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 ...
Extension of a multi-criterion performance indicator model for post combustion CO2 capture using amine solvents.
Energy generation by carbonaceous fuel combustion has been identified as one of the predominant sources of CO2 emissions. Many scientists and researchers believe that rising CO2 levels have an adverse effect on the ...
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 ...
Activity of complex multifunctional organic compounds in common solvents.
The models used in the prediction of activity coefficients are important tools for designing major unit operations (distillation columns, liquid-liquid extractors etc). In the petrochemical and chemical industry, well ...
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 ...
Investigation of perfluorocarbons as potential physical solvents for flue gas cleaning.
Abstract available in PDF file.
Solubility studies of carbon dioxide in novel hybrid solvents using a new static synthetic apparatus.
The use of alkanolamine solutions in removing acidic gases from natural gas is common in the industry, but such technologies have disadvantages which include amongst others, solvent loss, corrosion and high heat consumption. ...
