Slurry bubble column measurements using advanced electrical capacitance volume tomography sensors

Dynamically structured fluidization: Oscillating the gas flow and other opportunities to intensify gas-solid fluidized bed operation

“…Figure 20 provides an example. Moving to larger 3D units will require the use of non-invasive tomographic systems, such as X-ray tomography [202,203], electrical capacitance tomography (ECT) [204,205] and capacitance volume tomography (ECVT) [206], or magnetic resonance imaging (MRI) [207,208],…”

Solid Particle Effects in Centi‐scale Slurry Bubble Columns

“…The fluidized solid particles heavily affect the fluid dynamics in the bubble columns (BCs) [3][4][5]. Recent investigations still tackle experimental [6,7] and numerical [8,9] approaches to characterize the gas phase dynamics in SBCs because of the solid particles influencing the coalescence and breakage behavior of bubbles. In addition, internals with other hydraulic diameters -corresponding to the ratio of the wetted perimeter and the flow cross-sectional area -than the column diameter have an impact on the fluid dynamics in BCs [10], e.g., bubble columns equipped with tube bundles [11].…”

Effect of Solid Particles on the Slurry Bubble Columns Behavior – A Review

“…Calculation of the gas hold-up by measuring the pressure drop using a manometer or a transducer along the column is widely used by different researchers although other methods are also available for this aim. For instance, Sines et al [26] studied the hold up of water, glass beads, and air in a SBCR using a novel technique called electrical capacitance volume tomography (ECVT) which has various advantages over the pressure gauge method; such as its ability to deliver non-invasive real-time direct measurements without making any assumptions about the column hydrodynamics. They concluded that their method is an acceptable method to be replaced with pressure gauge method for the study of threephase reactors hydrodynamics.…”
