dissolved nitrogen predispersed solvent extraction (dnpdse) is a new method devised for improving the performance of equipment utilized in the solvent extraction (sx) method, especially for dilute solutions. in this method, for mixing the two phases, bubble dispersion of the organic phase (colloidal gas aphrons [cgas]) is used instead of its drop dispersion in the aqueous phase. through increas...

Whey contains more than half of total solids present in the original milk, which includes 20% of the proteins, most of the lactose, minerals and water soluble vitamins. In this study, selective separation of whey components by Aphron flotation (separation of ultrafine particles by micro-bubbles) has been investigated. It has been shown that it is possible to recover valuable components of w...

Colloidal Gas Aphron as a mobility control in enhanced oil recovery is becoming attractive; it is also designed to block porous media with micro-bubbles. In this paper, the effects of surfactant concentration, polymer concentration, temperature and salinity on the bubble size of the Colloidal Gas Aphron were studied. Effects of injection rates, Colloidal Gas Aphron fluid composition, heterogene...

Residues from the food industry are a problem worldwide. Alternatives have been developed in an attempted to extract compounds from fruit pomace in other to apply those as a natural component in different products. This work has the objective to produce two extracts: (1) ethanolic extract and (2) hot water extract; and characterize the chemical composition of these extracts for future applicati...

Oxidative scrubbing is used to remove H2S from gas streams. A key problem in regeneration of the absorbent is the removal of fine particles of sulphur from the suspension of the scrubbing liquid. Dispersions of ultra-fine bubbles have been called "colloidal gas aphrons" or aphrons for short. These dispersions have interesting properties and it was found that they have particular advantages in t...

Graphite ore collected from Hunan province, south China was characterized by chemical analysis, X-ray diffraction, and optical microscopy. Rougher and multi-stage flotation tests using a mechanical flotation cell and a flotation column containing an additional centrifugal force field were carried out to promote its grade and economic value. In rougher flotation, both the mechanical flotation ce...

This analysis is conducted for a theoretical examination of the fluid flow characteristics and heat transferred by nanoparticle-enhanced drilling muds flowing through pipes under various physical conditions. Here, an important type called Aphron consideration which very effective in depleted regions. The rheological are predicted Herschel-Bulkley model. driven peristaltic pumping further aided ...

The influence of conditioning on the flotation of pyrrhotite in the presence of chlorite was investigated through flotation tests, sedimentation tests, and X-ray photoelectron spectroscopy (XPS) analysis. The flotation results show that chlorite slimes dramatically impair the flotation of pyrrhotite. Sedimentation and flotation tests reveal that conditioning can effectively remove chlorite slim...
