This report gives the analytical results from wastewater samples collected from the scrubber at the Institute of Gas Technology's U-GAS pilot plant under three different sets of operating conditions, including start-up and steady-state. This work was performed to provide data that could be used in the design of wastewater treatment facilities for the proposed Memphis Industrial Fuel Gas Demonstration (IFGD) plant that is to use the U-GAS gasifier. The scrubber effluent was analyzed for trace elements, inorganic constituents and organic species (including hazardous organics) in order to determine its composition. For purposes of comparison to the operation of other gasifier operating conditions, the results from one of the samples collected was normalized to pounds of constituent produced per 1000 pounds of coal consumed. Results indicate that the U-GAS gasifier produces a fairly clean scrubber effluent stream. Ammonia is the major potential pollutant at significant concentrations. Aluminium, boron and iron are found at appreciable concentrations, but there are indications that iron is associated with particulate matter and easily removed from the waste stream. Polycyclic aromatic hydrocarbons (PAH) comprise the majority of hazardous organics present in the wastewater, but their concentration is low. PAH concentrations, moreover, along with the other organics present, substantially decrease with better coal conversion efficiency, as pressure is increased and the gasifier reaches steady-state conditions.
