Biogas Upgrading Process
The biogas obtained through the digestion of waste, prior to the elimination of impurities, is subjected to the valorGas® system under conditions of pressure, temperature and humidity specifically defined to achieve the highest selectivity between CH4 and CO2, using the speed difference of permeation between the two gases.
CO2 permeates faster and CH4 is concentrated and obtained as retentate.
The separation process is carried out at pressures between 12 and 20 bar and in a temperature range between 30 and 70ºC, being essential the appropriate design to achieve the best operating performance according to the composition of the biogas to be enriched.
The valorGas® system also integrates a sophisticated control system that allows a high level of automation while ensuring maximum stability.
3 Phase Separation
The highest possible selectivity in a single membrane separation stage is insufficient to achieve a high percentage of recovery.
For this, the patented Sepuran® three-stage separation process is applied, where each partial gas flow (permeate and retentate) is led through two new membrane units arranged in series.
Thanks to the recirculation of low-quality waste gas to the treatment head, it is possible to avoid any loss of performance while obtaining the highest possible concentration of CH4 and CO2 in the production lines.
In this way, a high purity is obtained in the Biomethane and CO2 flows and a significant reduction in operating costs.
