Abstract (en)
[origin: WO2020126374A1] The invention concerns a method for treating an alcohol feedstock comprising: a) a step of preheating the alcohol feedstock to a temperature of between 70°C and 200°C; b) a step of pretreatment on an acidic solid, carried out at a temperature of between 70°C and 200°C, in order to produce a pretreated alcohol feedstock; c) a step of partial vaporisation in order to produce a vaporised stream and a liquid stream; and d) a step of purifying the liquid stream from step c), into a stream rich in water, a stream rich in mono-alcohol and a stream rich in impurities.
