Comparison of performance parameters between ceramic pall ring and plastic pall ring

Comparison of performance parameters between ceramic pall ring and plastic pall ring

Parameters	Ceramic pall ring	Plastic pall ring (φ50mm)
Specific surface area	70-210m²/m³ (the smaller the size, the larger the specific surface area)	93-300m²/m³ (φ25mm can reach 300m²/m³)
Porosity	68%-81%	85%-95% (lower fluid resistance)
Pressure drop	φ50mm specification pressure drop is about 30-40mmH₂O	φ50mm specification pressure drop is about 30-40mmH₂O (similar to ceramic)
Mass transfer efficiency	50%-100% higher than Raschig Ring	50%-100% higher than Raschig ring, with large operating flexibility
Number of stacking	6500-53500 pieces/m³ (the larger the size, the smaller the number)	6300-180000 pieces/m³ (φ25mm has the highest density)
