Activated Alumina Bulk — Gas drying

Description

1. Product Overview

This product is a high-porosity, sphere-shaped activated alumina engineered specifically for the adsorptive drying of compressed air and industrial gases. Its primary application is in regenerative dryers to prevent hydrate formation, corrosion, and freeze-ups. The key value proposition is achieving ultra-low dew points (-60°C to -80°C) with lower regeneration energy costs. Strategically, it reduces downtime and replacement frequency, directly improving plant uptime and total cost of ownership — a critical factor in global gas processing markets.

2. Key Specifications & Technical Characteristics

• Chemical composition: Al₂O₃ ≥ 93%, Na₂O ≤ 0.4%, Fe₂O₃ ≤ 0.05%

• Purity grade: Industrial desiccant grade, high-activity formulation

• Physical form: White, low-dust spheres

• Particle size: 3–5 mm, 5–8 mm (standard); 2–4 mm also available

• Bulk density: 720–800 kg/m³

• Surface area: ≥ 300 m²/g

• Crush strength: ≥ 140 N per sphere (5–8 mm)

• Water adsorption capacity: ≥ 18% by weight at 60% RH, 25°C

• Packaging options: 25 kg moisture-barrier bags; 500–1,000 kg jumbo bags; bulk pneumatic trailers

• Shelf life: 5 years when stored in sealed, dry conditions away from acids or alkalines

3. Core Industrial Applications

• Primary industries: Petrochemical refining, natural gas processing, air separation units (ASUs), compressed air drying, landfill gas treatment

• Operational use cases: Upstream natural gas dehydration to meet pipeline dew point spec; regeneration of instrument air dryers; pre-drying before PSA or membrane units

• Performance advantage: Higher crush strength means less dusting and channeling vs. silica gel or molecular sieves in high-velocity gas streams. Superior resistance to liquid water shock reduces premature cracking. Cost efficiency: requires less frequent thermal regeneration cycles, lowering OPEX by 15–25% compared to low-grade alternatives.
