Plastic Random Packing

Plastic Random Packing

Listed below are the plastic random packing options offered by Raschig USA. These options are a lighter weight alternative to the original raschig ring, with different levels of chemical resistance available according to the chosen plastic resin.

These plastic packings are commonly found in environmental applications involving scrubbing and stripping of different contaminants. For example, air stripping can remove VOCs, H2S, CO2, BETX, NH3, or more from water. Similarly, Packed bed wet scrubbers can remove H2S, acid gases, SO2, amines, or more from air.
