Apparatus for distilling high boiling point liquids

... In a distillation vessel for high boiling-point liquids, the liquid space is divided by an annular partition into an inner and an outer chamber; liquid entering the inner chamber by a pipe a is heated by a steam coil c, and is kept in circulation by a steam jet w which raises it through the tube d until it is thrown back by a deflector plate z. A pipe spray g may also be used. The partially distilled liquid passes out through an aperture k into the outer chamber where it is further distilled as it progresses round from the entry k to the outlet e, separated by a partition m. Vertical guide plates n with base apertures v serve to secure an even passage of the liquid. The outlet e communicates through a valve s with the immersion pipe f, to permit re-circulation. A spray trap t3 is arranged to return liquid to the inner chamber. The annular partition q is preferably double, and may communicate with the vapour space, particularly when working under ...

Improvements in or relating to aqueous hydrolysis reactions of hydrolysable fatty materials

Fatty material is hydrolysed with water to give fatty acids and glycerine by a process in which a current of the fatty material is acted upon by a counter-current of heated water while subjected to elevated temperature and sufficient pressure to maintain water in the liquid phase, the water being heated by heat exchange with the fatty acids leaving the process and also by direct steam injection. In Fig. 1, molten fat enters autoclave 1 through line 5 while heated water enters the autoclave through distributer 2. Fatty acids leave the autoclave through tee 10 and glycerine water through line 3. Water is supplied by distributer 33 to heat exchange vessel 32, fatty acids entering vessel 32 through line 28 and leaving through line 34. The heated water leaving vessel 32 is further heated by means of steam injector 36 before passing to autoclave 1. Since vertical line 31 has water and fatty acids passing in opposite directions along it, a certain amount of fatty acid is always returned to autoclave ...

... 547,168. Distilling fatty acids. STEVENS, A. H. (Armour & Co.). Feb. 14, 1941, No. 2040. [Class 32] Higher fatty acids, e.g. palmitic acid, are recovered from stock containing them, e.g. acidulated cotton seed foots, by preheating the stock and passing it into a fractionating column where the stock is stripped of its lighter fractions by steam and then passing the stock into a heated fractionating column where the fatty acids are distilled off under reduced pressure and in the absence of steam ; the residual stock from the second column is flashed with reduction of pressure and the residues returned to the bottom of the first column for further distillation with steam. The fatty acid stock is fed from a pipe 10 through a preheater A into the upper part of a fractionating tower B supplied at the bottom with steam through line 46. The vapours and steam are withdrawn through line 14 and condenser 15 to receiver D, part being returned as reflux to tower B by pump 41 and line 42. The stripped ...

Improvements in or relating to methods of and apparatus for separating the components of a liquid system or solution

... A mixture of water, an oil, e.g. stearic or oleic acid, and a volatile organic solvent such as methanol, which is miscible with water, but does not form an azeotropic mixture with it, is separated by introducing it into a stripping column down which it flows in countercurrent to steam from a boiler at the base of the column into which the stripped water/oil mixture is conducted. The boiler is in communication with a settling receiver where the water and oil stratify, the oil layer being periodically withdrawn. The solvent vapours, which are preferably of approximately the same composition as the water/solvent component in the original mixture, are withdrawn from the top of the column and condensed. In an example, a feed mixture of 49 per cent fatty acid and 51 per cent of methanol/water solvent-consisting of 90 per cent methanol: 10 per cent water-was fed in the top section of an eight-plate bubble column 1, the stripped oil/water mixture dropping into a boiler working ...

Improvements in or relating to methods of separating mixed fatty acids

Animal fatty acids such as stearic, palmitic, and oleic are separated by chilling a solution thereof in an organic solvent to which a small amount of neutral fat has been added, whereby crystals of good filtering characteristics are formed. The neutral fat content of the stock is adjusted to from 0.2 to 3.5 per cent based on the weight of the stock. Preferably a water-miscible polar solvent such as methyl, ethyl or isopropyl alcohol, or acetone containing water not in excess of 15 per cent, is employed. If the fatty acid stock should itself contain more than 3.5 per cent of fat, fatty acid free from neutral fat is added to reduce the free fat content to the stated limits. The concentration of the fatty acids in the solvent must not substantially exceed 30 per cent by weight. This process is applicable to the fractionation of stearic and palmitic acids.
