Calculation of the amount of non-purified air used for LPG desulfurization
Thread Content
The liquefied gas desulfurization and dewaxing system uses cobalt titanium cyanosulfide as a catalyst; the hydrogen sulfide level after desulfurization is high – is it due to poor regeneration of the alkaline solution or poor separation of disulfides? Are there any good methods to improve the extraction of disulfides? Also, how is the air supply volume for alkali solution regeneration calculated?
High hydrogen sulfide levels are a problem associated with amine-based desulfurization; the hydrodesulfurization system can absorb some of the hydrogen sulfide, but this is unrelated to the regeneration process.
How much alkali is needed to remove hydrogen sulfide using an alkaline solution? Your desulfurization system is not very effective at removing hydrogen sulfide; address the problem at its source. The high hydrogen sulfide level after desulfurization of alcohols indicates that the concentration of the alkaline solution is too low……
