Everything you need to know
What dew point should biogas reach before CHP engines?
Target pressure dew point of 3-7°C PDP at 8 mbar ensures no condensation in pipelines or engines under varying ambient conditions. Encon Clean Energy Biogas systems achieve this via staged cooling with automatic condensate drainage.
How does countercurrent heat recuperation work in biogas dryers?
Incoming wet biogas (35-40°C) preheats outgoing dry gas in a gas-gas exchanger, then cools via gas-water exchanger to <5°C dew point. This recovers 30%+ of heat, reducing cooling energy by pre-cooling incoming gas before condensate forms.
What’s the pressure drop across a typical biogas dryer?
Encon Clean Energy’s Biogas systems maintain <5 mbar ΔP across full flow range (100-5000 m³/h) via optimized exchanger geometry and demister design. Low ΔP is critical for blower efficiency in low-pressure biogas lines.
Can biogas dryers handle ammonia (NH3) in the gas?
Encon Clean Energy also designs Biogas Dryers with integrated NH3 scrubbers to bind ammonia (harmful to engines) using condensate circulation before final cooling. Reduces NH3 from 1000ppm to <50ppm, extending engine catalyst life.
How do gas-gas vs gas-water exchangers differ in efficiency?
Gas-gas exchangers recover sensible heat internally (60-70% efficiency) while gas-water needs external chillers (COP 3-4). Encon’s dual-exchanger design combines both for 30% better energy use than water-only cooling.
