Methane SlipRec Unit for Existing Water Scrubbing
With our patented SlipRec unit, the methane slip is reduced significantly and the overall performance of water scrubber-based biogas upgrading plants is improved significantly.
- Methane recovery >99,9%
- Methane slip <0,1%
- Eliminates the need for thermal oxidation (RTO, CTO)
- Low power consumption
- Reduces GWP (Global Warming Potential)
- Low power consumption
- No need for H2S / VOC polishing
- No need for chemicals
- No need for heat
- All-electric process – no heat source required
One of the less desirable characteristics of water scrubbing-based upgrading plants has until now been a high methane slip. Existing plants have today a direct loss of unutilized biomethane of between 1 and 3% (direct loss of production capacity and revenue) – diluting the green footprint of the entire biogas plant.
A common way to overcome the biomethane emissions has been, to equip the plant with an RTO unit (Regenerative Thermal Oxidizer). It burns off the methane slip and converts the just produced renewable energy into CO2 and heat, which is not desirable either from an environmental or financial point of view.
Airco Process Technology’s Slip Rec unit changes the game.
In other words, with a SlipRec unit, existing biogas upgrading plants using water scrubbing technology will be equal to or surpass the performance of other upgrading technologies.
