Desulfurization unit ye izini ka minɛn ye min be kɛ ka kibiri bɔ fɛnɲɛnamafagalanw na, a be kɛ ka caya gazi desulfurization la kuranbɔyɔrɔw la minw be baara kɛ ni sɔngɔri- ye, furɛnw na ani kemikali kukala gaziw la. A ka baarakɛcogo ye ko fɛn min be kibiri bɔ (i n’a fɔ kalsiyɔmu wala magnesium oxide) ni kibiri diwɔsidi be ɲɔgɔn minɛ gazi kɔnɔ, o be fɛɛn wɛrɛw bɔ i n’a fɔ kalisiyɔmu wala magnesium.
