Abstract:
(EN) The present invention relates to a continuous acrylic acid manufacturing method and a manufacturing apparatus using same, wherein the manufacturing method comprises the steps of: (1) using a catalyst to partially oxidize and react a reactant including propane, oxygen, steam, and carbon dioxide, and acquiring an acrylic acid-containing mixed gas; (2) separating the acrylic acid-containing mixed gas into an acrylic acid-containing solution and a gaseous dispersion; (3) separating an acrylic acid solution from the separated acrylic acid-containing solution; and (4) recirculating the separated gaseous dispersion into the reactant.
(FR) La présente invention concerne un procédé de fabrication d'acide acrylique en continu et un appareil de fabrication l'utilisant, le procédé de fabrication comprenant les étapes consistant à : (1) utiliser un catalyseur pour oxyder partiellement et faire réagir un réactif comprenant du propane, de l'oxygène, de la vapeur et du dioxyde de carbone et obtenir un gaz mixte contenant de l'acide acrylique ; (2) séparer le gaz mixte contenant de l'acide acrylique en une solution contenant de l'acide acrylique et en une dispersion gazeuse ; (3) séparer une solution d'acide acrylique de la solution séparée contenant de l'acide acrylique ; et (4) remettre en circulation la dispersion gazeuse séparée dans le réactif.
(KO) 본 발명은 (1) 프로판, 산소, 수증기 및 이산화탄소를 포함하는 반응물을 촉매를 사용하여 부분산화 반응시켜, 아크릴산 함유 혼합가스를 수득하는 단계; (2) 상기 아크릴산 함유 혼합가스를 아크릴산 함유 용액 및 기상부산물로 분리하는 단계; (3) 상기 분리된 아크릴산 함유 용액에서 아크릴산 용액을 분리하는 단계; 및 (4) 상기 분리된 기상부산물을 상기 반응물로 재순환시키는 단계;를 포함하는 연속식 아크릴산 제조방법 및 이를 이용한 제조장치에 관한 것이다.
