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
