Prediction of Dispersed Phase Holdup in Scheibel Extraction Columns by a New Correlation [PDF]
Journal of Chemical and Petroleum Engineering, 2017 In this study, the effect of operating parameters on dispersed phase holdup in liquid-liquid extraction process has been investigated. Three chemical systems (Toluene/Water, Butyl acetate/Water, and n-Butanol/Water) were utilized and holdup was ...

Detection of Water Holdup in Oil–Water Flows Using a Curved Microstrip Sensor with Resonance-Enhanced Response [PDF]
SensorsAccurate water holdup measurement in oil–water flows remains challenging due to flow-regime-dependent dielectric distributions and the limited sensitivity of conventional amplitude- or phase-based sensing features. This paper proposes a curved microstrip

Gas holdup in a reciprocating plate bioreactor: Non-Newtonian - liquid phase [PDF]
Hemijska Industrija, 2002 The gas holdup was studied in non-newtonian liquids in a gas-liquid and gas-liquid-solid reciprocating plate bioreactor. Aqueous solutions of carboxy methyl cellulose (CMC; Lucel, Lučane, Yugoslavia) of different degrees of polymerization (PP 200 and PP ...
