Ceramic Pall Ring For CO2 Absorption
An upgrade to the ceramic Raschig Ring design, Ceramic Pall Ring feature a cylindrical shape with open walls and inward-bent tabs. This design maximizes surface area while minimizing the number of contours, allowing gases and liquid to flow freely while greatly reducing the potential for entrainment.
Ceramic pall ring offer good mechanical strength as well as a nonporous surface. Ceramic is inert and iron-free, as a result, won't rust or react when used with harsh chemicals. |
