To put it simply, first, buy a large amount of industrial salt, remove impurities by dissolution, precipitation and chemical methods, and then electrolyze in an electrolytic cell, which will separate out hydrogen, chlorine and alkali. You can collect chlorine, liquefy it and store it.

In addition, our company has a large amount of chlorine, a ton of several hundred yuan. If you want a lot, hehe, just buy it directly. If you produce by yourself according to the mode of production, your investment needs 300-500 million yuan. Electrolytic cells need to be imported from Japan or Italy, as well as civil engineering, equipment installation,,,,
