Amine scrubbing

A robust and economic technology with unique energy efficiency

Through its AE-AMINE range, Arol Energy is the only company in France to offer the amine scrubbing technology. This patented technology, developed exclusively with IFP Energies Nouvelles, is unmatched by the other technologies available on the market in terms of energy efficiency.

The principle of the amine scrubbing technology:

Biogas is decarbonized at atmospheric pressure in absorbing columns
A unique amine-based solvent captures the CO₂ and H₂S leaving only the methane
The heat supplied allows the solvent to be regenerated, releasing the CO₂ and the H₂S
This technology was first used in the 1930s and has
been used for natural gas since the 1950s
