Plastic Pall Ring was invented by BASF in Germany. Compared with the Raschig ring, the most important improvement is the addition of two rows of inwardly curved inner tongues. This structure promotes gas-liquid fluidity and improves the mass transfer performance of the tower packing. Since then, more newly designed products will be brought, such as Hy-pak, Flexring, etc.

Applications: 
It can be applied to various of device of isolation, absorption, deadsorption, common decompression such as Toluene separation, ethylbenzene separation, isooctane separation and desulfurization system etc.
