METHOD FOR RECOVERING ABSORPTION SOLVENT IN PROCESS FOR PREPARING BUTADIENE THROUGH OXIDATIVE DEHYDROGENATION |
摘要 |
The present invention relates to a method of recovering an absorption solvent in a butadiene production process through oxidative dehydrogenation, the method including: a) transferring a light gas discharged from an upper portion of an absorption tower to a wash column; and b) recovering the absorption solvent included in the light gas by a solvent circulating in the wash column. Since an absorption solvent may be prevented from being introduced into a reactor, or being discharged to an outside of a system, economic efficiency of a butadiene production process is improved. |
