MVR salt and CO production project discussion on energy saving reconstruction process route selection

从项目建设背景、目的、依据等方面分析了该项目建设的必要性,重点分析了达到预期目标实现全卤制碱、热法脱硝、碘富集、联产元明粉的各项工艺线路的优缺点,以及建成后的综合运行成本、对比及社会效益,分析并提出了盐硝联产项目对盐水杂质、浓缩处置的新思路。

From the aspects of the project construction background, purpose, on the basis of analyzing the necessity of project construction, the advantages and disadvantages of the process line is analyzed to achieve the desired objectives to achieve full bittern producing alkali, thermal denitration, I enrichment, cogeneration sodium sulfate, and the comprehensive operation after the completion of the cost, comparison, analysis of social benefits. In this paper, a new approach to the treatment of brine impurities and concentrate is proposed.
