Convergen Energy instala un sistema de inyección de adsorbente en seco permanente
New system installed at Convergen's Michigan biomass power plant
Convergen Energy is embarking on installation of a permanent dry sorbent injection system (DSI) at its L'Anse Warden 20 Megawatt biomass power plant located on the shore of Lake Superior in the Upper Peninsula of Michigan.
The DSI forms part of the plant's air pollution control technology and is used to scrub acid gases from the exhaust stack of a solid fuel boiler. The permanent system will enable Convergen to comply with its air permit emissions limits and replaces the previous temporary system.
The DSI system injects calcium or sodium based reagents that contact the acid gas particles in the boiler’s exhaust gases and converts them to a solid particle that is removed in a baghouse or electrostatic precipitator (ESP). For example, HCl (gas) combines with the sodium-based reagent to form NaCl which is a solid and can be removed in a baghouse or ESP. The installation is part of Convergen’s ongoing efforts to increase operational efficiency and minimize air emissions at the plant.
Convergen Energy acquired the L’Anse Warden Electric Company (LWEC) power plant from the Traxys Power Group in November 2016. LWEC is a combined heat and power (CHP) 20 Megawatt power plant and supplies electric power to the grid for the Upper Peninsula under a power purchase agreement for renewable energy. The plant also supplies steam and electricity to the CertainTeed Plant that is adjacent to LWEC in L’Anse, MI. As such, the LWEC Plant generates both steam and electricity for sale.
In addition to its clean power interests, Convergen Energy repurposes a wide variety of industrial and agricultural by-products into burn-ready fuel pellets with lower emissions yet the same energy output as coal. It also operates a number of biogas facilities in Latvia, northern Europe.
