Abstract
Methyl-tert-alkyl ethers coming from a synthesis section are separated from unreacted hydrocarbons by means of a rectification operation, in which the unreacted hydrocarbons are drawn as overhead fraction, in the form of an azeotropic mixture with methanol. To the purpose of removing methanol, and of therefore allowing a suitable use of said unreacted hydrocarbons, the azeotropic mixture is washed with water inside a washing column, which gets very rapidly corroded. The invention solves the corrosion problem by resorting to the removal of oxygen from the hydrocarbon charge and/or of methanol, before these are sent to the synthesis.
