SIMULATION OF A COAL HYDROGASIFICATION PROCESS WITH INTEGRATED CO_2 CAPTURE

摘要

The simulation of a novel hydrogasification process for power generation has been performed. This process has been proposed by the Zero Emission Coal Alliance and is known as the ZECA process. A detailed description including performance of the process is not readily available in the literature. Considering the novelty and the claim about the performance of this process, it was decided to investigate this promising system.rnSimulations 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.
