Unit 4: Physical Conditions for Desulfurization

Chemistry Ain’t Enough!

You need more than chemistry to make it work – you need to get physical! Ever have a heat that won't desulfurize even though the slag analysis is good? You just may have a few things to learn from a sponge! In this unit we are taking on Desulfurizing Conditions 4 and 5, the physical slag characteristics needed before we get the lonely sulfur and lime to meet each other. (Also includes a good review of everything we've covered so far.)
