This paper presents a thermodynamic model for the estimation of impurities in the raw synthesis gas and in the slag resulting from gasification of solid waste. Based on thermodynamic equilibrium calculations and mass balances, the model takes into account the possibility of each impurity becoming an oxide, a chloride, or remaining in its elemental form. The model includes a comprehensive set of thermodynamic data for a wide variety of chemical species used to estimate the equilibrium constants. By solving the equilibrium reaction equations, the model predicts which pollutants are formed and in what amounts as well as their distribution in the raw synthesis gas and in the slag. Predicting the distribution and fate of these pollutants is particularly important for the design of a gas cleaning system for the raw synthesis gas and for deciding on the disposal options of the slag. The model can be applied to different waste materials, including municipal solid waste, mixed plastics waste, auto-shredder residue (ASR) and biomass. A comparison between the model predictions and the operational data from a commercially-available gasification process (Thermoselect) shows a close agreement between the estimated and real data. |
