From Figure (C) the CAPEX of compression and refrigeration displays a similar trade-off as seen from the power in Figure . The pumping power increases from 15 bar up to just above the critical pressure due to decreasing density/increasing compressibility as partly discussed in the previous paragraph. As an end result, the CAPEX is the lowest when the liquefaction/pumping pressure is at its minimum at 15 bar. Then it stays high until after the critical pressure, from where it drops at around 80 bar and then drops until a pure compression case is obtained. The minimum CAPEX is 95.2 MM USD at a liquefaction pressure of 15 bar and the second lowest CAPEX is for the compression only case with 98.9 MM USD.
