摘要
对国外先进的水合肼生产工艺——拜尔工艺和ｐｃｕｋ工艺作了介绍和总结，并与传统的老工艺——腊希工艺及尿素法作了技术经济上的对比。最后分析了国内水合肼生产技术与国际先进水平的差距，指出了国内水合肼生产技术发展和进步的方向。
The world's advanced production techniques for hydrazine hydrate,such as Bayer's process and PCUK method,are summarized and technically and economically compared with traditionary Raschig's and urea ones.The target and task of domestil production processes are also discussed.
