Oil produced from Ghana cocoa bean for potential industrial
This study highlights the extraction and characterisations of oil obtained from the Ghana cocoa bean crop to evaluate its suitability for industrial applications. A
Re-refining Used Engine Oil in Ghana Using Solvent Extraction
However, used engine oil can be a valuable resource when recycled. This study investigates the recovery of base oils from used engine oils collected in one Ghanaian municipality. The used engine oils are re-refined either through acid-clay treatment or solvent extraction. Pour point, density, viscosity index, and total acid number of used

Compared to solvent extraction, acid-clay treatment was found to be less selective. When nitric acid or sulphuric acid was used, acid-clay treatment often
Effects of Different Extraction Solvents on Oil Extracted
Therefore, selection of a solvent for oil extraction is one of the most important steps in oil extraction by chemical methods . Generally, hexane is the most commonly used solvent for the extraction of oils from plant sources due to its low boiling temperature and easy recovery from the extract, and since most oils are soluble in hexane .
Green solvents and technologies for oil extraction from
Aqueous extraction involves water as a medium to extract the oil from oilseeds. It is well known that the lipid molecules are amphipathic in nature and the water soluble components diffuse into water which culminates into emulsion formation [21]. The emulsified oil in water can be de-emulsified by changing the temperature or deploying enzymes. Henc...ecolink
Green solvents and technologies for oil extraction from
The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n -hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents.
Best Solvents for Oil Extraction Oil Extracting Solvents
Safe Solvents for Oil Extraction: Acetone Acetone is a potent solvent that dissolves and extracts with ease, and it’s high evaporation rate expedites the
Base oil recovery from waste lubricant oil by polar solvent
This paper proposes a greener approach to the intensification of base oil recovery for truck engines (32,500 km of use) using ethanol, propan-2-ol, 2-methylpropan-1-ol, and butan-1-ol as solvents for the extraction of base oil, combining mechanical stirring (220 rpm) and ultrasound (25 C, 24 kHz, and 400 W). The results indicated that the recovery yields of the base oil, using the mechanical
