Selective Catalytic Reduction(SCR)

홈 Business Gas Treatment Selective Catalytic Reduction(SCR)

Selective Catalytic Reduction ( SCR )

  • Conventional De-NOx technology is to reduce NOx and then be removed by using NH3 or Urea.
  • Haecheon Industrial Co.,Ltd make engineering design by using various SCR catalysts and selecting proper catalyst according to exhaust source and kinds of gas.

SCR Reactor Type

[ Vertical type SCR Reactor ]

[ Horizontal type SCR Reactor(HRSG) ]

  • VERTICAL TYPE
    • Can be applied to SCR single system
    • Applied to gas treatment of high concentration of dust.
    • Space for installation is small.
  • HORIZONTAL TYPE
    • Can be applied when several unit processes of plant are
      combined in one unit (HRSG).
    • Can be used in gas treatment process of low concentration dust.
