PROGECO – Biogaz Drying System

Biogas from anaerobic digestion is saturated with water vapour that has a significant negative impact on the performance of energy recovery units. Removal of moisture is achieved by means of cooling down the biogas flow so that moisture turns into condensate water that can be easily separated, collected and discharged. The system is based on an air-cooled fully automatic water chiller and a water/biogas heat exchanger. The two units are connected by a recirculating water+glicole hydraulic circuit. Condensate water separated in the heat exchanger is collected inside a knock-out drum from which is automatically disposed. The system is designed as package unit; chiller is supplied separately, for installation in non-hazardous area.
