PENGARUH HAMBATAN DOWNSTREAM TERHADAP KARAKTERISTIK PEMISAHAN FASE KEROSENE-AIR PADA T-JUNCTION 90 DERAJAT
Abstract: Research on
T-Junction as a separator of liquid-liquid flow is still of interest and
developing. Some works evaluated certain geometries to obtain the best
separation efficiency. The work to examine the separation
behavior/characteristic of kerosene-water flow in a T-Junction at ratio of
elbow radius to inlet diameter horizontal pipe (r/Dh) = 0.69 carried out is
completed. The orientation of side arm is vertically right upward whilst the
ratio at diameter of the flex glass tube is set at 0.7 (horizontal tube and
vertical tube at 36 mm and 26 mms respectively). To lead kerosene to the side
arm, the downstream valve set at 75% and 50% respectively. Downstream pressure,
pressures difference at inlet-run arm (∆P1-2) and inlet-side arm (∆P1-3) and
debit of kerosene and water in side and run arm are the variable at the
research. Based on visualization and measurement at maximum flow separation
efficiency at 88%, is gained at downstream pressure 104326 Pa, watercut 46%,
Jmix = 0,31 m/s (Jw = 0,14 m/s and Jk = 0,17 m/s). The best separation result with Fk = 0,96 and Fw = 0,22 is gained
at downstream pressure 104287 Pa,
watercut 70%, Jmix = 0,56 m/s (Jw = 0,39 m/s and Jk = 0,17 m/s) and flow pattern at Stratified Bubble
Interface (ST-BI)
