Sysgaz Inc., a Québec company that manufactures small scale liquefaction plants, is planning to implement renewable liquefied natural gas (R-LNG) production plants in Saguenay-Lac-Saint-Jean, Trois-Rivières and Québec regions, said company president Mr. Charles Tremblay. These liquefaction plants will form the Saguenay-Lac-Saint-Jean Regional Corridor (SLRC), the first R-LNG network supplied with small scale production plants.
At term, the SLRC will be connected to Gaz Métro Blue Route, which will allow SLRC plants to connect to the LNG networks of North America.
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 (USD 67 million).
The purpose of the SLRC is 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 (biomethane or renewable LNG) produced from landfill gas will generate 80% less greenhouse gases than diesel.
The first SLRC liquefaction plant will be located in Dolbeau-Mistassini. The wellhead designed to connect the horizontal landfill gas collector was already delivered in May 2015.
“We are pleased to start implementation of the SLRC with the Dolbeau-Mistassini liquefaction plant. This project will use landfill gas from the MRC de Maria-Chapdelaine landfill site and will be the first energy production infrastructure to provide natural gas to northern Lac-Saint-Jean”, stated Mr. Tremblay.
The creation of the SLRC is made possible by a new technology called the R-LNG Process developed by Sysgaz. The process integrates landfill gas production, upgrading and liquefaction systems to transform multiple methane gas sources into R-LNG within a single production plant. The advantages of this innovation are that it can be deployed in a variety of small scale production plants (10-50 TPD) and is capable of pre-mixing multiple methane gas sources, whether from landfills, anaerobic digesters or low pressure gas networks to produce liquefied fuels.
“The possibility of using landfill gas as a raw material to produce renewable liquefied fuel has been demonstrated successfully with the l’Ascension-de-Notre-Seigneur project which has been running at full capacity since 2012. We also signed an exclusive license with our Norwegian strategic partner SINTEF for its Mini-LNG technology. To date, Sysgaz’s innovations related to the new R-LNG Process were awarded three Canadian Green Technologies Patents and one U.S. patent. The Dolbeau-Mistassini project will allow final calibration of all systems of the new R-LNG Process prior to its large scale implementation in the SLRC. With these projects, Sysgaz will be investing $10 million”, stated Mr. Tremblay.
Dolbeau-Mistassini Liquefaction Plant
The first SLRC plant will be a pilot plant with a production capacity of 1 TPD (1,300 diesel liters equivalent per day). This plant will 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, demonstrating the performance of the new R-LNG Process. R-LNG production is scheduled for summer 2016.
