Abstract
This chapter discusses a study in which the simulation of a novel hydrogasification process for power generation was performed. This process has been proposed by the Zero Emission Coal Alliance, known as the “ZECA” process. To investigate the process, simulations of the process were performed using the Aspen Plus software package. The steady state process model was developed based on equilibrium and stoichiometric reactors. The model includes heat integration as well as material recycle. A base set of conditions was tested based on the literature description and a sensitivity analysis of some operating parameters was performed. It was concluded that the base case process shows lower efficiencies than those reported in the literature. The main difference was found to be the power generation in the solid oxide fuel cell (SOFC). The current model is believed to be a more realistic representation of the SOFC and, therefore, the overall process.
