Abstract

A preliminary engineering, geological, and hydrological environmental assessment of a proposed 250 MMSCFD dry ash Lurgi coal gasification facility is discussed.

The facility's emission spectrum is examined on the basis of the proposed design and empirical data. This system utilizes approximately 13 million tons of lignite and 17,000 acre feet of water per year and consumes 6500 tons of oxygen per day. The results of the study indicate that the major gaseous effluent is CO2, that the federal limits on SO2 effluent may be met, and that the atmospheric degradation criterion will be the most difficult one to meet.

The fate of trace elements during the gasification process is discussed. Available preliminary data indicate that the majority of the trace elements will be concentrated in and leave the system with the ash.

The probable hydrological and geological impacts pertinent to ash and sludge disposal and water table depression are discussed. The results of the study indicate that the water table will be depressed during mine operations and that some groundwater pollution will occur due to waste disposal.
