Designed to capture more than 98.5% of the methane and purify it to pipeline quality renewable natural gas (RNG), Sorpt.X SB biogas upgrading/purification systems remove H2S, CO2, and light siloxanes from the digester gas produced at agricultural and animal waste (manure) facilities, wastewater treatment plants, and landfill sites.
When purified, biogas can be added to the natural gas grid and used in cogeneration applications to produce electricity, generate heat, and fuel vehicles.
Depending on the characteristics of the biogas stream, Dürr offers both water scrubbing and membrane separation solutions for biogas upgrading/purification.
Fast, Simple Installation
Each system is skid-mounted and modular in design, which requires a smaller operational footprint and allows greater integration flexibility at the application site. Stainless steel wetted system components are factory assembled and tested to performance parameters.
Every skid package comes fully assembled, wired, and component tested at the factory to the extent possible prior to shipment. All equipment ships on commercial trucks. This shortens the installation timeframe and helps ensure an effective start-up. Dürr can also provide full turnkey installation and startup services, preventive maintenance, and fulfill future service/parts requirements.
An advanced electronic control system automatically optimizes the system for high gas yield. Gas analyzers provide continuous monitoring of the inlet and outlet biogas, reporting H2S, CH4, CO2, and O2 levels. The entire control system, variable frequency drives, and gas sample monitoring system are located in a climate-controlled, lighted, skid-mounted “control house” with locking access door. The operation of the system can be monitored and adjusted remotely.
Water scrubbing and membrane separation are effective methods for purifying biogas from digester, wastewater treatment, landfill or other biogas streams. The process equipment of the Sorpt.X SB biogas upgrading/purification system can be tailored to specific applications to remove particulate, H2S, CO2, H2O and siloxanes, and can capture more than 98.5 percent of the methane.
Tail Gas Treatment
Dürr offers a range of oxidizer systems to treat tail gas for all popular biogas upgrading/purification technologies, including water scrubbing, pressure swing adsorption (PSA) and membrane systems. The systems handle a wide range of methane content and in most cases, run fuel-free by utilizing the tail gas as the energy source.
H2S and Siloxane Treatment
Partnerships with world-class developers of H2S and siloxane removal systems enables Dürr to provide a complete biogas upgrading/purification system that meets its customers’ design requirements.
Our strong vendor management and service division provides substantial cost-savings to our customers while ensuring viability of the entire system.
