Patent GB-621158-A (GB)
Title: Improvements in or relating to the production of sulphuric acid or oleum
IPC: C01B17/765
Filed: 1946-10-09
Abstract: In the contact process for the production of sulphuric acid or oleum, molten sulphur is converted into an exit gas containing 14 per cent of sulphur dioxide at or below 1000 DEG  C. by passing the required relative quantities of a mixture of air and cooled fraction of the exit gas over the molten sulphur, the main stream of the exit gas being cooled to a temperature suitable for commencing its catalytic conversion and passed into a converter containing a catalyst for conversion of sulphur dioxide into sulphur trioxide, and there admixed with such a quantity of cold air that the temperature distribution throughout the converter is maintained at the optimum temperature for the conversion.  The sulphur may be burned with such a quantity of air preheated to 350 DEG  C. as would give, in the absence of the cooled exit gas with which it is diluted, a gas containing 14 per cent sulphur dioxide, which may then be passed to a waste heat boiler from which a fraction may be passed through an economiser by means of a hot gas fan to raise its temperature to 350 DEG  C. and returned to the sulphur burner.

Patent GB-308210-A (GB)
Abstract: 308,210. Consortium fur Elektrochemische Industrie Ges. March 19, 1928, [Convention date]. Acetic acid is extracted from its aqueous solutions by cooling to a temperature below -20‹ C. in presence of a solvent preferably consisting of or containing a chlorinated hydrocarbon. Solvents mentioned are dichlorethylene, trichlorethylene, methylene chloride, tetrachlorethane, esters such as acetic acid esters, acetone oil, and mixtures such as ethyl acetate and a hydrocarbon or a chlorinated hydrocarbon. In an example, acetic acid of 40 per cent is mixed with dichlorethylene while cooling to -27‹ C. until no more ice separates. The ice is separated in a centrifuge, filter press, &c. and washed with cooled dichlorethylene, the ice and cold extract being used for precooling the next portion of acetic acid and solvent or for cooling the condenser of a freezing machine. The acetic acid is recovered from the extract by distillation. To avoid the separation of ice on the cooling surfaces, the solvent is preferably cooled to -27‹ C. and then mixed, with stirring, with precooled acetic acid. Solvent from a vessel g is run into a vessel a provided with a cooling-jacket and stirrer. and is circulated by a pump b through a cooler c until its temperature is below -26‹ C. While maintaining this temperature, dilute acetic acid is run in from a vessel f, and the liquor is made to circulate through the cooler c and a centrifugal d. The separated liquid flows through a heatexchanger c where it cools the distilled solvent, and then into a fractionating apparatus i.
