Gas processing contract in Stockholm awarded to Schmack Carbotech

ADBA member news

Biogas fuel for 5000 Swedish cars.

Schmack Carbotech has been awarded the contract to construct a plant with a processing capacity of 2000 Nm³/h in raw biogas in Sofielund Huddinge, Stockholm. Gas with a methane content of 97 percent after purification will be produced for use as a biofuel in vehicles powered by natural gas. The acceptance of and demand for environmentally friendly technologies are very high in Sweden: Forty percent of newly licensed cars are operated either with biogas or electricity. The biofuel is renewable and has an even CO2 balance.

The processing plant uses the pressure swing adsorption (PSA) principle. This leading process distinguishes itself with low energy consumption, efficient heat extraction and a high methane yield. Trace gases that are typically found in biogas made from waste water and organic waste are effectively removed as well.

After completion, the plant will produce biogas with an energy yield of nearly 100 million kilowatt hours annually This means it can supply approximately 5000 vehicles travelling an average of 20,000 km per year. The city of Stockholm is therefore increasing its proportion of bio-methane to 50 percent starting in 2015.

Organic waste and fryer grease from the region will be used as raw material for the plant.

Supply capacity: up to 1410 Nm³/h bio-methane. The plant is expected to be completed and put into operation in the first quarter of 2015.
