end, with a second opening. A first seal is positioned in the first opening for resisting a first temperature, and a second seal is positioned in the second opening for resisting a second temperature less than the first temperature. The first and second seals define a cavity and provide an air-tight seal of the cavity, and the assembly includes a monitoring assembly configured to sense a characteristic in the cavity.

Abstract: Methods and systems for liquefying natural gas using environmentally-friendly low combustibility refrigerants are provided. Methods of liquefaction include cooling a fluid in an LNG facility via indirect heat exchange with an environmentally-friendly low combustibility refrigerants that are propane, ethane and methane mixed with small amounts of fluorinated olefin, but still within close proximity to the boiling points of the pure refrigerants such that the mixed refrigerants can still be used in an optimized cascade process.
