STATERON P-Series
Pressure Swing Adsorption (PSA) is based on the concept that different components have a different absorption potential than others. In this case, CO2 is adsorbed in the PSA columns that are filled with molecular sieve media, while CH4 is concentrated to produce RNG.
The PSA process used in the system is a physical process widely applied in the gas industry to purify different gas streams for a variety of industrial applications and can be explained in two simple process steps: Adsorption and Desorption. The system automatically synchronizes adsorption/desorption of different vessels to allow for the production of a steady and continuous biomethane quality, even at varying inlet gas quality or volume flow. Unlike other upgrading systems and due to a special guard bed, the STATERON PSA system is less sensitive to the performance of the activated carbon filters.
What sets the STATERON P-Series apart?
- High methane recovery (> 98%)
- Lowest energy consumption of all RNG upgrader technologies
- Simple process control and high availability (> 99% availability)
- Fully automatic start-up and turndown function
- Methane content in the product gas can be adjusted to meet gas grid specifications
- No pressure surges in the adsorbent PSA columns and no dust formations
- Adsorbent lifetime >15 years
- No chemical, solvent or biological risks
- No process water required and no waste water produced
- No thermal oxidizer needed or tail gas to flare
- Modular design and shop fabrication for reduced onsite installation
- Local construction & commission support services, as well as ongoing operation & maintenance (0&M) support across North America
