Q: I’m using a pretty corrosive wet process to produce phosphoric acid. It involves taking phosphate rock and the addition of concentrated (93%) sulfuric acid in a series of well-stirred reactor. Any ideas on bolting that won’t corrode my bolts and fasteners? A: Since your process is exposed to both … Continue reading →
