Modeling Of Zero-emission Power Generation System Of Biomass Gasification Based On AspenPlus

Observation of the increased concentration of carbon dioxide in the atmosphere and the global warming effect has made prevention of carbon dioxide emission very important nowadays.The model proposed in this paper combined biomass gasification(the gasification agent is CO₂),chemical-looping-combustion and fluidized bed technology,for the goal of eliminating the emission of CO₂.This model was developed using AspenPlus,and the sensitivity of key parameters of the system was analyzed.Through the simulation it can be found that the total system efficiency increases with the increase of the CO₂ flow.The influence of air flow is similar to the CO₂,and the increase of NiO amount reduces the total efficiency.This AspenPlus model and system analyses provides the basic research of developing the new way of biomass power generation and eliminating of CO₂ emission.
