Biogas process
Overall concepts from substrate input to gas utilization
WELTEC BIOPOWER takes a holistic approach to biogas plant construction, handling the technical integration of all process steps throughout the entire production process. This includes integrating the substrate feed, digestion in the anaerobic digester, and connecting the various applications for the biogas and resulting digestion residue. This ensures a fully optimized, efficient turnkey plant.
Gas utilization
Electricity, heat or biomethane
& CO2
There are a variety of ways to upgrade the biogas produced: generating electricity in a combined heat and power plant (CHP), processing it into biomethane for feeding into the grid, or using it as fuel. WELTEC will plan for optimal gas utilization according to your energy and economic goals. While turning biogas into biomethane of natural gas quality, CO₂ is created as a by-product. This CO₂ can be extracted, processed, and used in various ways, such as in the food industry for soda water, as a refrigerant in cooling systems, or to fertilize greenhouses.
WELTEC BLUE WATER
Nutrient management & digestate treatment
WELTEC BLUE WATER separates manure and digestion residues into valuable products: high-quality solid and liquid fertilizers as well as purified water for irrigation or process use. The volume reduction through water separation significantly reduces transport and storage costs. Economical starting at 50,000 tons per year.
WELTEC CONTROL
Take full control of your biogas plant.
The web-based WELTEC CONTROL software gives operators quick access to all relevant system parameters. The individually configurable dashboard allows you to monitor important process data at all times, even on the go, with simultaneous access for multiple users. From energy planning to exportable reports for authorities, intuitive control ensures maximum transparency and efficient work processes.
