目前来说氢氧化钾主要是使用离子膜法和隔膜法的工艺，而这两者各个流程的工艺都是不同的，下面就和小编一起来看一看这两种方法在盐水处理工艺当中的区别吧。
At present, potassium hydroxide mainly uses the processes of ionic membrane method and diaphragm method, and the processes of each process are different. Let's take a look at the differences between these two methods in brine treatment process with Xiaobian.
离子膜法的工艺当中，因为工艺的问题，所以盐水系统当中会有硫酸根积累过多的情况问题。通常来说，盐水系统在经过一个循环之后，可以让硫酸根积累量大概处于13.5kg/t100%NaOH左右，这会影响之后成品的效果，所以需要去除硫酸根。去除的方法是非常多的，但是不管是用的是何种方法，在使用的时候都会有这些问题，一个是盐水精制处理的时候会比较困难，而且盐水精制的成本也是比较高的，甚还有可能因此而导致盐水被二次污染而且多余的废弃物也需要进行处理。

纯隔膜法就不存在硫酸根的积累问题，所以不需要在盐水处理过程中对硫酸根进行处理。这种氢氧化钾工艺对盐水的要求并不是很高。甚在国内许多富有地下盐矿的地区，这种方法可以使用大量的卤水甚是全卤制碱都是可以的，很好的利用的当地的资源优势。而且这种方法的成本也是比较低的，对于企业来说经济效益是比较好的。
The pure diaphragm method does not have the problem of sulfate accumulation, so it is not necessary to treat sulfate in the process of brine treatment. This potassium hydroxide process does not have very high requirements for brine. Even in many areas rich in underground salt mines in China, this method can use a large amount of brine or even total brine to make alkali, which can make good use of the local resource advantages. Moreover, the cost of this method is relatively low, and the economic benefit is relatively good for enterprises.
上面介绍的就是氢氧化钾使用的离子膜法和隔膜法流程当中的盐水处理工艺的不同，我们看完之后可以了解到，这两种方法的使用效果都是比较好的，但是相比来说，隔膜法的效果是更好的，从成本等方面来说效果都是比较好的。
The above describes the difference between the brine treatment process of the ion-exchange membrane method and the diaphragm method used in potassium hydroxide. After reading, we can understand that the use effects of these two methods are relatively good, but compared with the diaphragm method, the effect is better, and the effect is relatively good in terms of cost and so on.
