Wärtsilä has engineered, delivered, and put in the biogas upgrading resolution to a brand new biogas 17 tpd liquefaction plant in Hjørring, Denmark. The contract was awarded to Wärtsilä in 2022, and the official start-up happened in June 2023.
The power is one among two biogas vegetation owned and operated by GrønGas A/S in Denmark. The opposite plant, positioned in Vrå, additionally contains a Wärtsilä biogas upgrading resolution. The plant in Hjørring has a manufacturing capability of greater than 6200 tpy of bio-LNG. Denmark is a world chief in biomethane growth, and these vegetation are seen as being an essential factor in securing the nation’s inexperienced power future.
The Wärtsilä Blended Refrigerant (MR) liquefaction unit alone has an exceptionally low energy consumption of <0.75 kWh/kg of bio-LNG liquefied. This, together with Wärtsilä’s Puregas CA know-how for biogas upgrading and sprucing, with a complete methane lack of lower than 0.1%, makes it extraordinarily power environment friendly. The Puregas CA at Hjørring is provided with the patented VAC (vacuum) possibility that provides higher flexibility in delivering warmth to the upgrader, warmth sources right down to a temperature of 95°C are doable to make use of.
The Hjørring plant transforms manure-based biogas into bio-LNG, representing annual carbon dioxide financial savings of roughly 41 000 tpy when changing pure gasoline.
“Biogas is a renewable power supply that may be saved, and it’s of nice significance as Denmark seeks to fight the consequences of local weather change. The belief and effectivity of the Wärtsilä options chosen for our two websites is central to those efforts,” stated Allan Okay. Olesen, CEO, GrønGas.
“We at Wärtsilä are proud to contribute to a decarbonised future, and we congratulate GrønGas on the opening of this essential new plant. Their vegetation are doing an important job in lowering greenhouse gasoline emissions, and we’re happy to help them. Our biogas options are designed to benefit from power integration, which optimises their efficiency and minimises the general power prices,” added Goran Gajski, Gross sales Supervisor Biogas, Denmark/Norway, Wärtsilä Gasoline Options.
The complete Wärtsilä scope for the Hjørring set up contains the Puregas CA biogas upgrading and sprucing unit, with the patented Wärtsilä VAC resolution, the liquefaction unit primarily based on MR know-how, a 250 m3 bio-LNG storage tank, bio-LNG export station to tank-truck, and instrument air.
