Abstract

Natural gas liquefaction systems are provided wherein dependent trains including only cryogenic heat exchanger systems are serviced by common components in the system such that individual components need not be included in each dependent train for servicing that function. Further, the common components are positioned near the LNG storage tanks which, in turn, are typically located a substantial distance from the trains. This significantly reduces capital costs and allows boil-off gas from LNG storage tanks to be used for cooling in addition to being used as a fuel gas.
