目前來說氫氧化鉀主要是使用離子膜法和隔膜法的工藝，而這兩者各個流程的工藝都是不同的，下面就和小編一起來看一看這兩種方法在鹽水處理工藝當中的區(qū)別吧。
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.
離子膜法的工藝當中，因為工藝的問題，所以鹽水系統(tǒng)當中會有硫酸根積累過多的情況問題。通常來說，鹽水系統(tǒng)在經(jīng)過一個循環(huán)之后，可以讓硫酸根積累量大概處于13.5kg/t100%NaOH左右，這會影響之后成品的效果，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種方法，在使用的時候都會有這些問題，一個是鹽水精制處理的時候會比較困難，而且鹽水精制的成本也是比較高的，甚至還有可能因此而導致鹽水被二次污染而且多余的廢棄物也需要進行處理。

In the ion-exchange membrane process, there will be excessive sulfate accumulation in the brine system due to process problems. Generally speaking, after a cycle of brine system, the sulfate accumulation can be about 13.5kg/t100% NaOH, which will affect the effect of finished products, so sulfate needs to be removed. There are many removal methods, but no matter what method is used, there will be these problems in use. One is that it will be difficult to refine the brine, and the cost of brine refining is relatively high, which may even lead to the secondary pollution of the brine, and the excess waste also needs to be treated.
純隔膜法就不存在硫酸根的積累問題，所以不需要在鹽水處理過程中對硫酸根進行處理。這種氫氧化鉀工藝對鹽水的要求并不是很高。甚至在國內(nèi)許多富有地下鹽礦的地區(qū)，這種方法可以使用大量的鹵水甚至是全鹵制堿都是可以的，很好的利用的當?shù)氐馁Y源優(yōu)勢。而且這種方法的成本也是比較低的，對于企業(yè)來說經(jīng)濟效益是比較好的。
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.
上面介紹的就是氫氧化鉀使用的離子膜法和隔膜法流程當中的鹽水處理工藝的不同，我們看完之后可以了解到，這兩種方法的使用效果都是比較好的，但是相比來說，隔膜法的效果是更好的，從成本等方面來說效果都是比較好的。
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.
