2 Pengolahan Gas  Bhn Bakar Separasi GasSweetening Gas Drying Hg-removal Fraksinasi Pendinginan & Pencairan Kompresi Gas Bumi LNG CNG Gas Piping C1 C2+ LPG LPG Refrigerant Refrigerant Kondensat Kondensat SynGas GTL Fischer Trops

3 Volume Reduction LNG volume reduction: 600 times (all liquids at atmospheric pressure and –256 F) CNG volumes reduction: function of pressure and temperatures Higher pressure and lower temperature lead to higher volume reduction CNG volume reduction examples:  P = 2850 psig  206 times at 100 F & 280 times at 32 F  P = 1400 psig  103 times at 100 F & 133 times at 32 F
