A consortium consisting of Primetals Technologies Austria GmbH and YARA Environmental Technologies GmbH, both based in Austria, has been awarded by Acciaierie d’Italia a contract for a new flue-gas treating systems for the three 160 MW boilers at its power plant No 2 in Taranto in Italy. Within this consortium, Yara will deliver the new economizer and selective catalytic reduction DeNOx elements and Primetals Technologies will cover the DeSOx- and dedusting part. The startup of the first FGT unit is scheduled for the fourth quarter of 2022 with the other two units following in short succession.The high temperature of the flue gas coming from the boilers will be utilized for the SCR DeNOx process which requires temperatures of more than 300 degre Celsius. The SCR catalyst will be integrated into the boiler economizer. Due to its condition, the existing, original economizer will be replaced by a new state-of-the-art version. SOX in the flue gas will be controlled by applying Primetals Technologies’ proprietary Meros technology. Based on the favorable process conditions and the limited available space, sodium bicarbonate (SBC) will be used as DeSOx agent which ensures high DeSOx efficiency but does not require any water injection as it is a completely dry technology. This technology has been invented by Primetals Technologies and has already been successfully applied in numerous plants.The FGT systems will also be designed to cover all the changing load- and flue gas conditions of power plant No 2. As the boilers are fired with the typical by-product gases from steel mill operation (coke oven-, blast furnace- and converter gas) the quantity and mix of those gases may vary depending on their availability and the FGT system will cover all those different load cases accordingly while still maintaining the required environmental performance.Built in the early 1970s, power plant CET 2 is a conventional thermo-electric power plant which will now undergo a major environmental upgrade through the installation of state-of-the-art flue gas treatment technologies, including SCR DeNOx system (integrated in a new economizer) for reduction of NOx emissions by 80%, Meros DeSOx technology for reduction of SOx emissions to less than 130 mg per cubic meter and high-end fabric filters for removal of fine dust emission to less than 2 mg per cubic meter.
