Feed devices
Obtaining desirable tower performance requires the proper handling of liquid and vapor entering the column.

Model 199 high performance liquid only feed pipe
The types of feeds or inlets into a column can generally be classified into four major categories. Koch-Glitsch offers a variety of devices designed to handle each of these situations.
  • Liquid only (contains less than 1% vapor by volume)
  • Mixed liquid and vapor, flashing or suppressed flash
  • Vapor only
  • Reboiler returns


Among the factors Koch-Glitsch engineers consider in designing a liquid feed device are:

  • Type of distributor
  • Expected distributor performance
  • Liquid and vapor flow rate
  • Operating range
  • Degree of sub-cooled liquid
  • Whether mixing with overhead liquid is required
