Fiber-Bed Scrubbers

In a fiber-bed scrubbers, the moisture-laden gas stream passes through mats of packing fibers,

such as spun glass, fiberglass, and steel. The fiber mats are often also spray wetted with the scrubbing

liquid. Depending on the scrubber requirements, there may be several fiber mats and an impingement

device for PM removal included in the design. The final fiber mat is typically dry for the removal of any droplets that are still entrained in the stream. Fiber-bed scrubbers are best suited for the collection of soluble PM, i.e. PM that dissolves in the scrubber liquid, since large amounts of insoluble PM will clog the fiber mats with time. For this reason, fiber-bed scrubbers are more often used as mist eliminators, i.e., for the collection of liquids, rather than for PM control.
