[0002] Side-line alcohol removal research generally refers to the technology of removing specific components from different positions (side-lines) of a tower during the distillation process. In the production process of alkyl hydrocarbons, the side-line alcohol removal technology is usually applied to the operation of a distillation column, aiming to efficiently separate and remove alcohol by-products from the mixture; this process is particularly important because in many alkylation reactions, alcohols are both reactants and potential by-products.
