It is important to understand the gas–liquid mass-transfer performance for the reactor design
and scale-up of bubble columns. Air-water bubble columns have been extensively …

Mass transfer coefficient k L a determines the flux of dissolved oxygen DO in bubble
columns. The k L a values can be determined experimentally or predicted using a …

The large amount of municipal wastewater discharged into urban rivers sometimes exceeds
the rivers' self-purification capacity leading to black-odorous polluted water. Electro …

A systematic scale-up study on a rotating packed bed (RPB) reactor is essential before the
industrial application. However, the mass transfer and application performance of the RPB …

Bubble cutting was realized by installing a wire mesh in a micro-structured bubble column
(MSBC) and studied experimentally with liquid viscosity range from 1 to 39.6 mPa· s. A non …

Absorption mass transfer coefficients (kla) of methane into two widely used drilling fluids
base oils-internal olefins and diesel were determined at elevated pressure. A laboratory …

Barbotage reactors such as airlift reactors (ALR) and bubble column reactors (BCR), due to
their two-phase flow systems, were investigated in many research papers. In their basic …

In the current study, Polyimide (P84)-based polymeric membranes were fabricated and used
as spargers in the bubble column reactor (BCR) to get a high gas-liquid mass transfer (GL …

Upscaling biochemical processes from the laboratory scale to industrial scale is very
challenging as performance losses are typically observed along the scale-up process. In this …

Biomass is a promising source of energy for the future world given the carbon neutral nature
and sustainable production processes. Several processes for the conversion of biomass …
