Prediction of Syngas and Hydrogen Production by Gasification using Industrial Factory By-products

  • 37

In this study, an appropriate prediction model was derived using a commercial code such as ASPEN PLUS, and the predicted value and the predicted value of the self-developed Excel-based prediction program were compared and considered. The gasification reaction conditions applied to the prediction program for gasification and melting were compared and analyzed for three prediction programs for the case of using the main gasification reaction equation(6 types), the case of using the water gas displacement reaction and the case of using the chemical equilibrium. As a result of comparative analysis, the predicted values of gasification characteristics were almost identical for the three reaction conditions. As the case of applying the six main gasification reaction equations and the prediction model applying the water gas displacement reaction yielded the same result, it was reasonable to predict the water gas displacement reaction conditions. The agreement between the predicted results by the analysis of the dedicated program of the gasification furnace and the results of the gasification and melting experiment was examined. For the prediction of syngas production, the error rate of Case D-1, which applied the waste calorific value analysis value, was the lowest at 5.2%. It was reviewed based on the synthesis gas flow rate of 170Nm3/hr, CO 38.75% and H2 24.72%, derived using the Dulong equation of the Excel-based syngas production prediction program. This is predicted to be capable of producing 2,215Nm3/hr of syngas with 1ton of by-product of industrial plants. It can produce 89.2Nm3/hr of high purity hydrogen from 80kg of industrial plant by-products. It is predicted that one ton of industrial plant by-products can produce 100kg of hydrogen.
