scope:

The purpose of this monograph is to provide design guid- ance on gravity-type oil-water separators for use in petro- leum refineries, to provide practical advice on solving operating problems and improving separator performance, and to present information on the performance of existing separators.

This monograph deals solely with gravity-type oil-water separators, that is, those that rely on differences in specific gravity to separate oil globules from a wastewater stream. Two types of oil-water separators are covered in this mono- graph:

a. The conventional, rectangular-channel unit.

b. The parallel-plate separator.
