Differences in the use of sea salt and well-mined salt by two alkali-producing companies
Thread Content
Dear sea friends and teachers: Some alkali plants use sea salt, some use rock salt, and some use a mixture of the two. What is the difference between them? Can’t sea salt and mineral salt be used interchangeably either?
Sea salt refers to salt that has been dried in the sun, while table salt refers to refined salt. The difference between the two is that table salt goes through a purification process, whereas sea salt does not. Therefore, chlor-alkali plants that use sea salt consume more refined products.
It is best not to mix the two together, and certainly not to switch between them arbitrarily. Industrial production requires stability; mixing them leads to unstable levels of impurities, which can cause the pre-treatment process to become turbid again, ultimately affecting production. Switching between them casually has an even greater impact on production.
