Oil Separator: Equipment Tab

Variable Definitions, Ranges and Default Values

The following table shows the meaning of the variables appearing in this tab, as well as their default values and their generally acceptable range. Note that due to the manner by which the variables are used by the sizing and costing equations, the range of acceptable values may be further reduced.

Variable	Default Value	Range

◙ Max Horizontal Area The maximum surface area that a unit of this type is available for purchase in the market.	2500.0 m²or 5000.0 m²	Positive
◙ Length The length of the tank.	0.0 m	Positive
◙ Width The width of the tank.	0.0 m	Positive
○ Depth The depth of the tank.	2.0 m	Positive
● Horizontal Area The horizontal area of the tank.	0.0 m²	Positive
● Vertical Area The vertical area of the tank.	0.0 m²	Positive
● Volume The total volume of the tank.	0.0 L	Positive

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Sizing: Design Mode

In Calculate (Design Mode), the user specifies the Maximum Horizontal Area and the system computes the Number of Units, Length and Width. the tank depth is always specified. For more information on sizing of a oil separator, see Oil Separation: Modeling Calculations.

Sizing: Rating Mode

In User-Defined (Rating Mode), the user specifies the Number of Units, Length and Width. The tank depth is always specified.

Costing

The equipment purchase cost is based on the throughput, and is calculated by the built in model for a oil separator with a minimum throughput of 20 m³/h.
