RECOVERY METHOD OF ABSORBING SOLVENT IN BUTADIENE MANUFACTURING PROCESS USING OXIDATIVE DEHYDROGENATION

摘要

The present invention relates to a method for recovering an absorbing solvent in a butadiene production process using oxidative dehydrogenation. The method comprises: a) a step where a product gas discharged from an upper portion of an absorbing tower is transferred to a wash column; and b) a step where a solvent circulating in the wash column recovers an absorbing solvent contained in the product gas. The present invention is provided to improve economical efficiency of a butadiene production process by preventing an absorbing solvent from being introduced into a reactor or being discharged to the outside of the system.
