The techno-economic summary of the proposed process base case using somewhat arbitrary, yet meaningful process parameters, is shown in Figure . The distribution of CAPEX for the main components is similar to that shown by Pérez-Fortes et al. They estimated compressors to be the biggest share of purchased equipment cost with 45% of the total, and heat exchangers to be the next biggest contributor with 40.6%. However, a discrepancy is the estimated cost of distillation and reactor, which was estimated to be only 1% and 1.5% by Pérez-Fortes et al., much lower than in the present study. Cordero-Lanzac et al. found compressors to be, by far, the biggest contributor to purchased equipment costs, which is amplified due to compression from 1 bar compared to the 51.2 bar assumed in the current study. Vaquerizo and Kiss 61 found similar trends with the following order of CAPEX contributions: Compressors, Heat exchangers, Reactor, Distillation. Very similar to the current study, also acknowledging compression from a lower pressure in the cited study.
