Gas treatment for IGCC Plant

Integrated coal Gasification Combined Cycle (IGCC) is a new power generation system aiming at higher efficiency than the conventional coal-fired systems by integrating coal gasification with combined cycle(C/C) power generation technology. In Japan, the development of original IGCC technology has been pushed forwarded as a national project.

4.The Role Of Gas Treatment Process

  • 1)Treatment Gas Condition
    -To-S(H2S+COS) : <50ppm
    -> Environmental Regulation
    -NH3: <10ppm
    -> Environmental Regulation
    (Measure Of Fuel NOx)
    -Removal of Alkaline metal(Na,K),
    Very-small-quantity ingredient(Cl,F,Zn,Pb,V,Hg,Se,B,Ca,etc.)
    -> GT Fuel Regulation,
    Prevent of Amine Degradation
  • 2)Prevent of Plant Thermal Efficiency Lowering
    -Heat Recovery

    -Min. Steam Consumption
    ->Gas Cooling For Process Requirement(Amine Process)
    ->Fuel Gas Temperature Makes High As Much As Possible.
