Comparison of redox potentials in liquid-phase oxidation and biological desulfurization processes
Thread Content
It is estimated that many experts have come into contact with liquid-phase oxidation and biological desulfurization processes, both of which involve the control of redox electrode potentials. In the former case, this potential needs to be kept between -125 and 25 millivolts, while in the latter case it must be maintained between -350 and -380; the goal in both cases is to oxidize hydrogen sulfide into elemental sulfur. Why is there such a big difference between the two? Does this indicate that the former requires less air than the latter? Additionally, does the redox electrode potential of the former refer to the cell potential between trivalent iron ions and divalent iron ions, or does it refer to the overall potential of the system’s solution?
What does parameter control in liquid-phase oxidation (LOCAT) include?
