Different operating conditions require different performance characteristics from activated alumina. Inappropriate selection of the appropriate type can lead to decreased adsorption efficiency, increased pressure drop, pulverization and breakage, and even equipment instability. So, how should companies select the right activated alumina type based on their specific operating conditions?
I. First, clarify the operating requirements
Before selecting an activated alumina desiccant, it is essential to understand the following parameters:
1. Treatment medium
Different media have different requirements for the adsorbent. For example:
· Compressed air drying
· PSA oxygen/nitrogen production
· Natural gas dehydration
· Liquefied petroleum gas drying
· Hydrogen purification
· Chemical tail gas treatment
Some gases may contain oil mist, acidic gases, or impurities, placing higher demands on the anti-pollution capabilities of activated alumina.
II. Focus on Core Performance Indicators
1. Adsorption Capacity
Adsorption capacity determines the water absorption capacity and service life of activated alumina.
Generally speaking:
· High humidity conditions → Require high adsorption capacity models
· Deep dehydration → Require low dew point models
· High-frequency regeneration → Require products with stronger thermal stability
For systems with lower dew point requirements, it is recommended to choose high-performance activated alumina with a more developed microporous structure.
2. Compressive Strength
In large adsorption towers or high-flow-rate systems, activated alumina is subjected to long-term airflow impact and bed pressure.
Insufficient strength can easily lead to:
· Pulverization
· Crushing
· Increased pressure drop
· Pipeline blockage
Therefore, high-strength, low-wear models should be prioritized for high-pressure, high-flow-rate conditions.
