Abstract

Experimental investigation is carried out to seek an efficient method of enhancing the agitation efficiency in the refining processes agitated by side gas injection. The use of the deep-water type of swirl motion is expected to be promising. The occurrence condition of the deep-water type of swirl motion therefore is determined by visual inspection. Mixing time is measured with an electrical conductivity sensor in the presence and absence of the swirl motion. Empirical equations are proposed for predicting the occurrence condition. The mixing time is found to be independent of the swirl motion under the conditions considered in this study.
