Two options of carbon dioxide (CO2) utilized gas-to-liquids process mainly producing light olefins and Fischer-Tropsch (F-T) synthetic oils were implemented with the aid of Aspen Plus software. In the economic analysis, sensitivity analysis as well as break-even analysis was carried out. In addition, effects of several sensitive factors such as the prices of synthetic oil, olefin and natural gas (NG), capital investment, carbon tax and plant scale on the IRR of each option were analyzed in detail. It was shown that the two proposed options were economically feasible at the plant sacle of 40,000BPD, according to the indicators NPV, DPBP, and IRR. The two options would be more competitive at high carbon tax compared with conventional GTL processes. |
