How does sodium hydroxide get into the amine solution? What is the pH value of the amine solution? Is there any effect on hydrogen sulfide in the lean solution?
There’s a leak in a ball valve on the equipment; the pH level is 13–14, and there’s severe crystallization
A pH of 13–14 indicates a significant amount of alkali leakage; normally, the pH value in MDEA is around 10. The result may affect the regeneration efficiency, leading to excessive hydrogen sulfide levels in the lean solution. It is recommended that you hire a professional company specializing in amine liquid purification to remove sodium ions, thereby lowering its pH value.
Have you resolved the problem with your amine solution now? I can help you come up with some solutions
If there are any issues with the amine solution in any equipment, feel free to add me on QQ at 601121149. I hope I can be of assistance to you
What methods do you have to remove sodium ions from the amine solution? If you don’t mind, I’d like to introduce this to everyone, as many organizations are currently facing the problem of excessive sodium levels.
Sodium ions can be removed using cation exchange resin; this resin can also remove at least 80% of thermally stable salts. If there is a significant amount of dust in the amine solution, high-precision filters can be utilized to remove most solid particles larger than 1 micron, thereby restoring the original color of otherwise discolored, low-quality amine solutions. Should any issues arise with a particular amine solution, we can discuss them together and find appropriate solutions
Do you have any mature operational experience? How can one prevent the entrainment of amine solution when removing sodium ions using cationic resins (since the amine solution is also a cation)? Moreover, thermally stable salts usually need to be removed using anion exchange resins. So, can your cation exchange resins remove both sodium ions and thermally stable salts?
Ultrafiltration + ion exchange has become a standard feature in large-scale amine solution plants; the commercial term for this process is amine activation or amine regeneration
