Keywords:Sodium aluminate, scaling, wide-channel plate heat exchanger, maintenance. 1. Introduction. In the alumina production, the stability of sodium aluminate solution greatly restricts its precipitation yield. Because of the controllability, cooling system has become the most effective
Jul 17, 2020 · Metallurgical industry:cooling of aluminate mother liquor heating, cooling of sodium aluminate, cooling of aluminum smelter lubricating oil. Machinery manufacturing industry:all kinds of quenching liquid cooling, cold pressing, industrial machinery lubricating oil, heating machine oil. Food industry:salt, milk, soy sauce, vinegar Exchanger - an overview ScienceDirect TopicsSodium aluminate. Sodium hydroxide. Sodium hexametaphosphate. These data collected from fouling resulting from milk pasteurisation in a plate heat exchanger, are reproduced in Table 16.18 and determining the configuration of air-cooled exchangers is the low density and poor thermal conductivity and specific heat of the cooling medium
Plate material can choose 316L, 254SMo, AL-6XN, etc. All-welded wide-channel plate heat exchangers are used in the intermediate cooling section of the decomposition process in the alumina production process, and the aluminum hydroxide slurry installed in the decomposition process is cooled. Its main applicable features are as follows:1. ALUMINA - Plate Heat Exchanger/Plate Heat Exchanger Plate heat exchanger:to heat the refined sodium aluminate solution, separated to obtain more mother liquor. Evaporator:to evaporate and condense the mother liquor generated in the whole process, which can be used to dissolve out new bauxite at high temperature and achieve the cycle collection of mother liquor.
