Title (EN) METHOD FOR PREPARING ETHYLENE IN PROPYLENE PREPARATION PROCESS USING PROPANE DEHYDROGENATION REACTION
(FR) PROCÉDÉ POUR LA PRÉPARATION D'ÉTHYLÈNE DANS UN PROCÉDÉ DE PRÉPARATION DE PROPYLÈNE À L'AIDE D'UNE RÉACTION DE DÉSHYDROGÉNATION DE PROPANE
(KO) 프로판 탈수소 반응을 이용한 프로필렌 제조 공정 내 에틸렌 제조방법
Abstract: front page image
(EN)The present invention relates to a method for producing ethylene by separately collecting ethane and ethylene, which are by-products of a propylene preparation process using a propane dehydrogenation reaction, and by combining a process for converting ethane to ethylene with a conventional process for preparing propylene. According to the present invention, economic feasibility of the process can be improved since ethane and ethylene, which are by-products of a propane dehydrogenation process, are not used as cheap fuel and are mostly converted into ethylene so as to produce expensive ethylene. In addition, the production rate of an advantageous product line can be increased since the operation condition of a propane dehydrogenation reactor and the operation condition of a de-ethanizer can be controlled according to market conditions by dividing the process product line of a propane dehydrogenation reaction from a propylene single product into propylene and ethylene.
(FR)La présente invention concerne un procédé de production d'éthylène par collecte séparée d'éthane et d'éthylène, qui sont des sous-produits d'un procédé de préparation de propylène à l'aide d'une réaction de déshydrogénation de propane, et par combinaison d'un procédé de conversion d'éthane en éthylène avec un procédé classique de préparation de propylène. Selon la présente invention, la faisabilité économique du procédé peut être améliorée étant donné que l'éthane et l'éthylène, qui sont des sous-produits d'un procédé de déshydrogénation de propane, ne sont pas utilisés comme combustible bon marché et sont principalement convertis en éthylène de manière à produire de l'éthylène onéreux. De plus, le taux de production d'une ligne de produit avantageuse peut être augmenté étant donné que l'état de fonctionnement d'un réacteur de déshydrogénation de propane et la condition de fonctionnement d'un déséthaniseur peut être commandé selon des conditions de marché par division de la ligne de produit de traitement d'une réaction de déshydrogénation de propane à partir d'un produit unique de propylène en propylène et éthylène.
(KO)본 발명은 프로판 탈수소 반응을 통한 프로필렌 제조 공정의 부산물인 에탄 및 에틸렌을 별도로 수집하고, 기존의 프로필렌 제조 공정에 에탄을 에틸렌으로 전환시키는 공정을 접목하여 에틸렌을 생산하는 방법에 관한 것으로, 본 발명에 의하면 프로판 탈수소 공정 부산물인 에탄 및 에틸렌을 저가의 연료로 사용하지 않고 대부분 에틸렌으로 전환시켜 고가의 에틸렌을 생산함으로써 공정 경제성을 향상시킬 수 있다. 또한, 프로판 탈수소 반응의 공정 제품군을 프로필렌 단독 제품에서 프로필렌과 에틸렌으로 이원화하여 시장 상황에 따라 프로필렌 탈수소화 반응기의 운전 조건과 탈에탄 탑 운전 조건을 조정할 수 있어 유리한 제품군의 생산 비율을 늘릴 수 있다.
