FAQs about Vilter renewable natural gas solutions for digesters
What support does Vilter offer for RNG operations?
Vilter provides application expertise, configure-to-order or engineer-to-order solutions and comprehensive aftermarket support across North America. From system design and commissioning through long-term operation, customers have access to experienced engineers, OEM parts and factory-trained service professionals to help maximize uptime throughout the equipment lifecycle.
What compressor is used for biogas upgrading?
The Vilter VSGX is the purpose-built compressor for feed gas compression in biogas upgrading in mid- to large-scale digester applications. Its single screw design delivers reliable, continuous compression across flow rates from 800 to 2,100 scfm. Vilter has single screw products that range from 120 to 3000 scfm that are used in biogas upgrading for feed gas compression upstream of CO2 removal, compression surrounding Nitrogen removal, and product gas compression.
How is biogas upgraded to pipeline-quality RNG?
Raw biogas is boosted and dehydrated, then contaminants like hydrogen sulfide and Volatile Organic Compounds (VOCs) are removed, then the biogas is compressed and passed through purification processes that remove CO2. If Nitrogen and Oxygen are present, Nitrogen and Oxygen removal is then required. The final step is product gas compression to pipeline pressure or CNG. The Vilter VSGX provides the stable, pulse-free feed gas compression that downstream membrane separation and upgrading systems require to produce pipeline-quality RNG.
Why is gas compression important in the RNG production process?
Compression is the critical link between raw biogas capture and renewable natural gas production. Compression is required for subsequent removal of carbon dioxide and/or nitrogen to occur. Reliable compression helps downstream purification systems operate efficiently while meeting required pressure, flow and pipeline specifications.
What types of facilities can produce RNG through anaerobic digestion?
Dairy farms, municipal wastewater treatment plants and anaerobic food waste digesters are the primary facility types. The Vilter VSGX is specifically designed to handle the variable biogas compositions found across all three of these organic waste streams.
Does Vilter offer local support for biogas compression?
Yes. Vilter maintains a comprehensive North American service and aftermarket network, ensuring localized access to technical support, replacement parts and trained service professionals. This coverage spans the full equipment lifecycle, from commissioning to long-term operational maintenance.
Are Vilter RNG solutions manufactured in North America?
Yes. Manufactured in Wisconsin and backed by North American engineering and service resources, Vilter helps simplify project execution while providing responsive support throughout the life of the system.
