摘　　要：氯碱化工多年发展及生产实践证实,以盐卤替代原盐生产氯碱的工艺成熟,并取得了一定的经济效益。对于盐湖发展而言上亿方卤水、上万方的洗盐,逐步应用于氯碱化工,不仅可以挖潜增效提升成本优势,对盐湖钠资源综合开发利用,助力盐湖“十四五”发展战略意义重大。The development and production practice of chlor-alkali chemical industry for many years have proved that the process of replacing raw salt with bittern to produce chlor-alkali is mature and has achieved certain economic benefits. For the development of salt lake, hundreds of millions of cubic meters of brine and tens of thousands of cubic meters of washed salt are gradually applied to chlor-alkali chemical industry, which can not only tap the potential, increase efficiency and improve the cost advantage, but also be of great significance to the comprehensive development and utilization of sodium resources in salt lakes and help the development strategy of salt lakes during the 14th Five-Year Plan.
