DeSOx Systems

Wet Limestone Based Flue Gas Desulphurization System (WFGD)

Isgec is having Collaboration and Technology Transfer Agreement with Babcock Power Environmental Inc. (BPE), USA for Wet FGD Systems for Coal fired Boilers of Unit size more than 100MWe. BPE is an industry leader in the design and manufacturing of Wet Flue Gas Desulphurization systems and equipment. BPE has been providing environmental solutions since over four decades & have strong references of more than 66GW in FGD units for variety of fuels including lignite, low/high sulfur coals.

Salient Features of Wet Limestone based FGD:

  • SO2 removal efficiency >99%
  • Utilises Limestone as Reagent
  • High turndown ratio
  • High reliability and less power consumption as per BPE Design
  • High operational flexibility
  • Saleable byproduct
  • Lower L/G ratio 

Dry Sorbent Injection System (DSI)

Isgec is having Collaboration and Licensing Agreement with United Conveyor Corporation (UCC), USA for Dry Sorbent Injection Systems on case-to-case basis.

UCC is a pioneer in Dry Sorbent Injection Technology which injects selected sorbents into the flue gas for SOx reduction in coal fired Power Plants. UCC has been providing environmental solutions since two decades and have strong references of more than 100 installations worldwide.

Salient Features of Dry Sorbent Injection:

  • Dry Sorbent Injection
  • SO2 removal efficiency upto 70%
  • Utilises Sodium Bicarbonate as reagent
  • Low Capex
  • No water usage hence no waste generation
  • Very Low Power Consumption
  • High operational flexibility
  • Fully automated and hands-free operation
  • Minimum downtime for installation
  • Multiple location reagent injection results in better sorbent distribution
