biogas dryers (biogas chillers)

n biogas plants, the gas produced in biodigesters contains a high concentration of water vapor due to the temperature of the anaerobic digestion process. If this moisture is not removed, it can cause condensation inside pipelines, corrosion of equipment, and operational problems in compressors, blowers, gas engines, and upgrading systems.

To solve this problem, Aqualimpia Engineering e.K., a German engineering company with almost 30 years of experience in industrial biogas technology, supplies high-performance biogas drying systems based on gas cooling technology (Biogas Chillers).

Our systems are designed according to German engineering standards, ensuring maximum reliability, long service life, and safe operation in demanding industrial environments.

Operating Principle

A biogas dryer operates by cooling the biogas to a controlled temperature. As the gas temperature decreases, the water vapor condenses and is separated from the gas stream, producing a much drier and more stable biogas suitable for further utilization.

Typical systems include:

• Biogas heat exchanger for gas cooling

• Industrial refrigeration unit (chiller)

• Condensate separator

• Automatic condensate drainage system

• Monitoring and safety instrumentation

• Complete skid-mounted design for easy installation

Aqualimpia biogas dryers are supplied as fully integrated skid-mounted units, allowing fast installation and reliable operation.

The skid typically includes:

• Industrial biogas chiller

• Stainless steel heat exchanger

• Condensate separator

• Automatic condensate drain

• Gas piping and valves

• Temperature and pressure sensors

• Electrical control panel

• All systems are designed under the supervision of German engineering specialists, ensuring robust construction and long-term reliability.
• Efficient cooling and condensation remove water vapor from the biogas stream, significantly reducing the gas dew point.
• Dry biogas prevents corrosion, condensation damage, and blockages in pipelines, compressors, gas engines, and upgrading units.
• Removing moisture ensures stable and predictable plant operation, especially in combined heat and power (CHP) systems.
• Dry gas reduces corrosion and wear, lowering maintenance requirements and extending the lifetime of equipment.
