Simulationand Economic Analysis of Indirect Coal-to-Liquid Technology CouplingCarbon Capture and Storage.

Becausethe liquid fuel market in China is growing rapidly compared to thecapacity for liquid fuel production, interest of coal-to-liquid technologyis growing for producing liquid fuel. Several processes have not yetbeen industrialized. Among these, the Fischer–Tropsch (FT)process for fuel production from coal was chosen for simulation andanalysis. We consider carbon capture and storage (CCS) technologybecause of the importance of CO2emissions in climate change.Systems with and without CCS coupling were simulated using Aspen Plussoftware. We used the simulation results to estimate costs, investmentper unit of product, net present value, internal rate of return, andthe static investment recovery period as economic indicators. Theeconomic benefits of CCS technology were estimated in terms of CO2emission reductions cost and the cost for CO2capture.We also performed a price sensitivity analysis. The results revealthat CCS coupling to indirect coal liquefaction is economically feasible.With the pressure to limit CO2emissions, CCS couplingsystems for FT fuel production are expected to be competitive.
