Single Screw pushes the limits of compression.
We've applied it to gas compression.
Vilter sets the industry standard for gas compression solutions for renewable natural gas (RNG), including landfill, wastewater treatment, livestock waste and food waste. Thanks to its proven Single Screw compression technology, Vilter offers one of the highest levels of reliability on the market.
Vilter's technology and industry expertise ensure the availability and reliability needed in demanding renewable natural gas (RNG) applications. More than 145 operating plants rely on Vilter's unique screw compression technology for consistent, quality production.
There is great variability in gas quality specifications, negotiations with utilities, raw materials, local and federal incentives, and the different entities involved in a project. Vilter's innovation and expertise can help you navigate the options available, including:
- Booster skids to increase the initial biogas pressure in order to maintain a positive pressure during contaminant removal and optimise the inlet pressure to the main compressor.
- Low and high-pressure cooling skids to dehydrate the biogas upstream and downstream of the main compressor
- Single Screw technology to pressurise biogas upstream of carbon dioxide removal technology
- Single screw recirculation and vacuum compressors for nitrogen removal, depending on the technology chosen
- Single Screw compressor technology to increase biomethane pressure up to pipeline pressure, including the unique Vilter High Pressure Low Displacement (HPLD) compressor model
- Gas booster to power a gas turbine for cogeneration technology (CHP).
