Title (EN) METHOD FOR COLLECTING HARD OLEFIN
(FR) PROCÉDÉ POUR RÉCUPÉRER DES OLÉFINES RIGIDES
(KO) 경질 올레핀의 회수방법
Abstract:
(EN) The present invention relates to a method for collecting a hard olefin, the method being capable of: achieving the increase in production of propylene and the improvement of processing unit requirement through the input of steam into a 5-stage serially connected dehydrogenation reactor; and improving economic feasibility and selectivity by separately collecting ethane and ethylene, which are byproducts of a propylene preparation process, followed by conversion into ethylene, and thus dualizing a process product group of a propane dehydrogenation reaction from a propylene sole product into propylene and ethylene.
(FR) La présente invention concerne un procédé pour récupérer des oléfines rigides, le procédé permettant : d’obtenir une augmentation de la production de propylène et l’amélioration du besoin en unité de traitement par l’entrée de vapeur dans un réacteur de déshydrogénation à liaison série de 5 étages ; et d’améliorer la faisabilité économique et la sélectivité par la récupération séparée d’éthane et d’éthylène qui sont des produits secondaires d’un processus de préparation de propylène, suivie de la conversion en éthylène, et ainsi de dualiser un groupe de produits de traitement d’une réaction de déshydrogénation de propane à partir d’un unique produit de propylène, en propylène et éthylène.
(KO) 본 발명은 5단 직렬연결된 탈수소화 반응기에 스팀 투입을 통하여 프로필렌 생산량 증가와 공정 원단위를 개선할 수 있고, 프로필렌 제조 공정의 부산물인 에탄 및 에틸렌을 별도로 수집하여 에틸렌으로 전환시킴으로써, 프로판 탈수소 반응의 공정 제품군을 프로필렌 단독 제품에서 프로필렌과 에틸렌으로 이원화하여 공정 경제성 및 선택성을 향상시킬 수 있는 경질 올레핀의 회수방법에 관한 것이다.
