The results of the additional cases including the initial case (case 1), as previously described, are shown in Figure as represented by the calculated levelised cost. Key metrics are extracted from the data and summarised in Table . As seen from the Figure, case 3 to 1 generally display decreasing levelised cost due to higher capacity and hence benefit of economy of scale. The biggest effect is seen from 33.3 kg/s to 50 kg/s. At higher capacities, the effect of economy of scale diminishes due to more compressor units being needed since the maximum single unit capacity is exceeded. From Table it is observed that the lowest CAPEX shifts from liquefaction at 15 bar to pure compression up to 150 bar. The minimum power for case 1-3 is maintained just below the critical pressure, while for the lower capacity cases 2 and 3 the minimum LCOCC is now at a pure compression case, compared to case 1 where pumping from 87 bar was optimal. For case 4, which is calculated at 50 kg/s like case 2, it is interesting to note that, like case 2 (and 3), the minimum CAPEX is obtained for the pure compression case, but the lowest power is obtained at 46.5 bar. The lowest LCOCC is obtained at 96 bar, more in line with case 1. It is also interesting to note that case 4 in some regions leads to lower LCOCC than case 2 when liquefaction/pumping occurs below 60 bar and around 95-100 bar. The reason is the lower number of stages and hence less equipment in terms of coolers and scrubbers/coalescers. Although tempting, we cannot directly conclude that multi-impeller inline centrifugal compressors are better than integrally geared compressors, since the efficiency improvement of the integrally geared compressor has not been taken into account, neither the potentially lower CAPEX.
