The natural gas is cooled Ln in one or more heat exchangers using a first refrigerant from a first refrigerant circuit in which the first refrigerant is compressed in a 1-1 of first compressor driven by a first gas turbine having a first inlet air stream. The natural gas is liquefied using a second refrigerant, the 71. second refrigerant being compressed in a second compressor driven by a second gas turbine having a second inlet air stream. At least M one of the inlet air streams is chilled from about the respective dry bulb temperature to a temperature below the respective wet bulb ---, © temperature. Water contained in at least one of the chilled first and second air streams is condensed and separated therefrom. At least WD a portion of the first refrigerant is condensed or sub-cooled using the separated water. 1-1 0 ei O [Continued on next page] WO 2018/034815 Al MIDEDIMOMOIDEIREIHNIMIEHOHOMEHOIMIE MG, MK, MN, MW, MX, MY, MZ, NA, NG, NI, NO, NZ, OM, PA, PE, PG, PH, PL, PT, QA, RO, RS, RU, RW, SA, SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
