INVESTIGATION OF MICROALGAE GASIFICATION UNDER STEAM ATMOSPHERE IN DOWNDRAFT GASIFIER BY USING ASPEN PLUS®

Prediction of Rice Husk Gasification on Fluidized Bed Gasifier Based on Aspen Plus

A biomass gasification model was developed using Aspen Plus based on the Gibbs free energy minimization method. This model aims to predict and analyze the biomass gasification process using the blocks of the RGibbs reactor and the RYield reactor. The model was modified by the incomplete equilibrium of the RGibbs reactor to match the real processes that take place in a rice husk gasifier. The mo...

Simulation of Biomass Gasification in Fluidized Bed Using Aspen Plus

Gasification is a thermo-chemical process to convert carbon-based compounds such as biomass and coal into a gaseous fuel. Among the various types of gasification methods, fluidized bed gasification is one which is considered as more efficient method than others as biomass is fluidized in a mixture of air/oxygen and steam. In the present study, a comprehensive steady state process model has been...

Biomass Downdraft Gasifier Controller Using Intelligent Techniques

Experimental Studies on Gasification of Pine Wood Shavings in a Downdraft Biomass Gasifier

Biomass is the oldest form of energy used by human beings, mainly in the form of wood. It is a renewable source of energy and has many advantages from an ecological point of view. The direct combustion of biomass generates concern among environmentalists, as it is incomplete and inconsistent and may produce organic particulate matter, carbon monoxide and other organic gases. Biomass gasificatio...

Gasification of Densified Sludge and Wastepaper in a Downdraft Packed-Bed Gasifier

The co-disposal of densified sludge and wastepaper in a co-current flow packed bed gasifier represents new application of the thermal gasification process. Advantages of this technolo a gy include lower costs than other incineration or pyrolysis technologies, simple construction and operation, and the ability to a variety of fuels including agricultural wastes and other b.iomass materials in ad...
