Electroacoustic Dewatering (EAD) capitalizes on the adaptation of synergistic effects of electric and acoustic fields to commercial coal dewatering systems, such as belt filter presses. The Battelle project for demonstrating the potential for commercial application of the EAD process for coal has the following objectives: to validate the expected technical feasibility and energy conservation/economic benefits of the EAD process as applied to fine (-100 mesh) and ultrafine (-325 mesh) coal; and to obtain data from a continuous, process research unit (PRU) in order to conduct a reliable economic analysis and to design commercial EAD filters as well as to promote adaptation of the process by the coal preparation industry. During this quarter, efforts were directed towards completion of PRU operation. The paper describes results from field testing on miners 325 mesh Upper Freeport coal and discusses the effects of experimental factors on final cake solids and on delta solids and linear regression models. 4 figs., 4 tabs.
