Abstract
The H2O demand of various stages of a coal gasification process for co-generation of H and power was analyzed for an Integrated Gasification Combined cycle (IGCC). Three scenarios were studied: (a) combustion of all H to generate power, (b) combustion of 50% of total H for power generation with the remaining H available for other applications and (c) similar to scenario (b), but with 85% H availability. In case (a) a net power of 443.7 MW was generated with a thermal efficiency (HHV) of 37.5% and highest total H2O demand; in case (b) the net power is reduced to about half of (a) and in case (c) effective thermal efficiency was 34.4%. H2O consumption for power generation and H prodn. is increased by 31-36% if the process wastewater is not treated and recycled. on SciFinder(R)]
