Filed: 1932-12-29
Abstract: <PICT:0412594/III/1> In fractionating vapours evolved from a still surmounted by a fractionating column 2 and a dephlegmator 6, the temperature of the vapours condensed in the dephlegmator 6 and returned as reflux to the top of the fractionating column is maintained substantially the same as that of the vapours emerging from the column by circulating the fluid, e.g. oil, alcohol, water &c., used as cooling medium in the dephlegmator through the tubes 20 of a condenser 19 cooled by an auxiliary fluid supplied through a pipe 32, the flow of which is controlled by a flow meter 36 in accordance with the temperature indicated by a thermometer 30. The latter may be replaced by a thermostat controlling the flowmeter 36. The circulation of the cooling fluid may be regulated by changing the height of the condenser 19 above or below the dephlegmator 6, by controlling the amount of fluid allowed to pass through the valve 42, or by inducing a forced circulation by a pump 44 placed in a byepass 46, while the surface area of the dephlegmator can be decreased by shutting a valve 56 and opening a valve 58.  The vapours escaping through the pipe 60 are condensed in a cooler 62 and collected in a receiver 68 which may be maintained under vacuum by a pump 70.  The column 2 may be filled with Raschig rings &c.  The process is particularly adapted to the fractionation of mineral oils, aliphatic and aromatic hydrocarbons, and their derivatives.

Abstract: 1358095 Separation of sulphonic acids SOC NATIONALE DES PETROLES D'AQUITAINE 6 Aug 1971 [7 Aug 1970 22 July 1971] 37075/71 Heading C2C A process for the separation of hydrocarbon sulphonic acids from a sulphonic acids solution A containing also sulphuric acid, water and possibly non-sulphonated hydrocarbons comprises adding to the solution at least one slightly polar alcohol having at least 5 carbon atoms and which is substantially unreactive towards sulphuric acid to cause separation of the solution into an organic phase B containing the sulphonic acids and an aqueous phase containing almost all of the sulphuric acid, separating the organic phase from the aqueous phase and treating the former to separate out the sulphonic acids as free acids or salts. The sulphonic acids may be separated from any unreacted hydrocarbons by treating A or B with a light polar solvent which is immiscible with the hydrocarbons and which causes separation of the hydrocarbons. When added to A the light polar solvent may be recovered therefrom by distillation after separation of the hydrocarbons. The organic phase after separation of the hydrocarbons, may be (a) treated with an alkaline or alkaline earth metal hydroxide to neutralize the sulphonic acids therein to sulphonates from which the slightly polar alcohol are separated by evaporation at a temperature and pressure at which the sulphonates are molten or (b) have water added to it to form an azeotropic mixture with the alcohol which is removed from the sulphonic acids by distillation at subatmospheric pressure. The molten sulphonate from (a) may be atomized in a current of cold inert gas to form a powder which is free flowing and anhydrous and may have a grain size between 40 to 600 Á.
