Continuous Stoichiometric Reaction/Separation in a GBX

General Description

This is a multi-task operation which can be used to simulate continuous stoichiometric reaction (in a GBX) followed by flow or component splitting. You can choose to perform reaction calculations and or separation calculations. If you don’t select any of these calculations then the operation acts as a pass through operation. (The separation option is not available in the 1x1 Continuous Generic Box Reaction (Bulk) Procedure.

Continuous Stoichiometric Reaction/Separation in a GBX: Modeling Calculations

Reaction Calculations

The feed flowrate is calculated by adding the feed flowrates of all input streams The reaction operation can handle any number of sequential material transformations (reactions) that happen continuously in generic equipment and for which kinetic expressions are unknown or unimportant. For more details click on the material balances tab.

The operating throughput (per unit) is calculated by dividing the feed flowrate by the number of units.

Separation Calculations

You can choose either component or flow splitting. The splitting is performed after the reactions. You can specify either the component splits (% flows) or the total flow split, and whether this specification refers to the top or bottom splits. If the component split option is chosen the flowrates of each component is split into the 2 output streams according to the specified split for each component. If the total flow option is chosen the total flow rate is split into the 2 output streams according to the total flow specification.

Equipment Sizing

If the equipment size option is in Design Mode and the operating throughput exceeds the maximum throughput, then, the program assumes multiple, identical units operating in parallel with an operating throughput of less than the maximum. If the equipment size option is in Rating Mode and 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.

Duration

If the duration of this operation is matched up to another operation (master operation), then the setup time, process time and turnaround time are simply derived from the master operation. For more on master-slave relationships, see The Scheduling Tab.
