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: Ø P = 2850 psig 206 times at 100 F & 280 times at 32 F Ø P = 1400 psig 103 times at 100 F & 133 times at 32 F
