Liquid Distributors
High performance liquid distributors aim towards ideal liquid distribution, i.e. equal liquid rate per unit area of the packed bed surface. These distributors are available in a wide range to suit various column diameters, liquid rates and service conditions. Models that can give turndown ratios of up to 10:1 are available. Our design team selects the most suitable model for a given application.
Bed Limiters
Bed limiters are safety devices that are available for both random as well as structured packing, to avoid the expansion of the packed bed, as well as to maintain the bed top surface level.
Support Plates
Support plates, in addition to providing physical support to random packings, must also allow unrestricted flow of gas and liquid. Gas injection support plates provide separate passageways for liquid and gas, which minimizes the pressure drop across the plate. Support plate model is selected depending upon the packing type, size and the maximum design load to be supported.
Collector/Chimney Trays
Collector trays are used to collect liquid from between packed beds. Liquid interception is required in various situations, such as total or partial draw-off of liquid or change in the column diameter, which sometimes necessitates the redistribution of the liquid to cool the liquid in absorbers before passing to the next packed bed etc. Different types of collector trays are available to suit the column diameter and the vapour and liquid rates.
