Structured PackingBed limiters are recommended for use with structured packing when there is the potential for packing displacement during upset conditions. Many columns with structured packing do not need bed limiters.
Random PackingFor metal and plastic random packings, bed limiters are recommended when there is the potential for sufficient vapor load to fluidize the top of the bed. There are three basic ways to prevent upward movement of random packing: bed limiters, anti-migration bars and hold-down plates.
Non-Interfering Bed Limiter for Structured Packing
The Model BLS-133 is used on top of structured packing to prevent movement caused by minor vapor surges. Its design minimizes interference with liquid distribution.
Non-Interfering Bed Limiter for Random Packing
The Model BLR-103 bed limiter rests on the packing and prevents random packing from escaping. It is designed to minimize interference with liquid distribution. The bed limiter diameter is expandable to permit contact with the tower wall, which eliminates the need for wall attachments.
Bed Limiter for Random Packing
The Model BLR-823 is used on top of random packing to keep the packing from moving in the tower. Packing movement can be caused by a vapor surge or fluidizing of the bed.
