西藏捌仟措盐湖卤水等温蒸发试验研究

Experimental Research on the Isotheral Evaporation of the Brine in Baqiancuo Salt Lake

以西藏捌仟措盐湖卤水为研究对象,依据Na+,K+,Mg2+//Cl-,SO24--H2O五元水盐体系相图,对该盐湖卤水进行了5℃等温蒸发试验,研究了卤水蒸发过程中盐类析出规律和钾、锂和硼在蒸发过程中的富集行为,为该盐湖卤水盐田规划设计、现场生产操作提供了依据。

The subject of this paper is the brine in Ba Qiancuo salt lake of Tibet Plateau, according to the metastable phase of Na＋ ,K＋,Mg2＋//Cl- ,SO2- -H2 O, the isotherm evaporation of the brine is carried out at 5℃, through the experiment crystallization law of salts and the enrichment behaviour of K＋ , Li＋, B2O3 is studied. A basis for the programming as well as designing of salt fields and directing the production and operation on the spot were given.
