1x1 Discrete GBX: 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

◙ Rated Throughput The total rated mass throughput.	360,000entities/h	Positive
◙ Max Throughput The desired upper limit of the sizing variable. Used only in design mode to determine if multiple units are required.	720,000entities/h	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 Throughput and the system computes the Number of Units and the Rated Throughput. If the operating throughput exceeds the maximum throughput, then, the system assumes multiple, identical units operating in parallel with an operating throughput of less than the maximum.

Sizing: Rating Mode

In User-Defined (Rating Mode), the user specifies the Number of Units and the Rated Throughput. If the operating throughput exceeds the rated throughput of the step (which is equal to the rated throughput of each unit times the number of units), a warning message is displayed advising the user to increase the number of units or reduce the operating throughput.

Costing

No cost is calculated for this equipment, as it represents generic equipment that is not explicitly available in the current version of SuperPro Designer. The user can directly enter the cost, or a user defined model for the equipment cost.
