<p> The separation of a mixture of carbon tetrachloride in water was studied in a 2 inch diameter glass hydrocyclone. First, the effect of a mixing valve and of oil/water ratio on the volume/surface diameter of the dispersion in the feed to the hydrocyclone was studied using a statistical experiment design. Secondly, the effect of feed drop size distribution, oil/water ratio, and overflow/underflow split on the separation in the hydrocyclone was determined, again using a statistical experiment design. In both designs, five levels of each variable were studied. Flow rate, design shape, and temperature were kept constant. The range of variables was: </p> <p> 1. Mixing Value Pressure Drop 17.95 to 88.25 mm. Hg </p> <p> 2. Oil/Water Ratio 0.132 to 0.211 </p> <p> 3. Overflow/Underflow Split 4/1 to 8/1 </p> <p> From the first part of the work it was found that oil/water ratio had no significant effect on the volume/surface diameter, and that there was a linear relationship between the volume/surface diameter and mixing valve pressure drop. </p> <p> From the second part of the work it was found that volume split had most significant effect on hydrocyclone separation for the range of variables studied. The oil/water ratio had the next most significant effect on separation, and finally, drop size distribution was also found to be significant, but was the least important of the three variables. The interactions of the variables were no significant. The hydrocyclone separation could be predicted. The prediction of the overflow drop-size distribution agreed very well with the distribution observed photographically. Both predictions required assumptions that short-circuit flow and drop-drop coalescence was negligible. </p> / Thesis / Master of Engineering (ME)
