Patent GB-763235-A (GB)
Title: Process for dehydrating crude aqueous acetic acid by ageotropic distillation
IPC: C07C51/48
Filed: 1953-02-02
Abstract: In a process for the azeotropic dehydration of aqueous acetic acid containing methyl acetate and other low-boiling impurities by distilling it in the presence of a water-immiscible organic auxiliary liquid (i.e. water-entrainer) whereby there is obtained a distillate which separates into a water-rich layer and an entrainer-rich layer the latter being returned in part to the column, and the pure anhydrous acid is obtained at the base of the column, part of the entrainer-rich layer is withdrawn from the distillate-separator and is washed with dilute aqueous acetic acid (less than 50 per cent HAc) in order to remove the low boiling impurities derived from the crude feed acid, and the washed entrainer is then re-used in the distillation.  The water-rich layer separated from the distillate contains some acetic acid and may be used, if necessary after addition of further acid, for washing the entrainer.  The process is applicable to the dehydration and purification of crude acetic acid obtained from carbide, which acid contains methyl acetate, methyl formate, formic acid, formaldehyde and acetaldehyde, as impurities. Crude acetic acid (100 litres) and benzene (4 litres) are introduced about three-quarters the way up a column (height 4.5 metres) which is attached at the base to a heated still.  The temperature half-way up the column is maintained at 116 DEG C.  By means of a dephthlegmator the vapours leaving the column are maintained at 70 DEG C., and there is adequate reflux.  The vapours are condensed, and the condensate is passed to a separator.  About 4.5 litres of the benzene layer are withdrawn per hour, and the remainder is returned to the column. Purified acetic acid (freezing point 16.5 DEG C.) is withdrawn from the still.  The aqueous layer contains about 30 per cent of acetic acid and about 7 per cent of methyl acetate.  The withdrawn benzene, which contains about 12 per cent of methyl acetate, is extracted in a tower with five times its volume 30 per cent acetic acid, use being made of the aqueous layer of the distillate.  The benzene withdrawn from the tower has a methyl acetate content of 4 per cent, and this partially-purified benzene is returned to the distillation system.

[Class 110 (iii)] The plant comprises a steam turbine and a diesel engine and both are in operation during normal conditions. The diesel engine may assist in driving the propeller or may be used solely for the ships auxiliaries. The jacket heat and exhaust heat of the diesel engine are used for feed water heating. To secure the best economy having regard to the relative costs of diesel oil and fuel oil in different parts of the world, the power of the diesel engine lies between ten and forty per cent. of the total power of the plant. The turbine condensate is circulated, in turn, through the low temperature half of a diesel exhaust heat exchanger, the diesel jackets and the high temperature half of the exhaust heat exchanger and is returned to the boiler feed-water pump. It may also be passed through an oil cooler. The flow through the jackets may be divided so that water in addition to the condensate may be used and the heated additional water may be used to generate steam. The residual exhaust heat may be used to generate steam admitted to a late stage in the turbine and the exhaust gases may be used to produce forced or induced draught either by driving a turbine blower or by jet action. In one arrangement of plant, the turbine has two shafts carrying pinons gearing with the upper part of a main wheel on the propeller shaft and two diesel engines carry pinions gearing with the same wheel at opposite ends of a horizontal diameter.

Patent GB-879559-A (GB)
Title: Improvements in or relating to the preservation of fish
IPC: A23B4/06
Filed: 1959-01-28
Abstract: In the preservation of fresh fish, the fish are de-gasified and de-aerated by the application of a high vacuum, such that the fish cool down to about freezing temperature due to the evaporation of moisture either originally present on their surface or added during the cooling but are not frozen, and during storage the fish are kept cool and are subjected, by means of an oxygen-free medium having no deleterious effect on the fish, to a pressure higher than that prevailing under the high vacuum.  The absolute pressure under the high vacuum may be less than 4 mm. Hg and during storage greater than 80 mm. Hg.  Specified oxygen-free media are a gas, a refrigerant vapour and a liquid e.g. degasified and sterilized water.  Gas or refrigerant vapour, when employed, may not only serve to increase the pressure, but also to remove heat entering the chamber in which the fish is placed, gas or vapour being sucked out of the chamber, compressed, cooled, allowed to expand or liquefied and sprayed (as the case may be) into the chamber, sucked out again and the cycle repeated continually.  Herrings may thus be preserved for about three weeks in an unobjectionable condition at a pressure of 100 mm. Hg using difluorodichloromethane.  After being de-gasified, de-aerated and cooled, the fish can be deep-frozen by flooding the fish with refrigerant liquid in a tank and sucking out vapour from above the level of the liquid at a pressure corresponding to a certain decrease in temperature until only vapour remains in the tank the vapour drawn off is compressed, liquefied and collected in another vessel.  When the appropriate pressure has been reached in the tank, the compressor is stopped and the liquid collected is returned to the tank so as again to flood the fish.  On completion of the deep-freezing, the vapours of the refrigerant are sucked off as far as possible, for instance until a pressure of 1-2 mm. Hg has been reached, which corresponds to a temperature of -20 DEG  C. It is stated to be of decisive importance that the temperature drop from 0 DEG  C. to -4 DEG  C. be completed within 2 to 4 hours to avoid the formation of large ice crystals.  According to an example, the pressure in a tank containing herrings which had been de-gasified, de-aerated and cooled to about 1 DEG  C. under high vacuum, was raised to a pressure of 300 mm. for storage by introduction of nitrogen.  The nitrogen supply was then cut off, the gas in the tank was sucked out, compressed to a pressure of 3 kg/cm.2, cooled in a heat exchanger and expanded back into the tank by means of a nozzle, whereby the gas cooled down to about -60 DEG  C.; to avoid uneven flow of gas during re-cycling, the expansion of the gas was carried out intermittently in such a way that pressure fluctuations between 3 and 300 mm. Hg occurred in the tank.  Specification 821,369 is referred to.

Title: Manufacture of nitriles of resin acids
IPC: C07C255/45
Filed: 1933-02-02
Abstract: Nitriles of resin acids are made by causing gaseous ammonia to act on a resin acid or an ester thereof, in the presence or absence of a solvent or a diluent, at a raised temperature in the presence of a dehydrating catalyst such as aluminium oxide, thorium oxide or silica gel.  As resin acids there may be used abietic acid, colophony, mixtures of natural resin acids or esters thereof and as diluents hydrocarbons, alcohols, organic acids or nitriles such as those of resin acids or stearic acid.  In examples, (1) a mixture of benzene and colophony or root resin and heated ammonia gas is passed over silica gel, the resulting vapours being condensed and fractionated to obtain the nitrile. The resin acid may be regenerated by saponification or the amine prepared by hydrogenation by means of sodium and alcohol or by a catalytic process.  If oleic or acetic acids are used as diluents they are converted into nitriles; (2) a solution of colophony in alcohol and ammonia is passed over silica gel or glassy aluminium oxide; (4) molten American colophony or the liquid resin obtained as a waste product in the manufacture of cellulose from pinewood and ammonia are passed over silica gel in an iron tube.
