The biomass gasification is one of the largest chemical transformation procedures of heat effectiveness. Numerical simulation is a significant instrument for studying biomass gasification. The numerical simulation of biomass gasification technologies at work and overseas is evaluated in this article. At the same moment, two commercial analysis applications (Aspen Plus and Fluent) applied in chemical processes were primarily implemented, both of which be there investigated and contrasted. In conclusion, it was suggested that is a better simulation outcome for biomass gasification could be obtained by implementing the Aspen Plus in combination with Fluent.

Introducción− En las industrias de extracción de aceite de palma, por cada 10 ton de racimos de fruto fresco (RFF) procesados, se producen cerca de 3700 kg de residuos con Poder Calorífico Inferior (PCI) de alrededor de 18 MJ/kg. Estos residuos, compuestos principalmente por racimos de frutos vacíos, fibra y cuesco podrían ser utilizados para generación de electricidad o vapor supliendo de manera parcial o total la demanda de energía de las empresas del sector. De estos residuos, el que mejor se adapta para generación de electricidad a partir de biomasa, en rangos menores a 2MW, es el cuesco, el cual puede ser utilizado en sistemas de gasificación de lecho fijo acoplados a motor generador. Objetivo− Evaluar el potencial energético del cuesco de palma de aceite para la generación de electricidad utilizando gasificación en lecho fijo acoplada a motor generador. Metodología− Se desarrolló un modelo de gasificación en equilibrio químico que permite estimar la composición de gases y, por tanto, el potencial energético de los residuos de cuesco de palma. Resultados- El modelo permite analizar variaciones en el proceso debidas a cambios en agente gasificante (AG), composición y contenido de humedad de la biomasa. Los resultados son validados utilizando información reportada en la literatura. El modelo es utilizado para analizar el potencial energético de los residuos de una planta extractora típica de 10000 ton RFF/mes. Conclusiones− Se estima que por cada 22 kg/h de cuesco se producen aproximadamente 70 kg/h de gas con composición promedio de 12,5 % H2, 21,8 % CO, 9,5 % CO2, 56 % N2 y trazas de CH4 c on p oder c alorífico i nferior ( PCI) c ercano a 4 ,1 M J/Nm3. Lo anterior, cuando el proceso opera con una relación de equivalencia (ER) de 0,33 y humedad de biomasa de 15 % w.t. Así, utilizando el gas como combustible para un conjunto motorgenerador, la demanda eléctrica de una planta extractora de aceite puede ser suplida en su totalidad, empleando menos del 85 % del cuesco resultante del proceso.

The demand for energy from biomass gasification is increasing due to the depletion of fossil fuels and serious environmental issues. Due to this, usage of individual biomass in a gasifier is not sufficient to meet the demand in rural areas. However, an enormous study have been reported on the gasifier with single biomass as working fuel. In addition, only a few works have been carried out on biomass blends in a gasifier through equilibrium modelling and experimental approach. The numerical simulation for the biomass blends are in scarce. Hence, in this study, a numerical and experimental studies were conducted on a 40kWth downdraft biomass gasifier to find out the possibility of rubber seed kernel shell and cassava stalk biomass with different blend ratio. The species-transport CFD model is used for numerical simulation with the k-ε turbulence model. The effect of species concentration, higher heating value and conversion efficiency with respect to different equivalence ratio have been observed. The simulated results were also validated through experimentation. Among different blending ratio 80:20 blend shows better performance. The result reveals that the species concentration and higher heating value at 0.2 equivalence ratio has an average value of CO-23.5%, H 2-19.2%, CH 4-3.1% and 6.62 MJ/Nm 3 with an efficiency of 58.23% respectively. The viability of using the species transport model for biomass blends is confirmed.
