Abstract: The article makes us acquanted with the fact that the tanks either abroad or imported are all provided with agitators, which are obviously effective n preventing settlement, getting a quick blending of products and improving the heat exchanging condations. Taking the oil product agitating only to make blending as an example, it proves that the agitator is superior over the conservative way in quality, energy consumption, safety, simplized operation, maintenance and economic efficiency. Therefore, the agllator i -uggested to be broadly used as early as possible in the units conrerned.
