2.10.4: Horizontal Separator with a “Boot” or “Water Pot”
A single barrel separator with a liquid “boot” or “water pot” at the outlet end is a special case of a two-barrel separator (Figure 2-12). It is. The main body of the separator operates essentially dry as in a two-barrel separator. The small amounts of liquid in the bottom flow to the boot end, which provides the liquid collection section. These vessels are less expensive than two-barrel separators, but they also contain less liquid handling capability. It is used when there are very low liquid flow rates.

In applications where there is very little liquid flow, often a horizontal separator will be designed with a liquid sump on the outlet end to provide the required liquid retention time. This results in an overall smaller diameter for the vessel.
