Patent GB-607064-A (GB)
Title: Improvements relating to the production of fatty acids and fatty alcohols
IPC: C11C3/12
Filed: 1946-01-24
Abstract: An apparatus which is suitable either for the catalytic hydrogenation of fats, fatty oils or fatty acids to produce alcohols or for the hydrolysis of fats or fatty oils to produce fatty acids and glycerine comprises (i) a heat exchanger for preheating the fatty material; (ii) a reaction vessel in which the hydrogenation or hydrolysis takes place; (iii) a separator vessel in which waste hydrogen is separated or water is flashed off, and (iv) suitable branch and byepass ducts and associated control means for enabling either of the processes to be carried out. When using the apparatus of <PICT:0607064/III/1> <PICT:0607064/III/2> Fig. 1 for the hydrogenation reaction, the fatty starting material is introduced via lines 7a and 7 to the injector 2, where it is mixed with hydrogen entering via line 8.  The mixture passes through heat exchanger 3 to the reaction vessel 4 containing removable catalyst carriers 5 and then through line 13 to the other side of heat exchanger 3.  From there it passes through line 16 to separator 6, waste hydrogen leaving through line 19 and other reaction products leaving through line 24.  When using the apparatus for hydrolysis, the fatty starting material is introduced via line 7b.  Steam enters the heat exchanger 3 through line 25 and steam condensate from the heat exchanger passes to reaction vessel 4, from which the catalyst carriers have been removed, via lines 14 and 27. Reaction products pass directly from reaction vessel 4 to separator 6, water flashing off through line 29, fatty acids leaving through line 31 and glycerine water leaving through line 33.  When using the apparatus of Fig. 3 for the hydrogenation reaction, the reaction products from reaction vessel 4 do not go to the heat exchanger but pass through valve 37 to condenser 38 and the uncondensed portion is then led to separator 6 through line 40.  The heat exchanger is heated by a fluid such as steam, any condensate passing to steam trap 44.  The condensate passes through line 27 to the reaction vessel 4 during the hydrolysis reaction as in the case of Fig. 1.  Instead of employing catalyst carriers 5, the catalyst may be introduced into the reaction vessel in powder form and recovered from the reaction products.

After a thermoplastic bag blank has been folded into tubular form on an auxiliary mandrel 1 (Fig 1) and sealed longitudinally by jaws 3, 4, it is carried by the jaws to an intermediate mandrel 6 which is rotated about its axis to re-orientate the partially formed bag prior to its transfer to a shaping mandrel 9. In the form shown a folding box 2 is raised so that the sides of the box blank are folded about the mandrel. A guide bar, which is raised before the longitudinal seam is formed, may form a guide for lining up the edges of the sheet correctly. Alternatively, compressed air may be blown through orifices in the top of the mandrel 1. A shaft 5 (Fig. 1) carrying the jaws 3, 4, is then moved towards the intermediate mandrel 6 which is preferably tapered to facilitate drawing the tube over the mandrel. The mandrel 6 is then rotated through 90 degrees so that, when the tubular blank is drawn by grippers 7 on to the shaping mandrel 9, the longitudinal seam lies along one of the side edges of the mandrel. The shaping mandrels 9, which preferably comprise two parts 38, 39 which can be moved together as the bag is drawn on to the mandrel, are carried on an intermittently rotating wheel 8.
