Hi ;
I hope you are doing well.
First of all, I would like to apologize for an issue in the latest email related to the article "4 Key Factors Affecting PSV Sizing & Operation".
There was an issue in publishing the article at the time of writing the email and it was discovered too late. But now this issue is solved and you can access the article. So please accept my apologies for that. 🙏
Now let's go into the main subject of this email. I recently wrote a new article on the various design considerations that must be taken into account when engineering amine gas sweetening systems. One important factor I discussed is managing corrosion caused by rich amine solutions.
As a refresher, rich amine absorbs acid gases like H2S and CO2 from the sour gas stream. This makes the amine corrosive, especially after absorbing those gases. Left unchecked, corrosion can cause significant damage to pipes and equipment over time.
API guidelines recommend keeping amine velocities below 6 ft/s to reduce the risk of erosion. High velocities can wear away the protective corrosion layer and lead to further corrosion issues down the line. Properly sizing pipes to ensure safe amine velocities is an important design step.
If you'd like to learn more about additional factors like inlet temperatures, amine degradation, filtration needs, heat exchangers and more, check out my full article on amine gas sweetening system design considerations. The link is below or you can find it on my website.
Let me know if you have any other questions!
Regards;
Mohamad
