    Abstract

    The effectiveness of the slug flow in a narrow channel for the extraction of phenol from dodecane to water was studied. Extraction based on slug flow and was compared from the viewpoint of the total operation time for extraction and separation of the two phases. The enhanced circulation flow in slugs by increasing flow rate allowed rapid extraction. Large slug length compared with emulsion diameter enabled instant separation of the two phases after the extraction. Required time for extraction based on emulsion was shorter than based on slug flow. However, it took more than a few hours to separate the two phases due to the ∼ 50 μm emulsion size. Thus, the extraction based on slug flow was more preferable than based on emulsion from the viewpoint of the total operation time for the entire extraction process. Appropriate operating condition enhanced extraction efficiency in slug flow. This is an abstract of a paper presented at the AIChE Spring National Meeting (Houston, TX 4/22-27/2007).
