Plastic Ralu Ring With PP / PE/CPVC

The plastic Ralu ring is an improved Pall ring whose open structure ensures regular flow through the packed bed, thereby minimizing pressure drop.

The plastic Lalu ring has the characteristics of large free volume, low pressure, low mass transfer unit height, high flooding point, uniform gas-liquid contact, low specific gravity, high mass transfer efficiency, etc., and it is suitable for the temperature of the medium from 60°C to 280°C .

Plastic Lalu ring is suitable for various separation, absorption, desorption devices, atmospheric and vacuum devices, synthetic amine decarburization, desulfurization systems, ethylbenzene separation, isooctane, toluene separation, etc.
