Sorbent Analysis

Sorbents are widely used in the power industry to remove pollutants and potential corrosive or otherwise destructive halides, sulfides, metallic compounds, tars, organics, nitrogen compounds, or other harmful species from the exhaust or process gas. Southern Research can completely evaluate any and all sorbent types for any purpose, both in terms of chemical activity, reactivity, selectivity, and utilization, and in terms of its complete physical characteristics.

For example, Southern Research has conducted a significant volume of work evaluating and characterizing sorbents designed for scavenging:

  • HCN
  • SO2
  • SO3
  • H2SO4
  • Hg
  • HgCl2
  • HCl
  • NH3 (and other nitrogen compounds)
  • trace metals (i.e., Pb, Cd, As, Se, Ni, and their derivatives)
  • tars and other organics
  • H2S

These evaluations may be performed at temperatures and pressures as low as atmospheric conditions or they may be performed at temperatures and pressures as high as 2000°F and 400 psig.

In addition to reaction, adsorption, desorption, utilization, and deactivation characterization, Southern Research can also completely characterize the chemical and physical properties of sorbents, including:

  • density
  • surface area
  • chemical structure
  • chemical composition
  • surface speciation
  • attrition resistance
  • particle size distribution
  • grindability
