The Process   
Glycol is the treatment solvent normally used to remove water vapor from natural gas downstream of an amine sweetening system or as a stand-alone system.

The Problem    
Solid contaminants in the absorber gas feed can cause foaming and tray plugging while solids present in the recirculating glycol stream from inefficient filtration contribute to corosion, fouling of the heat exchangers and reboilers, tray plugging and pump seal failures. Frequent and unnecessary filter changes, off-spec gas, and unnecessary downtime, all contribute to high operating cost.

The Solution     
FBM cartridge (10µm absolute) filters installed at the absorber wet gas inlet will eliminate solids in the wet gas stream and prevent foaming. In addition, cartridges installed both upstream and downstream of the carbon bed in the water rich glycol stream will extend the life of the carbon bed, remove solids and carbon fines, and further protect all downstream equipment.
Rigid FBM cartridges consistently hold contaminants within its graded density structure. This provides uniform filtration performance and a significant life advantage over compresible competitive cartridges. FBM also provides absolute rated performance up to a recommended 35 psid, significantly reducing change-outs.
