Air Purification System Evaluation

Purpose

• To determine the corrosive potential of an instrumentation,
  electrical or control room
• To quantify corrosive potential in accordance with ISA air quality guidelines
• To evaluate the operation of an existing controlled environment in terms of corrosive potential

Procedure

• Perform an in depth analysis of existing gas scrubbing, HVAC
  and humidification equipment
• Measure system air volumes, temperatures, relative humidity
  and space pressurization
• Determine corrosive contaminant species and estimated severity by investigative and analytical means
• Perform corrosion coupon testing using copper and silver strip
  cathodic reduction analysis
• Determine purification media life remaining and confirm suitability to application

Report

• Provide a written report summarizing air quality issues and
  quantifying environment in terms of ISA guidelines
• Provide specific recommendations for equipment modifications
  and upgrades to ensure an ISA G-1 environment
