CLEAN AND EFFICIENT UTILIZATION FROM AGRICULTURAL RESIDUES

Phase I research proved the feasibility of EnerTech's Slurry Carbonization technology for economically producing clean and marketable fuels from high-moisture agricultural residues and wastes, especially animal manures. The Slury Carbonization technology effectively transformed low-grade animal residues, through a moderate temperature and pressure carbonization process, into a uniform and especially salt-free pumpable slurry fuel with a heating value substantially higher than the raw waste. The specific objectives of determining the fuel characteristics of the product carbonized slurry fuel versus the feed material (animal waste) and the process conditions were achieved during Phase I. The overall objective of Phase II is to develop design data for a commercial-scale plant. The specific Phase II objectives and work plan have been structured to provide the technical information necessary for scale-up, including combustion experiments to further characterize trace emissions and ash generated. It is anticipated that Phase II will establish the EnerTech process as an economically and environmentally desirable method for disposal of pig manure and other similar animal waste. Development work plans have been structured to compile the necessary scientific and engineering data to construct an integrated demonstration facility in Phase III.
