Alkali solution pipeline
Thread Content
I’m a beginner in the chemical industry, and I would like to ask: our factory is setting up a new production line for sodium pyrosulfite, and sodium carbonate is used to prepare the alkaline solution, with a specific gravity of 1.56–1.58. Why is it necessary to use steam for purging the pipes used to transport this alkaline solution? What are the benefits of steam purging?
There is a chart showing the relationship between temperature and solubility; check it out. The purpose is to prevent sodium carbonate from precipitating and blocking the pipes

Crystallization occurs easily at low temperatures, so it is purged with steam before introducing the alkaline solution.
