Feasibility of generating electricity through gasification of sawmill residues in the North of Mexico
The feasibility of converting sawmill residues in electricity through gasification was evaluated in two ejido sawmills, Rocheachi and Tatahuichi, in the Guachochi municipality of Chihuahua State. The area has a semi cold climate, with temperature and precipitation annual means of 10,6 oC and 800 mm,...

| description | The feasibility of converting sawmill residues in electricity through gasification was evaluated in two ejido sawmills, Rocheachi and Tatahuichi, in the Guachochi municipality of Chihuahua State. The area has a semi cold climate, with temperature and precipitation annual means of 10,6 oC and 800 mm, respectively; the tree cover is dominated by pine and pine-oak communities with Pinus arizonica and P. duranguensis being the main species used for logging. The residues flow was estimated and its chemical composition and heating value characterized. The selected technology was the fixed bed downdraft gasifier; the costs and specifications data were provided by a Chinese supplier. The main assumptions were: 1,3 kgDM/kwh, 80% plant factor, electricity output sold for street lighting at 80% of commercial price. The financial viability was evaluated through the configuration of (100, 200, 400 and 800) kw systems and three scenarios: base, optimistic and pessimistic. The effect of additional revenues from carbon credits sold at the voluntary market at 4, 5 and 6 US$/tCO2 was assessed. The internal rate of return (IRR) increased consistently with increasing the systems’ capacity with the 800kw being the most economically attractive. without carbon credits, the 100 kw system showed no positive values at any scenario whereas the 800 kw system was the only one with positive IRR in all the scenarios with a range of 3% to 13%; the additional revenues from carbon credits added 2,3 and 2,9% to the low and high scenarios, respectively. In the context of the study, the systems evaluated would satisfy the additionality criteria required by the carbon market. |

Se evaluó la factibilidad de generar energía eléctrica a partir del uso de residuos del aserrío mediante la tecnología de gasificación en dos aserraderos ejidales, Rocheachi (RO) y Tatahuichi (TA), en el municipio de Guachochi, Chihuahua. El área se ubica en un clima semifrío, con medias anuales de temperatura y precipitación de 10,6 ºC y 800 mm, respectivamente; la vegetación está constituida por bosque de pino y pino-encino; las especies maderables son principalmente Pinus arizonica y P. durangensis. Se caracterizó el flujo de residuos, su composición química y su valor energético. Se seleccionó la tecnología de gasificación de cama fija con flujo hacia abajo con costos y especificaciones de un proveedor chino. Se asumió una conversión bioenergética de 1,3 kgMS/kwh y un factor de planta de 80%; el uso total de la electricidad sería alumbrado público municipal al 80% del costo de la tarifa normal. Se evaluó la viabilidad financiera de sistemas con capacidades a (100, 200, 400 y 800) kw bajo tres escenarios: base, optimista y pesimista. Se valoró el efecto de ingresos adicionales por venta de bonos de carbono en el mercado voluntario a (4, 5 y 6) US$/tCO2. La tasa interna de retorno (TIR) se incrementó consistentemente con la capacidad del sistema; el sistema a 800kw tuvo la mejor perspectiva económica. Los resultados fueron negativos y positivos en todos los escenarios para las capacidades de 100 kw y 800 kw, respectivamente. Sin bonos de carbono, la rentabilidad privada solo resulta aceptable (13%) en el sistema a 800kw en un escenario optimista. El impacto de los bonos se reflejó en incrementos en la TIR de 1,1 a 1,6% en el sistema de 400 kw y de 2,3 a 2,9% en el de 800 kw. Bajo estas condiciones, los sistemas evaluados reunirían los requisitos de adicionalidad que demanda el mercado del carbono.
