降低中、低压系统尾气放空氨损失的措施

Measures for Reducing the Ammonia Loss from the Tail Gases Venting in the Medium-low Pressure System

为降低中、低压系统放空尾气中的氨含量 ,作者对高压系统操作条件的优化进行了说明 ,同时对中、低压系统本身存在的问题进行了分析和改进 ,使尿素氨耗维持在 5 78kgNH3/t·u的水平 。

In order to reduce the ammonia loss from the venting tail gases in the medium low pressure system, the author describes the operating condition optimization of the high pressure system, at the same time the present problems in medium low pressure system itself are analyzed and improved to make the ammonia consumption per ton of urea maintaining at a level of 578 kg NH 3/ton urea, in addition further improvement is also presented.
