A power plant in Poland used a semi-dry process to remove acid gases. But stronger regulations on acid gas emissions, particularly SO2, mandated emission levels below 400 mg/Nm3. Management recognized that the efficiency of the plant’s flue gas treatment (FGT) process needed to be significantly improved.
Looking for a cost-effective total solution, they considered investing in a wet FGT process.
The Lhoist solution included the following elements:
The solution enabled the power plant to conform to the required emission levels without expensive investment in new wet FGT process equipment. The existing facilities were improved both in terms of reliability and efficiency.
The refurbishment primarily consisted of:
