Biogas Upgrading

Biogas Upgrading is the process of converting Biogas to Biomethane or RNG (Renewable Natural Gas). Biogas can be processed via a Gas Clean Up System to extract a “clean” stream of methane that is the chemical equivalent to fossil natural gas. Once the gas is in this state, it is now able to be injected into the natural gas pipeline, transported as part of a virtual pipeline or used in a vehicle fueling stations for those vehicles equipped to run on natural gas.
Functions in Upgrading Biogas to Pipeline or Transport Fuel Quality (Biomethane):
Blower and water removal
Gas desulphurization
Feed/Process gas compressor
Filtration and treatment
Membrane gas separation
Desiccant dryer and/or buffer vessel
Sale gas compressors
Key instrumentation
Inlet gas flow rate and measurement
Intermediate process gas flow measurement
Product gas flow rate
Control system capable of managing & off-site monitoring of the RNG upgrading system
anaerobic digester

Biogas can be processed extracting a clean stream of methane chemically equivalent to fossil natural gas & referred to as renewable green gas called Bio-Methane or RNG.

The DMT upgrading process technology is manufactured in a local Canadian factory, and site delivered in skids to minimize on site fabrication and speed delivery. The biogas flow is upgraded through removal of Hydrogen Sulphide (H2S), water (H2O), unwanted elements and membrane separation of methane (CH4) & Carbon Dioxide (CO2) resulting in a pipeline quality methane stream (98.5%) pure (RNG) ready for injection into utility pipelines directly or virtually. RNG can be used to supply transport fuels, heat homes & businesses, or produce electricity for utilities to supply commercial/industrial energy consumers wishing to meet their carbon reduction goals. RNG injected into utility pipelines can be stored for later use and/or transported throughout North America via existing secure pipelines to fulfill energy contracts at distant locations.

RGE commissioned Canada’s first on-farm digester in B.C. for DMT with contracted gas sales to Fortis BC. Later, RGE installed Ontario’s first on-farm RNG project at Stanton Dairy Farm near Ilderton, ON, winning Canadian Bio-Gas Association project of the year (2021) award. Stanton Farm has been injecting 130,000 GJ annually into the Enbridge pipeline since Nov. 2021 to fulfill a 20-year supply contract with Fortis BC.
