Frequently Asked Questions
How do I select the right biogas blower?
Key criteria:
- Required flow rate (Nm³/h)
- System pressure (suction and discharge pressure, including pipe losses and equipment)
- Gas composition (CH₄, CO₂, H₂S content, trace compounds)
- Safety standards (ATEX zone classification)
- Efficiency and noise
We typically use side-channel blowers or rotary lobe blowers. Encon partners can help you to select blowers tailored for biogas conditions.
What ATEX rules apply to biogas equipment?
Biogas is classified as a potentially explosive atmosphere. ATEX (EU Directive 2014/34/EU) requires equipment in contact with biogas to be certified for the correct zone classification:
- Inside digesters/pipelines: typically Zone 1 or 2 (never Zone 0 for moving gas).
- Electrical equipment, blowers, sensors, and flares must be ATEX-certified.
We conduct ATEX risk assessments to ensure compliance and select safe equipment.
What is the dew point of biogas, and why does it matter?
The dew point of biogas is the temperature at which water vapour in the gas condenses into liquid. It depends on the relative humidity and pressure of the gas. Typical raw biogas is saturated with water at digester temperature (30–40 °C). If biogas cools down in pipes or vessels, condensate will form.
Controlling dew point is crucial to avoid water accumulation, corrosion, and H₂S dissolution. That’s why biogas dryers and condensate traps are part of most systems.
How do relative humidity and dew point change after pressurising biogas?
When biogas is compressed, its ability to hold water vapour decreases, and the dew point rises. For example:
- At atmospheric pressure, saturated biogas at 35 °C has a dew point of ~35 °C.
- If compressed to 200 mbar(g), the dew point may increase by several degrees.
This means condensate can form downstream of blowers or compressors unless the gas is cooled and dried. Proper design accounts for these shifts to protect equipment.
What causes pressure drop in a biogas pipeline, and how is it calculated?
Pressure drop arises from friction, fittings, bends, valves, and filters. It depends on:
- Pipe length and diameter
- Gas velocity
- Surface roughness
- Gas density (biogas is lighter than air but viscosity matters)
We design pipelines to keep gas velocity low (usually <10 m/s) and pressure drop minimal, since blowers have limited pressure capability (often 30–500 mbar). Correct sizing reduces operating costs and ensures stable system operation.
How is condensate removed from a biogas system?
Condensate forms whenever gas cools below its dew point. Removal methods include:
- Condensate pots/traps installed at pipeline low points
- Automatic drains with water locks to prevent gas leakage
- Condensate separators integrated in gas cleaning systems
Proper condensate management prevents blockages, corrosion, and microbial growth in pipelines.
