Odor Control Wet Scrubbing System Evaluation

Purpose

• To determine the operating efficiency of an existing odor control wet scrubbing system
• To identify operating and design limitations in odor control wet
  scrubbing systems
• To provide recommendations for improving odor abatement efficiency

Procedure

• Determine gas stream volume, temperature, humidity and contaminant speciation using the appropriate analytical methodology
• Evaluate tower hydraulics, mass transfer zone design, liquid and gas mass loading, packing design
• Examine reagent feed, monitoring and control system
• Test scrubbant solution as supplied to MTZ and in solution purge
• Perform computer modeled atmospheric dispersion analysis of
  discharge stack
• Evaluate odor capture and containment system

Report

• Provide a written report identifying the tower operating efficiency on all pertinent chemical constituents
• Provide specific identification of system operating limitations, complete with recommendations for improvement
• Quantify specific odorous chemicals and approximate their relative
  contribution to odorous emissions and to perceived odors at
  receptor sites
