ABSTRACT

ABSTRACT: The evaluations of an air separator for processing chemical engineering particulate gas streams was carried out with a view to investigate the performance for different flow rates and other characteristics. A louver (LV) air separator was used as a case study. The evaluations indicated that for various set points of characteristics, the prediction of operating efficiencies could be made for different variations of louver gap (LVG) with area ratio (AR), length of separator at particular angles of LV inclination and the number of LV with flow rates. It was observed that efficiencies ranging from 40 to 60%, on one hand, were obtained for high values of LVG and gas flow rate. On the other hand, efficiencies of 61 to 99% were obtained for lower values of LVG and gas flow rate. It was noted therefore that in order to produce high efficiencies, the values of LVG and flow rates have to be low and vice versa. The evaluation indicates also that plant operators can quickly predict, from the results, the operating efficiency for the desired dimensions and or flow rates of particulate gas streams. The methodology for the determination of operating data can be used in minimum-time frame to optimize the operations of the plant.
