A study of multistage/multifraction column for fine particle separation. Quarterly technical progress report, second quarter April 1995--July 1995
Description: The overall objective of the proposed research program is to explore the potential application of a new invention involving a multistage column equipped with vortex-inducing loop-flow contactors (hereafter referred to as the multistage column) for fine coal cleaning process. The research work will identify the design parameters and their effects on the performance of the separation process. The results of this study will provide an engineering basis for further development of this technology in coal cleaning and in the general areas of fluid/particle separation. In the first year of the project, we completed equipment design, construction of the new column for hydrodynamic tests and gas holdup measurements. Also, we have initiated the determination of bubble size as part of the hydrodynamic measurements.
