Q1: Why must activated alumina be used in air separation equipment?
A: In air separation systems, if moisture in the air directly enters the molecular sieve, it can cause the sieve to become damp, poisoned, or even malfunction. Activated alumina, as the first adsorbent in the pretreatment process, can effectively intercept moisture and impurities, protecting the molecular sieve and extending its service life.
Q2: What is the difference between activated alumina used in air separation equipment and ordinary activated alumina used for drying?
A: Air separation equipment operates at high pressures, has long continuous operating times, and requires frequent regeneration, placing higher demands on the strength and stability of the adsorbent. Activated alumina specifically designed for air separation has higher compressive strength, lower wear rate, and a more stable pore structure.
Q3: What are the commonly used activated alumina particle sizes for air separation equipment?
A: Common particle sizes are 3–5 mm, 4–6 mm, and 5–8 mm. The specific particle size needs to be determined based on the air separation equipment design parameters, gas flow rate, and bed structure. Zibo Xiangrun can provide customized particle size solutions based on operating conditions.
Q4: How often does activated alumina used in air separation equipment need to be replaced?
A: Under good air quality and regeneration conditions, the lifespan of activated alumina from Zibo Xiangrun Environmental Engineering Co., Ltd. is generally around 5 years.
Q5: Will activated alumina affect the adsorption efficiency of molecular sieves?
A: No. High-quality activated alumina can effectively remove moisture and impurities at the upstream end, thereby reducing the load on the molecular sieve, extending its service life, and improving overall adsorption efficiency.
Q6: How to determine if the activated alumina in an air separation unit is nearing failure?
A: When there is a continuous increase in the outlet dew point, abnormal system pressure drop, shortened molecular sieve adsorption cycle, or insignificant recovery of adsorption capacity after regeneration, it usually indicates that the performance of the activated alumina has significantly declined and it should be inspected or replaced promptly.
Q7: Can activated alumina be customized for specific air separation projects?
A: Yes. Please send your technical parameters to our technical staff.
Q8: What factors should be prioritized when selecting an activated alumina supplier?
A: It is recommended to focus on the product's mechanical strength, wear rate, application cases, technical support capabilities, and supply stability, rather than just price.
Q9: Why choose Zibo Xiangrun's activated alumina for air separation equipment?
