Apparatus and method for preparing alcohol from olefin

Abstract

Disclosed are an apparatus and method for preparing alcohol from olefin. A reactor for hydroformylating olefin comprises a loop reactor for reducing high-boiling point components, a post-treatment device for separating aldehyde comprises a catalyst/aldehyde separator and a divided wall column (DWC) for removing remaining high-boiling point components, and a post-treatment device for separating alcohol comprises a divided wall column (DWC) for removing remaining high-boiling point components. The apparatus and method for preparing alcohol reduce production of high-boiling point components in the preparation of alcohols and efficiently remove remaining high-boiling point components, thus obtaining alcohol containing no high-boiling point components.
