Abstract:
(EN) The purpose of the present invention is to provide a separation method by which a light liquid and a heavy liquid can be efficiently separated from a mixed liquid containing a light liquid, a heavy liquid, and an emulsion of the light liquid and the heavy liquid, such as an extracted liquid from an emulsified layer in vicinity of an interface in an extraction column. The present invention relates to a separation method for continuously introducing, into a separation tank, a mixed liquid containing a light liquid, a heavy liquid having a specific gravity larger than that of the light liquid, and an emulsion of the light liquid and the heavy liquid and continuously separating the light liquid and the heavy liquid from the mixed liquid, wherein a specific separation layer is used for the separation tank.
(FR) Le but de la présente invention est de fournir un procédé de séparation par lequel un liquide léger et un liquide lourd peuvent être efficacement séparés d'un liquide mélangé contenant un liquide léger, un liquide lourd, et une émulsion du liquide léger et du liquide lourd, tel qu'un liquide extrait à partir d'une couche émulsifiée au voisinage d'une interface dans une colonne d'extraction. La présente invention concerne un procédé de séparation pour introduire en continu, dans un réservoir de séparation, un liquide mélangé contenant un liquide léger, un liquide lourd ayant une densité spécifique supérieure à celle du liquide léger, et une émulsion du liquide léger et du liquide lourd et de séparer en continu le liquide léger et le liquide lourd du liquide mélangé, une couche de séparation spécifique étant utilisée pour le réservoir de séparation.
(JA) 本発明は、抽出塔内の界面近傍の乳化層抜き出し液のような、軽液、重液及び該軽液と該重液との乳化液を含有する混合液から軽液と重液を効率的に分離できる分離方法の提供を目的とする。本発明は、軽液、該軽液より比重が大きい重液及び該軽液と該重液との乳化液を含有する混合液を連続的に分離槽に導入して該混合液から該軽液と該重液とを連続的に分離する方法であって、該分離槽として、特定の分離層を用いる分離方法に関する。
