8.5 Reduction of SO2 and NOx emissions (SL)

This video is very easy to understand

Hi again! Is it necessary to revise the reduction of nitrogen oxides? The syllabus point only mentions distinguishing between the pre-combustion and post-combustion methods of reducing sulphuric oxides. Your videos are super helpful btw, thanks heaps!

+Luke Davies You are correct in that the syllabus only mentions reduction of the oxides of sulfur, both pre and post combustion. There is no mention of the reduction of oxides of nitrogen, but I have covered it in this video just in case. And thanks for the feedback, I'm glad my videos are helpful for you.

Right, it's good to know about for reference I suppose! Another thing, would you think that it's necessary to memorise the equations for Flu-gas desulfurisation? There's so much to take in, and I wouldn't want to memorise it when I could be obtaining more vital chem knowledge (assuming it wasn't necessary)!

+Luke Davies It's difficult to know what the IB will ask about in the exams. To be honest, I think you could be ok without memorizing all of those equations but just having a general idea of the process.

what year is this for

[@MSJChem]

This is for the current syllabus, however the part about the reduction of NOx emissions is not relevant so can be ignored.

Isn't fluidized bed combustion a factor for climate change as the CO2 is produced?

[@MSJChem]

You could say that, but it does reduce the amount of SO2 released into the atmosphere and therefore the formation of acid rain.
