Development of a gas-promoted oil agglomeration process. Technical progress report, December 1, 1993--February 28, 1994
The overall purpose of this research project is to carry out the preliminary laboratory-scale development of a gas-promoted, oil agglomeration process for cleaning coal using model mixing systems. A model mixing system has been previously designed and constructed for conducting oil agglomeration tests in such a way that agitator speed and torque can be measured as well as agglomeration performance. Equipment is also provided for monitoring the progress of agglomeration during a batch test. This equipment includes a photometric dispersion analyzer for measuring the turbidity of the particle suspension. In order to measure the turbidity a small stream of material is withdrawn from the mixing tank and conducted through an optical cell associated with the photometric dispersion analyzer. The material is then returned to the mixing tank. A peristaltic pump located between the optical cell and the mixing tank is used for circulating the material. During the past quarter a series of shakedown test were carried out to calibrate the equipment and to determine some of its operating characteristics. The accuracy of the agitator speed and torque measuring instrument was checked. Also the gas dispersing effectiveness of the mixing system was investigated. In addition, the effects of agitator speed and solids concentration on agitator torque and power requirements were studied.
