Title (EN) METHOD FOR PRODUCING BUTADIENE
(FR) PROCÉDÉ DE PRODUCTION DE BUTADIÈNE
(KO) 부타디엔 제조방법
Abstract:
(EN) The present invention relates to a method for producing butadiene and an apparatus for producing the same. According to the present invention, a C4 mixture and a gas product can be easily separated by cooling and condensation by using butane as a diluent gas, thereby having an effect of providing a method for producing butadiene and an apparatus for producing the same which can secure economic efficiency of a process such as reduction of energy and raw material costs and improvement of productivity, and high purity butadiene
(FR) La présente invention porte sur un procédé de production de butadiène et un appareil pour produire celui-ci. Selon la présente invention, un mélange de C4 et un produit gazeux peuvent être facilement séparés par refroidissement et condensation en utilisant du butane en tant que gaz diluant, ce qui a pour effet de fournir un procédé de production de butadiène et un appareil pour produire celui-ci, qui peut garantir au procédé un rendement économique, tel qu'une économie d'énergie et de coûts de matière première, ainsi qu'une amélioration de la productivité et une haute pureté de butadiène.
(KO) 본 발명은 부타디엔의 제조방법 및 제조장치에 관한 것으로, 본 발명에 따르면, 희석기체로 부탄을 사용하여, 냉각 및 응축에 의해 C4 혼합물 및 가스 생성물을 용이하게 분리할 수 있게 되어, 에너지 및 원료비 절감, 생산성의 향상 등 공정의 경제성과 고순도의 부타디엔을 확보 할 수 있는 부타디엔의 제조방법 및 제조장치를 제공하는 효과가 있다.〔대표도〕도 2
