Abstract

PURPOSE: To increase the size of a titled device so as to be suited for large volume treatment while maintaining prescribed refining performance by mounting the vanes of the number on the basis of the effective sectional area of a refining tower on the same number of the spiral lines of the revolving shaft of an agitator.
CONSTITUTION: An agitator is mounted with vanes 8 of the size on the basis of the effective sectional area of a refining tower 1 on the same number of the spiral lines on the basis of the effective sectional area of the tower 1. The crystals loosened during the course of ascending in the tower 1 are subjected repeatedly and continuously to adsorption of the soln. into small crystal lumps by the melt of descending refining components, washing, dissolving and the crystallization in accordance with the purity and temp. of the crystal components of that time, whereby the raw material crystals are successively refined while ascending in the tower 1. Examples of materials that can be refined by this device are refining of crude paraxylene contg. methaxylene, orthoxylene, ethyl benzene and the like.
