Sysgaz, Inc., a Canadian manufacturer of small scale liquefaction plants, recently presented an update of its project first introduced in July 2015. At that time Sysgaz advised plans to implement renewable liquefied natural gas (R-LNG) production plants in Saguenay-Lac-Saint-Jean, Trois-Rivières and Québec regions, forming a R-LNG Saguenay-Lac-Saint-Jean Regional Corridor (SLRC). The first step, construction of a pilot plant at Dolbeau-Mistassini in Northern Quebec, is planned for this year.
Mr Charles Tremblay, President of Sysgaz, explained to NGV Global News: “Currently, there is no complete liquefaction plant that is running. However, the landfill gas production system designed and integrated to be used with liquefaction plants in fully operational and has “cruise control” running for the last 4 years on a conventional landfill gas project. R-LNG production is planned for December 2016.”
At completion of the project, the SLRC will include six liquefaction plants with a production capacity of approximately 75 tons per day (TPD), or 100 000 diesel liters equivalent per day. The construction of the liquefaction plants and refueling infrastructures will take place over a 4 year period and will require an investment of $85 million.
“Sysgaz has designed and integrated all systems and equipment related to the LNG process for our three (3) models of small-scale liquefaction plants (10, 15, 20 tpd)”, Tremblay said. “Sysgaz is also manufacturing, installing and operating the plants.”
The plants will liquefy both natural gas and landfill gas (renewable natural gas – RNG) to ensure security of supply to customers, facilitate project implementation and increase the liquefaction plant production capacity. Tremblay added: “The North american averaged landfill site yield is evaluated at 8 – 10 tpd (with 100% landfill gas). By adding some natural gas we can significally increase plant capacities.”
Tremblay says there are companies in the region currently upgrading fleet vehicles to LNG, but uptake has been slow in the face of high costs to set up LNG fueling infrastructure. He believes the Sysgaz system enables that infrastructure to be delivered more economically, with “one manufacturer delivering one product – one plant – one station”; thereafter, he expects LNG fuel demand will grow significantly.
At launch last year, the company stated the purpose of the SLRC was to offer an affordable and low-polluting fuel alternative for industrial and trucking companies of the Saguenay-Lac-St-Jean region. The liquefied fuel will be 25% cheaper than diesel and the R-LNG produced from landfill gas will generate 80% less greenhouse gases than diesel.
The Dolbeau-Mistassini Liquefaction Pilot Plant will have a production capacity of 1 TPD (1 300 diesel liters equivalent per day). This plant will reportedly be the first facility of its kind in Canada and will produce R-LNG. The Dolbeau-Mistassini plant will be a model for future liquefaction plants to be implemented along the SLRC.
At term, the SLRC will be connected to the Gaz Métro Blue Route, which will allow SLRC plants to connect to the LNG networks of North America.
