摘要
Two models that can predict and simulate the performance of entrained bed coal gasifier were established by using the process simulator--Aspen Plus The models are characterized by handling solid materials directly rather than converting them into equivalent conventional components One model uses Aspen built in RGibbs model, and the other uses a user self defined model Both models were verified by the industrial data of three typical entrained bed gasifiers--Texaco, Shell and Destec Finally, the optimal equilibrium temperature ranges of different gasifiers were analyzed and discussed The analysis showed that the optimal equilibrium temperature of slurry feed gasifiers was lower than that of dry coal feed Shell gasifier, and the results of the slurry feed type gasifiers were more sensitive to equilibrium
Two models that can predict and simulate the performance of entrained bed coal gasifier were established by using the process simulator - Aspen Plus. The models are characterized by handling solid materials directly rather than converting them into equivalent conventional components. One model uses Aspen built-in RGibbs model, and the other uses a user self-defined model. Both models were verified by the industrial data of three typical entrained bed gasifiers - Texaco, Shell and Destec. Finally, the optimal equilibrium temperature ranges of different gasifiers were analyzed and discussed. The analysis showed that the optimal equilibrium temperature of slurry-feed gasifiers was lower than that of dry-coal-feed Shell gasifier, and the results of the slurry-feed type gasifiers were more sensitive to equilibrium temperature.
