Recently, β-ETA RING® (BETA RING™) High PerformanceRandom Packing was introduced, providing further improvementover the CMR packing. The strategic, patented size and place-ment of the slots and tabs provide an extremely effective useof packing surface area. The variation in the length of theinternal tabs ensures high efficiency and optimal distribution.The result is uninterrupted flows of gas and liquid while pro-viding additional drip points to enhance liquid film surfacerenewal for improved mass and heat transfer. Consequently β-ETA RING random packing is particularly well suited forapplications where low pressure drop and high liquid handlingcapacity is important.

β-ETA RING and CMR packings have become the standardpackings for several proprietary processes and represent themajority of operational experience in many processes.
