Separation of ammonia and hydrogen sulfide from methanol.
Thread Content
Methanol contains 1.5% ammonia and 0.7% hydrogen sulfide. Is there a way to separate ammonia from hydrogen sulfide?
Following the method of methanol regeneration in the low-temperature methanol washing process, the methanol is heated; as its temperature rises, the solubility of H2S and NH3 decreases.
This is the issue of methanol regeneration in low-temperature methanol washing
Should it be separated from methanol, or should ammonia be separated from hydrogen sulfide?
All operations take place in the thermal regeneration tower; the reflux tank of this tower requires regular ammonia discharge, while hydrogen sulfide is used to adjust the load on the thermal regeneration tower
How is ammonia removed? Sulfur removal and recovery, or methanol substitution? If it is methanol displacement, what should be done with the methanol that is displaced?
How is it done? If there is any relevant technology, I can share the details below. If you have any suggestions on the direction to take, please let me know. Thank you
