The important focus on carbon footprint reduction, and the utilization of waste as green energy, is pushing requirements for the equipment & technologies involved. Our vision is to help you achieve an efficient, eco-friendly biogas plant operation, by providing leading-edge sustainable gas solutions. Nowadays biogas goes beyond the digestion of energy crops and manure. 

The increased utilization of bio-waste is resulting in raw biogas containing previously disregarded impurities such as volatile organic compounds (VOCs). These contaminants, predominately terpenes and ketones, not only endanger the pipe integrity of the gas grid, they can also impact the odorization of the gas, leading to safety issues when gas leakages cannot be detected (smelled) anymore.

OBTAIN HUGE OPEX SAVINGS
BioSENSE is developed for biogas producers that want to increase their profitability and reduce their risks. BioSENSE provides up to 2% increased uptime, up to 25% lower activated carbon usage and up to 5% increase utilization of your biomass and membrane warranty. We do this by delivering a new measuring technique that can measure the high risk contaminations like Terpenes and Ketones in the raw and cleaned biogas, as demonstrated by ARN & Wijster. 

BENEFITS:

• Developed specifically for the application
• Unparalleled in robustness, reliability and operability

Typical Applications

• Agricultural plants with bio-waste as co-digestate
• Bio-waste treatment plants (industrial, supermarket & residential sources)
• Anaerobic digesters on waste water treatment plants 

Added Value

• Reduce operational costs for activated carbon by up to 30%
• Increase uptime by 1-2%
• Safeguard membrane performance and service life
• Reduce biomethane production costs by 3-5%

Optical absorption spectroscopy
The optical absorption spectroscopy used in the BioSENSE operates with a UV light source (1) which emits light that penetrates a gas sample in a measuring cell (2). Here light is partially absorbed by the gas molecules. Since each molecule has its own typical absorption spectrum, it is possible to simultaneously determine the concentration of different components of the gas. The remaining light is captured by the receiver (3). The receiver splits the light into narrow wavelength bands using an optical grading (4). Finally the light is captured by a CCD (5) and transformed into an electrical signal for processing. By adapting spectrometric technology to the analysis of biogas, its typical contaminants like VOCs, H₂S and NH₃, can be continuously monitored.
