Capacitive Phase Shift Detection for Measuring Water Holdup in Horizontal Oil–Water Two-Phase Flow
Sensors, 2018 In this paper, a phase shift detection system of flow impedance is designed based on a concave capacitance sensor (CCS). The flow impedance of oil–water stratified flow is investigated by establishing an equivalent circuit model and a finite ...

Two-phase Taylor–Couette contactors: Holdup, axial dispersion, and droplet size
Separation Science and Technology, 2019 The simple and robust design of Taylor–Couette contactors has been attracting interests of research and industry since it was invented in the nineteenth century. Taylor–Couette contactors provide flexible operation under harsh operation conditions, as needed in liquid–liquid extraction.

Investigation of Operating Parameters’ Effects on Bubble Characteristics in a Co-Current Downflow Bubble Column [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2022 Bubble columns are frequently employed as multiphase reactors and gas-liquid contactors. In the bubble column, gas is dispersed into the liquid phase. The dispersion of gas into a liquid is the function of bubble size and its distribution.

Stage Holdup of Dispersed Phase in Disc & Doughnut Pulsed Column
Energy Procedia, 2014 AbstractSolvent extraction is one of the key unit operations in the process industries including the fuel recovery unit of nuclear power plants. Among various types of solvent extraction units, the pulsed column is emerging as one of the best choices because of its much smaller footprints compared to the most commonly used mixer-settler type extraction
