Formaldehyde mass-transfer properties study
… to human health. Thus knowledge of formaldehyde mass-transfer properties is critical to efforts to reduce formaldehyde emissions and establish related standards and regulations. The primary objectives of this project include: 1) documenting and validating procedures and methods for analyzing and …

Mass transfer to reacting laminar films
… these theories are essentially concerned with transfer to stagnant pools or to deep films in plug flow. They have no<br/>terms which represent the effect of variable sub-surface velocity perpendicular to the direction of transfer. The best-known system with such velocity gradients is the thin …

Oxygen Mass-Transfer in Tower Fermenters
… and the measurement of the rate of oxygen mass—transfer in such systems using fast-response oxygen electrodes. Consideration has been given to ways of modelling the behaviour of fast-response probes and to the evaluation of mass-transfer coefficients from the results of unsteady-state …

Rapid mass transfer in binary systems
This thesis investigates the conditions for rapid mass transfer in binary stars. Previous theoretical calculations and observations of binaries imply the existence of several different timescales for mass transfer: nuclear, thermal, or dynamical. Since the mass transfer rates differ by several …

Mass transfer in bubble column contractors
Gas holdup and overall volumetric mass transfer coefficients in bubble column contactors have been investigated for water and aqueous electrolyte solutions. Two methods were used to obtain experimental data on volumetric mass transfer coefficients: the steady state oxidation technique and a …

Mass transfer in aerated vibrated beds
… minimum fluidization velocity of the particles. Mass transfer rates from solid particles coated with naphthalene to a nitrogen stream, the fluidizing gas, are determined using a gas chromatographic technique. Two kinds of coated beads of different densities are used: Master Beads and low-density …

Hydrodynamics and Mass Transfer in Bubble Columns
… key design parameters (gas hold-up, volumetric mass transfer coefficients, gas-liquid interfacial area, and their spatial distribution) for predictive scale-up of bubble columns.</p> <p>In this work, a 4-point optical probe is used to estimate local gas hold-up and bubble dynamics (specific …

Mass Transfer Characteristics of Large Oscillating Drops
The literature related to mass transfer of solute from large, oscillating drops in liquid-liquid systems has been critically reviewed. A thermostatically-controlled spray column, provided with mirrors, was used to study the hydrodynamics and mass transfer characteristics of single large oscillating …

Optimising Mass Transfer in Synthetic Porous Materials
… multi-level networks facilitate efficient mass transfer through larger pores and increase the specific surface area via smaller branching pores. Optimising these porous structures for enhanced transfer performance has attracted considerable effort. In this regard, Murray’s law has been …

Mass transfer coefficients and effective area of packing
The effective mass transfer area (a [subscript e]), liquid film mass transfer coefficient (k [subscript L]), and gas film mass transfer coefficient (k [subscript G]) of eleven structured packings and three random packings were measured consistently in a 0.428 m packed column. Absorption of CO₂ with …

Heat and mass transfer within porous building materials
… which account for both liquid and vapour transfer through porous structures, and which enable material moisture content profiles to be produced. The equations generated in this work are transient and enable the effects of moisture and thermal capacity to be considered. An experimental …
