Acid Mist ProblemsAcid Mist Problems

2040-0102040-010

• Mists are very corrosive, viscous, clogging

• Difficult to remove; slow to coalesce into sizeable droplets when cooled

• Special coalescing filters helpful


Ammonia Salts ProblemsAmmonia Salts Problems

2040-0112040-011

Present special problemsPresent special problems

• Ammonia is gas, passes through probe filter

• Forms clogs if allowed to cool, react withSO2 or SO3 and H2O to form ammonium salts

• Requires special absorbents to remove ammonia before cooling to prevent clogs


Excessive ParticulatesExcessive Particulates

2040-0122040-012

Easiest to solveEasiest to solve

• Probe filter with heated blowback

• Secondary filter with finer porosity

• Inertial bypass filters if necessary


The SolutionThe Solution

2040-0132040-013

• Retain water-soluble analytes (HCl, SO2, NOX)

• Achieve low final sample dew points (down to -25oC)

• Accept high sample flow rates (up to 25 L/minute)

• Accommodate nearly any sample (customized)

NAFIONNAFION Selectivity Selectivity

2040-0332040-033

• Nafion permeation selectivity is based onchemical reactivity, not size

• Only compounds that chemically associate with

sulfonic acid permeate through Nafion

• Bases associate with sulfonic acid and permeate

through Nafion

• Very few bases are gases at typical operatingtemperatures, so very few compounds permeate


2040-0342040-034

Effect on AnalytesEffect on Analytes

• Removes water directly as water vapor.No condensate forms to dissolve analytes.

• Removes compounds with hydroxyl groups (-OH)

H2O, some organics

• Retains important compounds O2, O3, CO, CO2, NOX, SO2, SO3, H2S, Hg, HCl
