- Intermittent emissions
- Downstream polishing
- Backup treatment for existing systems
Treatment equipment
CARBON
Activated carbon adsorption — Conventional VOC adsorption, downstream polishing or backup protection under suitable operating conditions.
Operating limits
Humidity, oil mist, dust and competitive adsorption can shorten service life. Assess pressure drop, outlet monitoring, media replacement and waste disposal costs together.
System combinations
Usually installed after adequate mist removal and pretreatment. It does not replace assessment of sources, capture systems and pollutant composition.
PROCESS & OPERATION
From adsorption capacity to a manageable service cycle.
ACU activated-carbon units use porous media to capture suitable compounds. Contact conditions, inlet pretreatment, temperature, pressure drop and spent-media maintenance are considered together.

- 01
Condition the inlet
Select pretreatment for particles, oil mist and humidity.
- 02
Adsorb compounds
Choose carbon type, loading, bed depth and contact time for the compounds.
- 03
Monitor operation
Track pressure drop, temperature and inlet/outlet readings for faults or breakthrough.
- 04
Replace and service
Replace media based on monitoring and arrange appropriate spent-carbon handling.
Suitable conditions
Evaluate low-concentration, relatively dry or intermittent streams; adsorption behavior varies by compound.
Operating boundaries
Humidity, oil mist, particles and competitive adsorption can shorten service intervals.
Lifecycle costs
Assess media, electricity, replacement labor and spent-carbon disposal alongside initial investment.
