Liquid Distributors

Key Characteristics

• Liquid loads of 0.02m3/m2h to greater than 300 m3/ m2h
• Number of drip points: 150-200 /m2 depending on the application and liquid load
• Standard turndown ratios to the order of 1:25
• Standard turndown rations to the order of 1:10 is possible using multi-stage distributors

Liquid Distributor Configurations

Channel Type Distributor

• Normally used in column diameter up to 1.5m and flow rates in the range of 1-35 m3/m2h
• Liquid is fed into a large central channel and then distributed through the holes in the individual channel onto the packing

VEP Distributor

• Normally used in large diameter columns with flow rates in the range of 1-35 m3/m2h
• Feed liquid is pre-distributed at a controlled rate from main channel to individual arm channel
• Larger hole diameters than conventional discharge systems

Trough type Distributor

• Normally used when column diameter is less than 1m
• Similar to channel type distributor
• Liquid first flows into the main channel & then to the individual arm channel.
• Surface area coverage is high for the distributor

Pipe Type Distributor

• These distributors are generally used when the requirement is for a distributor which is non sensitive on moving conditions like offshore columns of vessels
• The Liquid discharge takes place from the underside of distributor tubes
• Not suitable for liquids with solid contaminants

Pan Type Distributor

• Normally used in columns with diameters upto 1.2m & flow rates in the range of 2.5 – 75 m3/m2h
• Orifices for Liquid flow are provided in the bottom of the Pan
• Vapour passage is provided by circular or rectangular gas risers
