Green Production of Hydrogen from Excess Biosolids Originating from Municipal Waste Water Treatment
Technical and economic aspects of equivalent hydrogen (moles of H 2 +moles of CO potentially converted to H 2 ) production from biosolids produced in wastewater treatment are evaluated in this paper. ASPEN+ simulation of the gasification of biosolids and coal provides the basis for the analysis of the technical performance of a gasification process. The General Electric (GE, formerly Texaco) Gasifier was chosen for the study. The solids are assumed to be slurried as 50 wt% or 70 wt% solids (typical and maximum attainable) as feed streams for the gasifier with water. In this study, the incremental raw material costs (feed+oxygen) for gasification plants producing the same annual quantity of H 2 from coal and/or biosolids are compared. It may be seen that under the conditions of this study, the estimated cost of H 2 production may be significantly reduced when biosolids are included in the feed materials to gasification, but only when the avoided disposal costs of the biosolids are considered.
