介绍了一种尿素法生产水合肼的新工艺－连续蒸发技术，对利用该工艺的5 kt/a水合肼生产装置进行了总结，指出该技术的主要优点是：蒸发过程连续、稳定，洗罐周期较长，解决了连续蒸发系统堵塞问题，盐、碱分别回收利用，实现氯碱生产中盐资源闭路大循环。另外，指出该工艺中需完善的主要问题在于氧化反应问题和多效蒸发问题。

A new process for hydrazine hydrate production with carbamide as raw material is introduced. The 5 kt/a hydrazine hydrate production equiment by the process is summaxized,and its advantages are pointed out as followings: continuous and stable evaporation,longer tank-washing period, nonblockage in continuous evaporation system, separately recovery of salt and caustic soda, and closed recirculation of salt in chlor - alkali production. The main problems needing improving are oxidation and multi - effect evaporation.
