Characterization of airborne particles and droplets: Relation to amount of airborne dust and dust collection efficiency
(Wiley-VCH Verlag, 2002-03)
Water sprays have been commonly used to suppress airborne dust. Water is doped with surface-active agents to enhance the dust capture efficiency through a reduction of surface tension. Nevertheless, dust collection ...
Physical and chemical interactions in coal flotation
Coal flotation is a complex process involving several phases (particles, oil droplets and air bubbles). These phases simultaneously interact with each other and with other species such as the molecules of a promoting reagent ...
Adsorption of PEO/PPO triblock co-polymers and wetting of coal
The adsorption characteristics of PEO/PPO/PEO triblock co-polymers on coal were investigated using surface tension and contact angle measurements. Although these surfactants have been widely used as wetting agents, it was ...
Kinetics of oil dispersion in the absence and presence of block copolymers
(American Institute of Chemical Engineers, 1999-09)
A phenomenological model proposed describes droplet breakup in the turbitlently agitated lean oil-in-water dispersions and provides a correlation between the median droplet size in an agitated vessel of standard geometry ...
Electrostatic charge on spray droplets of aqueous surfactant solutions
Electrostatic charges on individual spray droplets were measured using a refined form of the Millikan oil drop method. The measurement system consisted of three main sections; a droplet generation cell, a settling column ...
