目前來(lái)說(shuō)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(gè)流程的工藝都是不同的，下面就和小編一起來(lái)看一看這兩種方法在鹽水處理工藝當(dāng)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(dāng)中，因?yàn)楣に嚨膯?wèn)題，所以鹽水系統(tǒng)當(dāng)中會(huì)有硫酸根積累過(guò)多的情況問(wèn)題。通常來(lái)說(shuō)，鹽水系統(tǒng)在經(jīng)過(guò)一個(gè)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(huì)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(shí)候都會(huì)有這些問(wèn)題，一個(gè)是鹽水精制處理的時(shí)候會(huì)比較困難，而且鹽水精制的成本也是比較高的，甚還有可能因此而導(dǎo)致鹽水被二次污染而且多余的廢棄物也需要進(jìn)行處理。

純隔膜法就不存在硫酸根的積累問(wèn)題，所以不需要在鹽水處理過(guò)程中對(duì)硫酸根進(jìn)行處理。這種氫氧化鉀工藝對(duì)鹽水的要求并不是很高。甚在國(guó)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是全鹵制堿都是可以的，很好的利用的當(dāng)?shù)氐馁Y源優(yōu)勢(shì)。而且這種方法的成本也是比較低的，對(duì)于企業(yè)來(lái)說(shuō)經(jīng)濟(jì)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(dāng)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(lái)說(shuō)，隔膜法的效果是更好的，從成本等方面來(lái)說(shuō)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.
