Technical Reforms on Megaton Industrial Salt Production Line in Keke Salt Lake

盐是化学工业之母,化学工业是国民经济的基础产业,三酸(硫酸、盐酸、硝酸),两碱(纯碱、烧碱)是基本的化学工业,而其中的盐酸、纯碱、烧碱是以盐为主要原料生产的,每生产1 t纯碱或烧碱要消耗1.2 t～1.4 t的盐,全世界用于生产钠碱、氯和氯的衍生物等80多种基本化工产品所用的盐,占全世界总盐耗量的60%以上,在工业发达的国家,化工用盐一般都占到总盐耗量的90%以上,因此可以说,国民经济的全面发展,依赖于发达的化学工业,而发达的化学工业又依赖于发达的制盐工业。

Salt is the mother of chemical industry. And the chemical industry is the basic in- dustry in the nation. The three kinds of acid （sulphuric acid, hydrochloride acid and nitric acid） and two kinds of alkali（ sodium carbonate, sodium hudroxide） are the basic chemical product. Salt is the raw material to produce hydrochloride acid, sodium carbonate and sodium hudroxide. 1.2t to 1.4t of salt is consumed to produce It of sodium carbonate. Over 60% of total salt in the world is consumed to produce sodium alkali, chlorine, chlorine derivant and other over 80 kinds of chemical product. In developed countries, over 90% of total salt is used in chemical industry. So, it de- pends on advanced chemical industry to develop national economy with all sides. However, the ad- vanced chemical industry depends on the advanced salt industry.
