Simulation of municipal solid waste gasification in fixed bed reactor

Полный текст:


The objective of this work is simulating municipal solid waste gasification in fixed bed reactor. A comprehensive process model developed to simulate municipal solid waste (MSW) gasification in fixed bed reactor using an Aspen Plus  simulation .To predict and analyze the  municipal  solid  waste  pyrolysis and gasification process in an updraft fixed bed more veritably and appropriately, numerical modeling based on Gibbs energy minimization was executed using the Aspen plus software v(9). Rstoic is a block that can be used to simulate a reactor with the unknown or unimportant reaction kinetic  that  will  describe  drying  section(moisture evaporated).The Ryield model was  describe the pyrolysis section, while the Rgibbs model was used  for  gasification section individually .The  proposed  model is used to forecast and analyze target performance  parameter including syngas composition, lower heating value and carbon conversion rate under different conditions of  gasification temperature , and ratios. The results indicate that  is a good agreement between data and simulated data obtained using this model .The predicted  optimum  gasification temperature is about approximately 750°C, and the best ratio  of air equivalent ratio is around 0.2 and feed rate 200 kg /hr.
