【摘要】 氯碱工业是基本的化学工业，它的产品氯气和烧碱在国民经济中占有重要的位置。氯碱工业生产烧碱的主要原料为氯化钠，俗称原盐。而原盐又分为固体盐和液体盐。在卤水资源比较丰富的地区，氯碱生产企业提高用烧碱生产中的液体盐用量，可为社会创造效益。但提高烧碱生产中的液体盐用量，对企业而言，在经济上是否有利?理论上是否可行?实施方面是否可能呢? 本文以自贡鸿化股份公司氯碱的生产为背景，针对该企业在隔膜烧碱生产法和离子膜烧碱生产法共存的情况下、其烧碱生产中的液体盐用量比例不高的问题，开展课题研究。 首先，通过技术经济分析认为，在卤水丰富的地区，提高烧碱生产中的液体盐用量，能为氯碱生产企业带来可观的经济效益。其次，通过建立提高烧碱生产液体盐用量(提高用卤比)的数学模型及讨论，从理论上论证了提高烧碱生产中液体盐用量，乃至于实现全卤制碱是可行性的。 本文是从技术经济分析、理论上研究提高烧碱生产中的液体盐用量的可行性，同时结合该企业的生产实际情况，开展课题攻关。通过强化管理、技术革新、优化生产工艺等措施，最终解决其管理上、技术上的一些问题，实现其用卤比例的提高，增加了企业的经济效益。 该文的研究成果，能为我国同类企业的技术创新和改造提供重要的经验和指导，从而充分发挥我国卤水资源极其丰富的优势，增强我国氯碱企业的竞争力。更多还原

【Abstract】 Chlor-alkali industry is a basic chemical industry .Its products chlorine and caustic soda play significantly role in national economy. A main raw material in the chlor-alkali production is sodium chloride or salt which could be in the form of the solid and the liquid. Social benefits could be created by using more liquid salt in a richer brie area. However, whether using more the liquid salt in the production is more economic benfits to a enterprise? Is it possible in theory and feasible in implementation ?With the background of chlor-alkali production of Honghe Chemical Inc ,this paper is aimed at the problem that brine proportion is not high in the production under the co-exist of two caustic soda processes, which are diaphragm process and membrane one.Firstly, with technical and economic analysis, it found that increasing the amount of the liquid salt in the rich brine area could bring a considerable economic benefits to a enterprise. Then, the possibility of enhancing the brine proportion even using the entire brine in the soda processes was proven theoretically by establishing the mathematic models and resolving them.The paper proved the feasibility for increasing brine in the production according to the technical-economic analysis, and theoretical studies. On the basis of the above, we carried out the project, combined with the production practices of Honghe company. By the means of the strengthened management, technical innovation and improved process etc, the problems in management and technology were finally solved with enhancing the ratio of brine and better economic results to the company were achieved remarkably.The achievement of the study can provide an important experience and guidance to the technical innovation and the reform to similar other enterprises in China. Therefore, it is very important to use the advantage of rich brine source in China and to strengthen competing abilities of Chinese chlor-alkali enterprises.更多还原
