Why choose GM
10 reasons to choose GM
ENVIRONMENTAL PROTECTION
Methane losses in Off-gas vented to atmosphere are lower than 0.1% of total methane in Biogas feed: no Off-gas post-treatment needed. GM-HPC (Hot Potassium Carbonate) technology is a BAT (Best Available Technique) thanks to the low level of pollutants emission and to the low consumption of feedstock, chemicals, water and energy.

METHANE RECOVERY > 99,9%
Methane recovered from raw Biogas is higher than 99.9%. A higher methane yield by some percentage points increases significantly the profitability of the investment compared to other upgrading technologies.

ENVIRONMENTAL - FRIENDLY NO CHEMICAL CONSUMPTION
The water based K2CO3 solution is not volatile and does not degrade, unlike the amine based scrubbing solutions. GM process is a chemical absorption, with no chemicals consumption, unlike water scrubbing technology, which needs chemicals for process water conditioning.

MINIMUM ELECTRICITY CONSUMPTION
GM Biogas upgrade process requires minimal power: 0.15 to 0.2 kWh/Nm3 of Biogas, depending on the requested Biomethane pressure at battery limits. Compared to membrane multi-stages process, no Biogas is recycled to compressor. Compared to water washing, GM process is not affected by weather condition and power consumption is less due to lower solution circulation and to negligible recycling to compressor of methane absorbed by washing solution.

LOW MAINTENANCE COSTS
GM process for Biogas upgrading to Biomethane ensures low maintenance costs, thanks to unit’s robust and simple design. Biogas compressor is the most critical item.

BEST EFFICIENCY IN CO2 REMOVAL
Residual CO2 content in produced Biomethane is typically lower than 1%.
