This is a typical liquid distributor designed to provide excellent water distribution over a wide turn down ratio.
This is a typical liquid distributor designed to provide excellent water distribution over a wide turn down ratio. Note the multiple risers, orifices and drip tubes assuring gas and liquid separation hence minimum pressure drop: .25" WC or less.
Construction permits installation through manway of specified dimension (normally 24"). Hardware, leveling clamps and gasketing included.
Proper distribution of the liquid onto the packed bed or structured packing is accomplished by the appropriate liquid distributors. It is important to distribute the liquid flow equally across the column area in order to secure an intensive mass transfer between the phases. An important design criteria is the irrigation density; the number of drips points in relation to the column area.
In addition to the task of regular liquid distribution, the component has to meet the following requirements:
Low pressure drop in the gas phase
Resistance against dirt or solids in the liquid
High turn down ratio
Low droplet entrainment
Prevention of irregular gas distribution
Prevention of wall effect on liquid flow
The following types of liquid distributors are available:
Spray Nozzle-type Distributor
The following principles of liquid distribution are used:
By orifices at the bottom of the distribution troughs or by drip tubes perforated at the sides
Overflow distribution by slots at the side of the troughs or by overflow spouts
Each of the types and principles listed above has its specific advantages and disadvantages. We will be glad to assist you with our experience to find the appropriate type for your requirements (with regard to column diameter, liquid load, operation range, etc.)
