Control of liquid sulfuric acid concentration
Thread Content
To control the pH value in liquid sulfur, it has been suggested to use solid alkalis and limestone, but concentrated alkalis have also been proposed. Which one is better? How can we control the amount added? What do you all think? I personally believe that using strong alkali is a good option: firstly, it makes it easier to control the amount added, and secondly, it’s simpler to add it, which helps prevent the work environment from becoming unfavorable ； It’s just a waste of the heat-retaining steam. If there are any mistakes, please let me know! !
This issue has been discussed; please check whether it is better to use soda ash or lime for the neutralization of liquid sulfur: http://bbs.hcbbs.com/viewthread.php?tid=231506
