Multipurpose separation and purification facility.
A waste acid stream is being produced by a local petrochemical company (SASOL) at a rate of 10 000 -12 000 tons per annum and contains approximately 44-mole % butyric acid, 20 % isobutyric acid and 10 % valeric acid. ...
Monoethanolamine : suitability as an extractive solvent.
Separation processes are fundamental to all chemical engineering industries. Solvent separation, either liquid-liquid extraction or extractive distillation, is a specialised segment of separation processes. Solvents can ...
Ionic liquids as solvents in separation processes.
Due to the ever increasing need for sustainable development, the chemical and allied industries have been at the focus of much change. Decreasing tolerances on pollution via waste streams has resulted in a re-examination ...
An investigation into the potential of NFM, DEG and TEG as replacement solvents for NMP in separation processes.
Optimisation attempts within the petrochemical industry have led to interest in alternate solvents. The most widely used commercial solvents for the separation of hydrocarbons, by extractive distillation, are N-methylpyrrolidone ...
The separation of hexafluoropropylene and hexafluoropropylene oxide using toluene and a novel solvent.
ABSTRACT PELCHEM, the chemical division of NECSA, produces the fluorocarbon hexafluoropropylene (HFP) onsite. In 2005 PELCHEM initiated research into the wet oxidation of HFP to produce the higher value fluorocarbon ...
The development of a three-phase filtration cell
The chemical and process industries rely largely on filtration processes to separate solid-liquid process
Modelling of a vibrating-plate extraction column.
Liquid extraction, sometimes called solvent extraction, is the separation of the constituents of a liquid solution by contact with another insoluble liquid. It belongs to the class of countercurrent diffusional separation ...
