Trouble GE Frame 6B GT

Hi Folks,

We have four GE 6B GTs running on crude. Everything was perfect for more than 6 years, but now we are facing serious issues since they started polymer injection on the well, which means we are getting some polymer residue with the firing crude and need to clean the off base on on basse filter every 2 days, and now we are getting LOST OF FLAME because those filters are not providing enough flow....

Onbase filter 5 micron

Offbase 15 micron

Can you suggest anything we may do to improve the situation?
