FGD system

Semi-dry FGD is the best economical concept for industrial and utilities boilers using coal as fuel

 

It is a dry SecoLAB™ process consisting of a conditioning tower, a LABLoop™ dry reactor, a fabric filter with residues recirculation and reactivation in the humidification screw reactor.

Quick or hydrated lime may be used as reagent and on-site lime slaking can be offered as well.

The Semi-dry FGD is the perfect flue gas desulphurization concept for existing small and middle size plants to fulfill BREF conclusions from IED Directives.

Wet FGD is the most efficient process for large fossil-fuel power plant 

LAB solutions are based on long experience of GraniLab™ technologies and are providing more than 95% removal of SO2 in flue gases.

Different concepts can be offered : 

 

  • Limestone / lime spray towers including slurry preparation unit, gypsum production unit and water treatment
  • Sea water scrubbers with on-site treatment of the bleed
  • Ammoniac spray towers including evaporation unit and ammonia sulfate production (used as fertilizer)
