Natural Gas Sweetening

• Foaming and reduced production rates due to hydrocarbon liquid and particulate ingression into the amine loop.
• Foaming, process efficiency loss and increased maintenance due to fouling of the contactor, lean-rich exchanger, regenerator and reboiler due to dirty amine (green, brown, or black in color)
• Rapid cleanup need

Improve your sour gas sweetening productivity and reliability via effective liquid and solid removal upstream of the contactor to protect the amine loop.

• KO pots, mesh pads, cyclonic devices and conventional filter-separators may not effectively remove aerosol-sized liquid hydrocarbon droplets or fine solids.
• High efficiency SepraSol™ Plus liquid/gas coalescers and Medallion™ HP liquid/gas coalescers provide 99.999% removal at 0.3 microns per the DOP test and 1 ppb downstream per the modified ANSI/CAGI-400-1999 test. Both provide excellent foaming and fouling protection.

Reduce the gaps in productivity, reliability and maintenance cost through effective solids control in the amine loop.

• Solid contaminants in amine systems are mostly very fine corrosion products that may not be adequately removed by filters that exhibit unloading, media migration, channeling or poor sealing.
• A range of absolute and nominal rated filter elements is available to reduce suspended solids to <5 ppmw, keep the amine clear or pale yellow in color, and reduce related foaming and fouling issues.
• For enhanced solids control, add filtration to the rich side. Total sour gas worker exposure will typically be lowered due to the reduced system maintenance on the rich side.

• Apply mobile filter or liquid/liquid coalescer skids.
