SO3 Sorbent Traps

SO3 Sorbent Traps


These sorbent traps capture both SO3 and H2SO4 and are especially useful for SCR engineering purposes, although they can be sampled anywhere from economizer outlet to stack. Analysis is done using ion chromatography.


SOSorbent Trap Applications

  • Measuring SO3 upstream and downstream of the SCR in order to determine conversion rate of SO2 to SO3
  • Used in conjunction with mercury oxidation studies around the SCR
