摘　　要：分析了中压变换饱和塔改造的原因和依据 ,论述了新型垂直筛板塔的工作原理及其在中压变换饱和塔的应用改造情况 ,对改造前后运行参数和经济效益进行了分析对比。结果表明 ,改造后吨氨电耗下降 19kW·h ,吨氨蒸汽消耗下降 30 0kg ,每月可节省脱盐水 10 0 79m3 。Cause and basis for reforming the middle pressure s hi ft saturation column were analyzed,working principle of the new type of vertic al sieve plate column and its reforming situation in the middle pressure shift s aturation column were discussed,analysis and contrast were made for the operat ing parameters and economic benefit before and after reformation. Result indicat es that the power consumption /ton ammonia after reformation is 19 kW·h reduced ,steam consumption /ton ammonia is 300 kg decreased,demineralized water can be 10 079 m 3 saved monthly.
