| Abstract: | It is an improved heat filter operation by means of heating the filter liquor directly to produce steam. It has fully utilized the heat energy of vapor to keep liquor in funnel at a high temperature and to facilitate the heat filtration in a recrystalization process. It is simple and easy and has increased the recovery of recrystalization. |
