Studies of Hydrodynamic Behaviour and Syn-Gas Production from Biomass Solid Wastes Using Fluidized Bed Gasifier: An ASPEN Plus Simulation
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2012, Vol 2, Issue 3
Abstract
: Fluidized bed gasification is one of the potential techniques for production of clean and ecofriendly fuel. ASPEN PLUS simulator is a strong tool for investigating the behavior of a process and it can be readily used to access various aspects like feasibility of an operation, effects of operating parameters on the performance of a gasifier. In the present work, the simulator has been used to simulate the effect of different system parameters (viz. Steam Flow rate, steam to biomass ratio, air flow rate, temperature, equivalence ratio, pressure) on the reaction kinetics mainly, on the product gas composition and carbon conversion efficiency of the fluidized bed gasification. Again hydrodynamic behaviour of the Fluidized Bed Gasifier (cold model) has been carried out with respect to different static bed heights and particle sizes of the bed material. The dolomite has been used as a bed material. Temperature was observed to be the most sensitive kinetic parameter thereby implying as the important aspect of gasification when operated under atmospheric pressure. Use of steam as a gasifying agent was observed to improve the syn-gas production.
