Abstract

Wool-grease or other fatty matter and soap or synthetic detergents having a like effect, are recovered from wool-scourers' liquors or similar trade wastes, by agitating the liquors in the presence of a solvent composed at least partly of a polar compound or compounds and which is at least partially immiscible with water and is capable of dissolving the grease or fatty matter and soap or synthetic detergent having a like effect. The solvents specified comprise fusel oil, amyl alcohols, normal- or iso-butyl <PICT:0617250/III/1> alcohol, or cyclohexanol. The soap &c. may then be recovered from the extract solution by washing with water, with or without addition of another substance such as a petroleum fraction to decrease the solubility of the soap &c. The soap &c. and the fatty matter are finally obtained from the aqueous solution and the remaining extract solution by removal of solvent respectively. The liquor separated from the first extract solution is regenerated scourers' liquor and may be re-used. In a suitable plant applied to wool scourers' liquors, the liquor is passed through a screen 2 and a sand-settling tank 3, to a mixing tank 8 for optional treatment with a small proportion of fusel oil or butanol to break the emulsions prior to the main solvent extraction preferably by counter-current in a column 12. The fusel oil or butanol in the latter are preferably used in the proportion of at least two parts by volume to one of the aqueous liquid, the column being preferably at 55 DEG C. The raffinate flows to a continuous still 15 for solvent stripping to recover regenerated scourers' liquor which may be further purified if desired. The extract solution flows to a second extraction column 21 for washing with warm water, the latter preferably containing small proportions of NaOH and an alkaline buffering agent such as trisodium phosphate. The raffinate flows to a still 27 for solvent stripping to recover the soap &c. solution, and the remaining extract solution flows to a continuous still 31 for solvent stripping to recover the crude wool-grease. In a modification of the working of the process, the optional breaking treatment is carried out in the mixing tank 8, with or without an agglutinating re-agent such as bentonite, and the clear regenerated scourers' liquor separated from the sludge and scum, which latter alone passes to the main solvent extraction stage.
