Wet FGD and SCR in small scale

• Lowest operating cost – as expected

• Comparative investment cost – against

common expectations

• Lowest life cycle cost

• Benefits of SCR/wet FGD combination:

ammonia slip and mercury removal

• Benefits of technology flexibility: potential to

utilize waste from semi-dry FGD as reagent

Lowest cost of compliance

CIECH Soda Polska selected Valmet’s FGD and SCR

High performance expectations were met in a record

project time schedule. This project shows that thinking

‘out of the box’ while selecting the technical solution for

meeting new emission targets is important.
