Biogas is a promising renewable energy source, primarily composed of methane, carbon dioxide, nitrogen, oxygen, and trace impurities such as hydrogen sulfide (H2S), siloxanes, hydrocarbons, and water vapor. To utilize biogas effectively as a raw material for energy production or other products like biomethane, it must undergo a thorough cleaning process to remove harmful impurities. 

BTS-MPdry is an innovative technology that offers an efficient way to clean biogas, resulting in numerous benefits for the biogas industry. 

Biogas Cleaning 

Biogas can be derived from uncontrolled processes, such as landfills or lakes, or controlled processes, like wastewater treatment plants (WWTPs). Irrespective of its origin, biogas is considered a "dirty gas" due to the presence of external and internal impurities that must be eliminated for optimal use. 

BTS-MPdry: An Innovative Biogas Cleaning Technology 

BTS-MPdry is a cutting-edge biogas cleaning system that effectively removes both external and internal impurities, ensuring the high-quality utilization of biogas. The cleaning process involves: 

• Desulfurization (H2S removal) 
• Biogas drying (water vapor removal) 
• Biogas polishing using activated carbon filters 

Case of Study: Alcala Oeste WWTP, Madrid, Spain 

The BTS-MPdry technology was implemented at the Alcala Oeste WWTP in Madrid, Spain, with impressive results. The system demonstrated exceptional performance in removing impurities, leading to higher biogas quality, reduced maintenance costs, and improved exhaust gas emissions. The study indicated substantial cost savings and enhanced profitability for the CHP system. 

Conclusion 

BTS-MPdry presents a game-changing solution for the biogas industry by effectively cleaning biogas, removing harmful impurities, and promoting sustainable and efficient energy production. This technology optimizes the operation of biogas-based machinery and contributes to a greener environment through reduced emissions.  

Cleaning biogas with BTS-MPdry opens new possibilities for harnessing biogas as a reliable and clean energy source.
