Specification Choices / Comments

The following list describes the available specification choices in this tab; for more details on how these are implemented, see IP Clarification: Modeling Calculations.

•Design Options...

In Design Mode, the unit can be sized to remove oil globules, solid particles, or both.

The turbulence and short circuit factor is either specified by the user or calculated by the program.
