Process

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

Problem

Solid contaminants in absorber gas feed causes foaming and tray plugging while solid contaminants present in recirculating glycol stream due to inefficient filtration causes the following problems:

• Corrosion
• Fouling of heat exchangers and reboilers
• Tray plugging
• Pump seal failures
• Frequent & unnecessary filter changes
• Off-spec gas stream
• Unnecessary downtime
• High operating cost

Solution

FBM Filter Cartridges (10µm absolute) installed at absorber wet gas inlet eliminates solids in wet gas streams and prevents foaming. In addition, cartridge filters installed both upstream and downstream of the carbon bed for water rich glycol stream will extend the life of carbon beds, removing solids and fine carbon to protect all downstream equipment.

Rigid FBM Filter Cartridges holds the contaminants within its graded density filter structure. This provides uniform filtration performance and a significant working life advantage over compressible cartridges. FBM cartridge filters also provides absolute rated performance up to a recommended 35 psid, significantly reducing change-outs.
