DISPLACEMENT DESORPTION PROCESS FOR LIGHT OLEFIN SEPARATION
摘要
<p>PURPOSE: Substitution-desorption process for light olefin separation is provide to collect olefin in gas exhausted from an olefin cleansing step by introducing a recovery step before or after an adsorption step, thereby securing olefin collecting ratio higher than existing processes. CONSTITUTION: Substitution-desorption process for light olefin separation from olefin-containing mixed gas comprises: a step of adsorption olefin by introducing olefin-containing mixed gas into an adsorption bed; a step of collecting olefin by introducing olefin-containing gas exhausted from an olefin cleansing step to the adsorption bed; a step of increasing the purity of olefin in the adsorption bed with cleansing paraffin and other gases by introducing olefin of high concentration into the adsorption bed; and a step of manufacturing olefin of high purity by desorbing olefin by introducing desorbing agent to the adsorption bed.</p>
