    Abstract: Natural gas liquification systems (110) are provided wherein dependent trains (C) and (D) incuding only cryogenic heat exchanger systems (11) are serviced by common components (112), (113), (114), and (117) in the system (110) such that individual components need not be included in each dependent train (C) and (D) for servicing that function. Further, the common components (112), (113), (114), and (117) are positioned near the LNG storage tanks (120) which, in turn, are typically located a substantial distance from the trains (C) and (D). This significantly reduces capital costs and allows boil-off gas from LNG storage tanks (120) to be used for cooling in ddition to being used as a fuel gas.

    Abstract: A nitrogen stripper uses a shared distillation column that performs cryogenic distillation of multiple liquefied natural gas streams that are sourced from multiple cryogenic heat exchangers. The shared distillation column receives at least a part of an expanded liquefied natural gas stream, and discharges a liquefied natural gas stream through a bottom liquid outlet, and a reject vapour through an overhead vapour outlet. The expanded liquefied natural gas stream is obtained by expanding a plurality of pressurized liquefied natural gas streams discharged by the cryogenic heat exchangers. The distillation column is connected to a reboiler system, which has a separate heat exchange core for each one of the multiple liquefied natural gas streams that is dedicated to only one of these liquefied natural gas streams.
