PROCESS SIMULATION OF AN INTEGRATED COKE DRY QUENCHING COMBINED GASIFICATION

In this paper, an integrated coke dry quenching combined gasification system using coke oven gas and steam to quench the incandescent coke is proposed. The distinct advantages of the system include energy conservation, pollution reduction, coke quality improvement and full use of resources. Based on the minimization of the Gibbs free energy, the flow rate and composition of the syngas are predicted. At the same time, the effects of the coke oven gas flow rate and the steam consumption on the flow rate and composition of the syngas as well as exergy efficiency is analyzed by using PRO/II simulator. Finally, the effects of the coke oven gas flow rate and the steam consumption remarkably on flow rate and composition of the syngas and exergy efficiency are investigated.
