JACK, a dryer customer from Russia, contacted us and asked us to recommend suitable activated alumina for their dryer based on their operating environment.
The following are the operating environment data:
Will be used in compressors dryers To absorb humidity from compressed air in compressors group.
Unite operation specification:
Combined capacity 6000 +/-5% m3/h
Operating pressure 7bar
Design pressure 8bar
Inlet temperature 38℃
Outlet temperature 45℃
Regeneration circuit temperature 250℃
Drying cycle time 8 hours
We carefully reviewed the operating environment data provided by JACK and, based on this, recommend using Zibo Xiangrun XR101 activated alumina as the adsorbent.
The following are the data for Zibo Xiangrun XR101:
Activated alumina technical specification：
Form SPHERE(BALLS)
Size 5 to 8 mm
Bulk density 750 to 850 kg/m3
Surface area 320 to 360 m3/gram
Pore volume 0.4 to 0.5 cm3/gram
Absorption capacity 22% wt at least at 58% rh
Abrasion loss 0.2% at most
Crush strength 50lb (14 kg s) at least
Zibo Xiangrun's XR101 activated alumina can withstand at least 10 bar and operates smoothly at 7 bar. The customer's dryer's regeneration circuit temperature reaches as high as 250°C, and the drying cycle is 8 hours. This means the desiccant is subject to frequent heating and cooling, resulting in significant thermal and mechanical stress. XR101's compressive strength exceeding 50 lbs and its extremely low attrition rate (≤0.2%) ensures it resists pulverization during long-term cyclic use, effectively reducing pressure drop and equipment clogging, extending service life, and lowering maintenance costs. Furthermore, XR101 boasts a specific surface area of ≥320 m²/g and an adsorption capacity of ≥22% (at 58% relative humidity). This ensures efficient and deep dehumidification of compressed air within an 8-hour adsorption cycle, ensuring a stable outlet dew point.
Based on this, we believe Zibo Xiangrun's XR101 activated alumina is the ideal choice for this 6,000 m³/h compressed air dryer project. It provides efficient, stable, and long-lasting drying performance for dryer equipment.
