Color of amine solution after hydrocracking regeneration
Thread Content
Dear sea friends, the regeneration system of the hydrocracking unit is operating stably. However, the amine solution after regeneration is transparent dark green, while that from the hydrofinishing unit is transparent white. What is the reason for this? How to adjust?
It must be iron ions causing the problem! They should all be transparent; it is recommended to check the anti-corrosion materials used in the system as well as the acid value of the raw materials
MDEA corrosion leads to an increase in impurity content. Purification measures can be taken to remove impurities, restore the solvent’s absorption capacity, and prevent scaling and corrosion.
