Does the solubility of hydrogen sulfide in oil increase or decrease as the temperature rises?
Thread Content
We all know that the solubility of hydrogen in petroleum products increases as the temperature rises. So, does the solubility of hydrogen sulfide increase or decrease?
Personally, I think high pressure increases solubility.
Hydrogen sulfide decreases as the temperature rises
In solutions such as water, carbonate salt solutions, and MDEA, it decreases as the temperature rises; no solubility curve in gasoline has been found
The solubility of gases generally decreases gradually as the temperature rises, at constant pressure. The same is true for hydrogen sulfide. . . :lol
Not necessarily; I remember that for gases, their solubility seems to decrease as the temperature rises. It’s just a guess; it’s not necessarily correct.
The solubility of hydrogen sulfide in oil products decreases as the temperature rises.
As the temperature rises, the solubility should decrease accordingly; therefore, the solubility of hydrogen sulfide in oils decreases as the temperature increases. This is based on Dalton’s law of partial pressures – you can look that up
Only hydrogen and water see an increase in their solubility in oils as the temperature rises, and their solubility increases with rising pressure; whereas for all other gases, solubility increases with rising pressure but decreases as the temperature rises
In oil, the solubility of hydrogen sulfide increases as pressure rises； As the temperature rises, solubility decreases. Therefore, high temperature and low pressure are conducive to the removal of hydrogen sulfide from oil products.
