Clean liquid fuels from MSW
- EnerTech Environmental, Inc., Atlanta, GA (United States)
The need for a cost effective and cleaner method of Municipal Solid Waste (MSW) disposal hardly needs emphasizing. With funding through the US EPA and US DOE-METC, EnerTech demonstrated its SlurryCarb{trademark} process for producing homogeneous, pumpable fuels from Refuse Derived Fuel (RDF) with continuous pilot plant facilities, and characterized flue gas and ash emissions from combustion of the carbonized RDF slurry fuel. Pilot scale slurry carbonization experiments with RDF produced a homogeneous pumpable slurry fuel with a Higher Heating Value up to approximately 6,600 Btu/lb at 51.7 wt% total solids. The viscosity of this carbonized RDF slurry fuel was approximately 500 cP {at} 100 Hz decreasing, and ambient temperature. Also, pilot scale slurry carbonization experiments extracted up to approximately 94% of the feed RDF chlorine content as chloride salts. Atmospheric combustion of the carbonized RDF slurry fuel produced a carbon burnout exceeding 99.9%, with excess air as low as 15%. CO emissions averaged below 16 ppm (corrected to 7% O{sub 2}), while HCl and SO{sub 2} emissions were below 17 and 40 ppm, respectively, without acid gas scrubbing. NO{sub x} emissions depended on combustion temperature and averaged between 82--211 ppm, without selective noncatalytic or catalytic reduction. In addition, mercury emissions were measured at 0.003 mg/dscm. Combustion ash was non-hazardous, with low leaching characteristics, based on a TCLP analysis.
