摘　　要：针对生产氯化钡、硫氢化钠等产品的化工厂的困境,在不做大量投资、不做大的改动、不改变原厂的基础上,提出了改善产品结构、革新生产工艺的方法。原有生产状况是:利用原料硫化钡、盐酸、硫化钠生产氯化钡和硫氢化钠,但氯化钡亏损,整体效益差。改进新工艺为:在原有原料中增加氧化锌,即以粗质氧化锌、硫化钡、盐酸、硫化钠为原料生产氢氧化钡、氯化锌、硫氢化钠,以效益好的氢氧化钡、氯化锌取代了氯化钡,并保存了原来效益好的硫氢化钠,整体效益大大提高。In view of the difficult position of the plant of producting BaC12 and NariS, and on the basis of existing process,the improvement of the product structure is put forward. The old process is that the BaS,HlL and Na2S are used as raw material to produee BaCl2 and NariS. Due to the loss of BaCl2 production, the overall benifit of the enterprise is lower. While in the new process,the ZnO is added in the raw materials,i, e. ,the coarse ZnO,BaS,HCl and Na2S are used as raw materials to produce Ba（OH）2,ZnCl2 and NariS. Because the Ba（OH）2 and ZnCl2 ,whose benifit is better, substitute for BaCl2 , thus, the total benifit of the plant can be improvement greatly.
