We Attaquant Design and Manufacture Bed Limiters for all types of Distillation Columns. We manufacture in following MOC SS 316L, SS 304, Monel, Inconel, Hastelloy, Titanium, Zirconium etc.
Bed limiters are designed so that they do not disturb the steady-state of the liquid distribution. Depending on the model, bed limiters either sit directly on the top of the packed bed or are mechanically attached to the vessel wall. It is also possible to hang them directly from the liquid distributor or re-distributor. They usually provide high open-area and reduce interference to liquid flow.
This bed limiter is normally recommended for towers using structured packings. Fluidization does not occur with structured packings, but for large diameter columns, sections of packings may be dislodged during upset conditions. Bed limiters for structured packings are designed to reduce interference with liquid distribution.
