Summary:

Because the coal gas produced from modern coal gasifiers can be purified to be compatable with slurry-phase F-T systems, it is feasible to integrate F-T synthesis with an IGCC facility to coproduce clean electric power and excellent quality nation fuels with high overall efficiency. This is similar in concept to coproducing electric power and methanol in a once-through process, and the feasibility of this concept has been extensively studied by EPRI. In the once-through methanol concept, the methanol could be used as peaking fuel in the power plant or sold as a chemical or fuel. This paper analyses this once-through F-T concept to determine the cost and efficiency advantages of a facility that coproduces power and transporation fuels compared to stand-alone IGCC and F-T facilities. The results of this analysis indicate that a coproduction facility can reduce the required selling price of transportation fuels by up to 15 percent compared to stand-alone facilities, and do so with no additional cost of electric power over the stand-alone IGCC case. This cost savings can also be achieved at a higher overall efficiency. Such a coproduction facility may allow coal-based IGCC technology to penetrate more rapidly into the marketplace. An independent power producer (IPP) may find this concept attractive since it allows the flexible production of power (for load following) and fuel as dictated by demand with no overall loss of plant capacity. In addition, the risk of plant investment is lowered by producing products for two markets.
