Biomasses are the fuel of the biogas plant and are typically manure, industrial organic by-products and crops.
The biomasses are delivered to the plant’s receiving facilities where they are stored until used. These facilities are designed to accommodate the specific types of the biomasses that fuels the plant. (Designed for flexibility)
The feeding module is part of Xergi’s unique indirect feeding system (Accurate feeding) that ensures the correct optimal feeding of the biomasses and prepares the biomass for the digester.
In the primary digester the biomass is mixed efficiently (High Mixing Efficiency), the anaerobic digestion process takes place and the biogas is produced. A high process temperature (Ideal process temperature) is chosen for greater efficiency when possible.
The secondary digester is used for gas storage and also hosts a gas purification system. Some biogas is also being produced here.
The gas engine in the CHP unit transforms the biogas into energy in the form of power and heat
The digestate (the degassed biomass) is placed in an end storage facility a final step before it can be used on nearby fields.
An advanced process control system (User friendly SCADA) runs and monitors the whole plant. It records information, providing feed-back to the operator about the status of individual components and the entire system. The control system therefore is 'the heart' of the biogas plant. It incorporates the biological process knowledge and operational experience of our company.
