25% concentration sodium hydroxide alkaline solution – issues with the medium used for shutdown purging

2016-05-20View Original

Thread Content

Why do the purging specifications state that water cannot be used as a purging medium when the substance to be purged is an alkaline solution, and instead recommend the use of steam for purging?

Where is it specified? For the replacement of our alkali solution systems, we first rinse them with water.
