Simulation of South African Corncob Gasification with Aspen Plus: A Sensitivity Analysis

Abstract:

Biomass is one of the significant fuel sources that can potentially contribute to the worlds energy demands. The most used technology that takes advantage of biomass heating value is still direct combustion which still suffers from significant inefficiencies creating therefore, the need for alternative processes to be analyzed. In this study Aspen Plus simulation package was used to develop a model for the gasification of corncob residues. The effects of equivalence ratio (ER) and steam to biomass ratio (SBR) on syngas composition and gasification temperature were investigated. The results showed that ER values of 0.34-0.35 and SBR values of 0.8 - 1 corresponding to a gasifiers temperature of 854-890°C were the optimum conditions for corncobs gasification.
