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