Natural Gas Plant Amine Unit – Bags To V-Max Case Study

A Louisiana Gas Plant was having issues cleaning their amines to an acceptable level. Upon having quality discussions about the issues they were having we learned that in addition to their Amines being contaminated, they were utilizing bag filters and they were changing them weekly.

The plant had an 8 bag pre-filter feeding to a carbon bed and a 4 bag after carbon filter unit. After opening the pre-filter to measure the vessel, we found quite a bit of catalyst carryover from the reactor bed. When examining the post carbon filter we found that the amines had actually darkened from carbon carryover.
