Ifpexol™ IFPEn Integrated Process
for Natural Gas Full Treatment
Concept
• Refrigerated methanol as absorption solvent:
- simple, non foaming, non corrosive
• 2 independent process steps:
- Ifpex-1 for simultaneous water
and hydrocarbon dew pointing
- Ifpex-2 for acid gas removal
• Meets sales gas specifications
Ifpex-1, elegantly Simple,
simply Elegant
• Water and HC dew points down to -90°C (-130 F)
• No regeneration system, no heater
• Minimized CAPEX, weight and footprint
• No gas emissions
• Pure water is produced (< 50 ppm
residual methanol)
• More than 15 references since 1992 (including offshore) with various capacities up to 350 MMSCFD
