我公司是90万吨焦化配套的化产回收车间，脱硫是以氨法脱硫，现存在的问题主要是生产过程中，每天脱硫液增长快，造成被迫外排，同时也检查了补水阀及换热器也没有发现有漏液的现象；求高人指点分析原因及解决办法；

这个需要你具体描述下你们的流程，设备，做详细分析。氨法脱硫是也有很多不同的

蒸氨氨水冷凝器有没有泄露？考虑是外部的水进入脱硫液。脱硫溶液质量怎么样？

确定有进水点，我们是纯碱法，曾经出现过类似问题，

个人认为：预冷温度控制不好，煤气预冷后温度偏高，不能最大限度降低煤气中夹带水分，可能造成进脱硫塔煤气温度偏高，而脱硫液温度可能偏低，造成在脱硫塔中煤气中大量夹带的水份被冷凝下来。需要具体说明各项指标控制情况，具体分析。

脱硫液温度比煤气温度要高1-2℃，不然会把水洗下来的
