The main challenges in this sector
The main challenges in this sector
Highly corrosive and humid gas streams
Biogas often contains Hâ‚‚S, COâ‚‚, and moisture, which are highly corrosive. Heat exchangers must be designed with materials that resist these aggressive compounds.
Temperature sensitive digestion processes
Anaerobic digestion depends on stable thermal conditions. Temperature drops can disrupt biological activity and reduce methane output.
Energy recovery from hot effluents and CHP
Waste heat from digesters or CHP systems can be recovered to reduce steam or fuel consumption and improve energy efficiency.
Fluctuating gas composition and flow
Biogas processes are dynamic. Heat exchangers must be able to adapt to variable gas quality, humidity, and flow rates without compromising performance.
Our involvement in the sector
Nexson offers thermal technologies adapted to the full biogas chain from digester heating to biomethane purification ensuring efficiency, durability, and sustainability.
Turning organic waste into energy with thermal precision
Welded construction for long term leak protection
Our fully welded plate heat exchangers offer zero leakage, ideal for processing volatile and corrosive gases. This ensures long term integrity even under continuous operation.
Thermal regulation of digesters and sludge heating
By recovering heat from hot water or CHP sources, Nexson exchangers ensure precise and uniform heating of the digester, boosting methane yield and process stability.
Gas cooling and dew point control
Efficient gas cooling before treatment improves Hâ‚‚S removal and enhances the efficiency of membranes or PSA systems in biogas upgrading.
Materials for sulfur and ammonia rich media
Our solutions are built with 316L, duplex, or custom alloys to resist degradation from Hâ‚‚S, ammonia, and acidic condensates, ensuring high durability and performance.
