“…En la Tabla 2 se presenta el análisis último en base seca de los RSU generados en Medellín, considerados adecuados para su aprovechamiento energético. Debido a la ausencia de información sobre la composición elemental de los RSU generados en Medellín, el análisis último, contenido de ceniza y humedad fueron estimados a partir de datos reportados en literatura científica (Ahmed y Gupta, 2009;Balcazar, Dias, y Balestieri, 2013;Haydary, Susa, y Dudáš, 2013;Rodrigues, Marcilio, Trierweiler, Godinho, y Pereira, 2010), en función de las fracciones másicas. El poder calorífico inferior en base seca fue estimado usando la correlación presentada por Shi, Mahinpey, Aqsha, y Silbermann (2016), para RSU con un R 2 =0,938.…”

ResumenSe determinan estrategias termodinámicas para la conversión energética de Residuos Sólidos Urbanos (RSU) en plantas de incineración bajo condiciones sub-estequiométricas. La valoración energética de RSU es una alternativa para mitigar los impactos ambientales que genera su disposición final, siendo la producción de RSU de la ciudad de Medellín (Colombia) de aproximadamente 1800 ton/día. El análisis se lleva a cabo mediante un modelo en equilibrio termoquímico del proceso de gasificación, donde se estudia el efecto del contenido de humedad y la relación equivalente combustible-aire en el proceso termoquímico. El potencial energético de los RSU de la ciudad es de 28 a 44 MW eléctricos. Las estrategias termodinámicas para aprovechar energéticamente los RSU en plantas de incineración bajo condiciones sub-estequiométricas, de modo autotérmico y evitando la fusión de cenizas, establecen que el proceso se debe llevar a cabo con una relación equivalente combustible-aire de gasificación entre 1.5 y 3.3, independiente del contenido de humedad de los RSU. Palabras clave: valoración energética; residuos sólidos urbanos; equilibrio termoquímico; gasificación AbstractIn this study, thermodynamic strategies are determined for the energy conversion of Municipal Solid Wastes (MSW) in incineration plants under sub-stoichiometric conditions. Energy generation from MSW is an alternative to mitigate the environmental impacts derived by their final disposal, being the production rate of MSW in Medellin city (Colombia) of about 1800 ton/day. The analysis is conducted by means of a thermochemical equilibrium model of the gasification process, where the effect of moisture content and fuelair equivalence ratio on the thermochemical process is studied. The energy potential of MSW from the city is between 28 and 44 MWe. The thermodynamic strategies for energy recovery from MSW in incineration plants at sub-stoichiometric conditions, under auto-thermal regimens and avoiding ash fusion, establish that the process must be carried out with a fuel-air equivalence ratio between 1.5 and 3.3, regardless of the moisture content of the MSW.

“…The conversion of hydrocarbons to non-condensing species was efficient; according to GC-MS analysis there was only 1.57 mg of organic compounds in the aqueous condensate (approximately 0.012% of the gasified mass of the sample). The main components of this phase were: fluoranthene (34% of the organic species), naphthalene (27%) and phenanthrene (15%).The volume and heating value of gas was calculated assuming that the gasified packaging was composed of 85.62% organic fraction (including 47.33% C, 7.71% H, 30.26% O, 0.26% N and 0.06% S) [3]; the rest was aluminum and ash. According to the equilibrium model, gasification of 100 kg of the carton packaging would provide 239 m 3 of the dry gas (59 mol.% H2, 39% CO, 1% CO2 and 1% CH4) with HHV of 11.6 MJ/m 3 .…”

Steam gasification for waste valorization with energy recovery

Steam gasification seems a promising technology of waste transformation since the steam is the only oxidizing reagent in the process and gaseous carrier of volatiles. Gasses are equilibrated at high temperature for conversion to the H2-rich syngas. After this step, the excess of steam condenses during cooling, together with non-converted tars, oils and fine particles. Condensing steam efficiently absorbs hydrogen bromide and hydrogen chloride. The use of steam eliminates carbonaceous residue from the solid mineral/metal product, which is convenient for further processing (for example extraction of metals). The syngas and the solid residue are generally the only products of gasification, because aqueous condensate may be returned to the process together with non-volatile hydrocarbons and sediments. The process was illustrated by laboratory scale gasification experiments with a) carton packaging, b) abrasive disc, c) pork bones, d) Cu multiwire cable e) PC/AT card and f) inverter (PCB board). The mineral/metal products of gasification may be considered as a raw materials for further processing, including typical routes of metals recovery. There is no direct emission to the atmosphere from the process. However, providing the energy from the syngas back to the reactor as well as the energy balance of steam condensation and recirculation of condensate to the reactor need careful analysis.

“…Pyrolysis was applied, over the years, to different substrates, e.g. to carbonaceous materials, such as coal or wood [7,8], biomasses [9,10], municipal solid waste [11], packaging [12,13] and tires [14,15] for energy and valuable chemicals recovery. Thanks to its versatility the process was also applied to the pyrolysis of carbon fiber composites (CFRPs) where energy recovery to sustain the process is coupled to the recovery of reusable carbon fibers [16,17,18].…”
