TVA`s coproduction of electricity and fertilizer project

TVA is proposing to develop and commercially demonstrate the coproduction of electricity and fertilizer using integrated gasification/combined cycle (IGCC) technology. The Coproduction Demonstration Project (CDP) will show that coproduction of chemicals with electricity can economically and environmentally enhance the production of electric power from coal. The proposed CDP will be a nominal 250-M plant. During normal operation, the CDP will produce about 150 MW of base-load capacity and 1000 tons per day (TPD) of urea. Sulfur is recovered either as sulfuric acid or elemental sulfur. During peak power demand, the fertilizer capacity can be bypassed, and the full 250 MW can be produced. Subsequent IGCC/fertilizer coproduction (IGCC/F) plants may convert only 20 to 25 percent of the plant`s capacity as fertilizer or other chemicals, depending on optimum IGCC/F operating conditions. The coproduction of electricity and fertilizer allows the continuous operation of the capital intensive gasification-related process units at 100-percent capacity, while varying the amount of electricity produced from 60 percent to 100 percent of rated capacity. Coproduction also will further reduce the annual revenue requirements for power generation by the coproduction of the higher valued fertilizer coproduct. Since nitrogen fertilizers are produced from natural gas, the real escalation of natural gas prices in the 1990s is expected to result in significant price increases in natural gas-based chemicals, especially fertilizers. The overall risk of producing revenues is reduced because two countercyclic coproducts are produced. Electricity has peak demands in the summer and winter while fertilizer`s peak demand is in the spring.
