Abstract

Introduction of undesirable materials through liquid containing vessels of an ether forming unit into an alkylation unit is prevented by pressurizing one or more of these liquid containing vessels of the ether forming unit with a gas which is compatible with both the ether forming reaction and the alkylation reaction and which has a boiling point to keep it in essentially the gas phase in the pressurized vessel and to keep it in the liquid or dissolved form in the overhead accumulator associated with the fractionator of the alkylation unit (if said gas is present in the accumulator at all).
