Predispersed solvent extraction
A new solvent extraction method has been developed for the extraction of metal and organic ions from very dilute aqueous solutions. The new method, which has been named Predispersed Solvent Extraction (POSE), is based on the principle that 1 there is no need to comminute both phases. All that is …

Directional solvent extraction desalination
… desalination technology using directional solvents capable of extracting pure water from a contaminated solution without themselves dissolving in the recovered water. This method dissolves the water into a directional solvent by increasing its temperature, rejects salts and other …

Solvent extraction of phosphoric acid
… of phosphoric acid using a suitable organic solvent, followed by re-extraction of the acid from the solvent using water. The work consisted of practical batch and continuous studies and the economics and design of a full scale plant, based on the experimental data. A comprehensive literature …

Solvent extraction of lubricating oils
… balance, Viscosity Gravity Constant for each extraction and the contact area in conjunction with the material balance when a cylinder stock out of midcontinent oil was subjected to furfural refining in a one-inch in nominal diameter pyrex glass spray column using various ratios of furfural to …

Modeling Solvent Extraction of Lignin from Hardwoods
<p>This study interprets the observed behavior of solvent extraction of lignin from hardwoods by adapting the framework of the FLASHCHAIN theory (Niksa and Kerstein, 1991; Niksa, 2017). A constitution submodel specifies distributions of molecular weight and reactive sites for native lignin. The …

Solvent extraction of cobalt and nickel carboxylates
This thesis is concerned with the solvent extraction of ternary complexes of cobalt(II) and nickel(II). In a preliminary survey, the extraction of nickel(II) by a variety of systems containing carboxylic acids in the presence of 1,2-diaminoethanes was investigated in order to determine the extent …

Purification of phosphoric acid by solvent extraction
… for purifying wet-process phosphoric acid by solvent extraction should be economically viable. The work was divided into two main areas, (i) chemical and physical measurements on the three-phase system, with or without impurities; (ii) process simulation and optimization. The object was to …

Construction of prototype system for directional solvent extraction desalination
Directional solvent extraction has been demonstrated as a low temperature, membrane free desalination process. This method dissolves the water into an inexpensive, benign directional solvent, rejects the contaminants, then recovers pure water, and re-uses the solvent. In order to bring this …

Predispersed solvent extraction of copper from dilute aqueous solution
Predispersed Solvent Extraction (POSE) was used to extract copper ions from dilute acidic aqueous solution. POSE is based on the principle that there is no need to comminute both phases. All that is necessary is to comminute the solvent phase prior to contacting it with the feed. This is done by …

Advancing solvent extraction technology for improved management of contaminated liquors
The separation of minor actinides (An) such as americium and curium (Am, Cm) from lanthanides (Ln) in spent nuclear fuel can reduce the radiotoxicity of the eventual waste product as well as the required size and environmental impact of any subsequent geological disposal. In addition, separation of …

The modelling of equilibrium data for the solvent extraction of metals.
In the design of a solvent extraction plant for metals it is necessary to treat the equilibrium data either graphically or analytically. This enables stagewise calculations to be performed to explore solvent usage and feed conditions and so optimise on the cost of recovery of the metal. The present …

Solvent extraction of first-row transition metals by thiosubstituted organophosphinic acids
Organophosphorus compounds are well known as solvent-extraction reagents. Two new reagents in this class are Cyanex 302 and Cyanex 301, the respective mono- and dithio analogs of the commercial extractant, Cyanex 272 (bis(2,4,4-trimethylpentyl)-phosphinic acid). The replacement of oxygen by sulfur …
