Gas Sweetening Gas Drying Hg-removal Pengolahan Gas Bhn Bakar C1 Pendinginan & Pencairan LNG Gas Bumi Kompresi CNG Separasi Fraksinasi Gas Piping • LPG • Refrigerant • Kondensat C2+ SynGas Fischer Trops GTL
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
Terrestrial CNG Technology: TransCanada
Marine CNG Technology: VOTRANS (EnerSea) Using bundles of steel pipes containing the gas under optimized Pressure & Temperature
Marine CNG Technology: Coselle (Williams) Incorporating spools of coiled tubing
CNG gas quality standard California C1 88.0 % min C2 6.0 % max C3 and higher HC 3.0 % max C6 and higher HC 0.2 % max Hydrogen 0.1 % max CO 0.1 % max Oxygen 1.0 % max CO2+N2 1.5 – 4.5 % Sulphur 16 ppmv (max)
