| Popis: | We compare different approaches for the preparation of carbon monoxide-rich synthesis gas (syngas) for Fischer&ndash Tropsch (FT) synthesis from carbon dioxide (CO2) using a self-consistent design and process simulation framework. Three alternative methods for suppling heat to the syngas preparation step are investigated, namely: allothermal from combustion (COMB), autothermal from partial oxidation (POX) and autothermal from electric resistance (ER) heating. In addition, two alternative design approaches for the syngas preparation step are investigated, namely: once-through (OT) and recycle (RC). The combination of these alternatives gives six basic configurations, each characterized by distinctive plant designs that have been individually modelled and analyzed. Carbon efficiencies (from CO2 to FT syncrude) are 50&ndash 55% for the OT designs and 65&ndash 89% for the RC designs, depending on the heat supply method. Thermal efficiencies (from electricity to FT syncrude) are 33&ndash 41% for configurations when using low temperature electrolyzer, and 48&ndash 59% when using high temperature electrolyzer. Of the RC designs, both the highest carbon efficiency and thermal efficiency was observed for the ER configuration, followed by POX and COMB configurations. |
