Hello All,
Asking your expertise in LPG treating systems, in our case the initial treatment for the LPG is the amine absorber tower wherein H2S in the LPG feed is captured by amine solution (25% DEA) and for past months the rich amine quality specifically the amine loading (mol H2S/mol DEA) have been out of spec (greater than 0.4).
The initial correction is to increase the amine flow in the tower however it is reaching the maximum limit.
Hoping for your insights in this matter on possible mitigations and optimization of amine demand.
Thank you very much!
