The president of Sysgaz , Charles Tremblay, said that the company is planning to implement renewable liquefied natural gas production plants in Saguenay-Lac-Saint-Jean, Trois-Rivières and Québec regions.
These liquefaction plants will form the Saguenay-Lac-Saint-Jean Regional Corridor, 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, according to the Sysgaz statement.
The SLRC will include six liquefaction plants with a production capacity of approximately 75 tons per day, 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.
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-LNGproduced from landfill gas will generate 80% less greenhouse gasses 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.
Sysgaz developed a new technology called the R-LNG Process enabling the creation of the SLRC. 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 first SLRC plant will be a pilot plant with a production capacity of 1 TPD (1 300 diesel liters equivalent per day). The Dolbeau-Mistassini plant will be a model for future liquefaction plants to be implemented along the SLRC. According to Sysgaz, the R-LNG production is scheduled for summer 2016.
