3.1.5.1.1.2 Packings Geometry Estimation

DRP 4.0 Release Page 11

DRP allows the estimation of packing geometry (e.g. column diameter, bed height, etc.) for a given process condition.

To estimate packing geometry, first select a Process ID and a Model ID from the dropdown lists. Next, set criteria for either allowable dynamic pressure drop, or flood percentage, then set criteria by specifying the bed height or allowing the tool to find bed height using a number of theoretical stages. Finally, the user can enter packing values or choose preconfigured values for the specifications available by displaying the packings dialog by

clicking on the

button in the Packing Name field.

Beginning with DRP 3.6, support for 4th generation random packings has been added. When working with 4th generation packings, the selected model must use TR-208 or TR209 correlations. For earlier packings, TR-208 and TR-209 are not applicable and you should choose other correlations as appropriate. If the packings and correlations are not compatible, you will see the Calculate button change to “Model ID” in red color and appear

as

. If you click on the Model ID button, it will display a message indicating

that the packings selected is not compatible with the selected model / correlations.

The Create Device button will create a new Packing Hardware Device with the estimated parameters. The hardware device can then be used in an output case for rating calculations. The Packing Geometry Estimation form appears below.

study, or a model ID. .

Label

Identifier (Process, Hardware, Output

Case)

Process

Process form label

ID

Device Rating Program User’s Manual Version 4.0
Hardware ID Model ID

Hardware form label

DRP 4.0 Release Page 16

Set of Correlations to Apply

If the user does not specify a Label, one will be generated using a tab- specific template. The default model will be selected for the Model ID. Each ID cell in the output cases is a combo box that acts as both a typical text entry box and a drop-down box. Pressing the down arrow to the right of the cell displays a scrolling list of all available ID’s.

All input tabs that collect data from the user contain a Status field directly beneath the label field. When all required values are entered, the status box becomes complete.

The cell color indicates whether a user can edit (change) the data in that cell. This convention serves to guide the user in entering appropriate data. For example, when the number of passes is changed, the cell colors change to indicate a change in the necessary data fields. This convention also protects data imported from a simulation data file.

The following list provides a list of cell colors, and what the cell colors indicate:

White

User entered value

Tan

Required value from user

Green

Estimated value

Blue

Value computed from other variables

Yellow

Value cannot be changed

Red

4.3 Output Case
The Output Case form (shown below) is used to select the process, hardware device, and model (correlations) to perform a device rating. Before the rating can be calculated, the selected process and hardware device must have a status of “Complete.”
If either the process or the hardware device status is “Incomplete,” the calculation status will show “Not Ready.” If the process and hardware device status is complete, a button labeled “Ready” will display in the row cell. If the output case has already been calculated, the calculation status line will display “Calculated.” Clicking on the cell in column of the row for Process Id, Hardware Id, or Model Id will display a drop-down list allowing selection of an item from the list.
For Model Id, the last entry in the list will be “Edit Models”. Selecting “Edit Models” will display the model manager.

The second column of the output cases will display a “Calculate All” button. Clicking on this button will cause any column with a “Ready” calculation status button displayed to be calculated.

4.4 Device Comparisons
Using the Device Comparisons feature, the user can rate multiple processing conditions and devices (e.g. sieve, valve, bubble cap, dualflow, and baffle trays; random and structured packings) all at once, view the results side-by- side for each device, and export to Microsoft Excel®, if desired.
The Device Comparisons tab is located under the Output Cases heading as the last tree item. When selecting the Device Comparisons tab, the user will see a grid that displays values from the selected calculated output cases, regardless of the Device Type.
The first field of the grid, Output Case Id provides a dropdown list of all output cases from the active DRP file. Once an output case is selected, the corresponding grid items are populated. The user can then compare key Input Parameters and Device Performance of all available devices. Figure 3.4-1 shows a Device Comparison example, in which Sieve, Valve, Dualflow, and Random Packing device performances are included. Note that the Device Comparisons grid is view-only and the user will have to navigate back to the output cases to make changes or recalculate cases displayed in the Device Comparison grid.

Device Rating Program User’s Manual Version 4.0
4.5.1 Performance Diagrams

DRP 4.0 Release Page 40

Beginning with DRP release 3.3, performance diagrams are available for all device types ­ trays and packings ­ within DRP.

The performance diagrams Wizard guides the user through generating the performance diagram for each device type. A corresponding output case must be calculated in order for a performance diagram to be generated.

Figure 4.5-1 shows an example performance diagram for a sieve tray case. Various curves appropriate for the device (in this case, Jet Flood, DC Flood, System Limit, Specified Entrainment and Weep rates) are generated over a wide liquid and vapor rates using FRI correlations, and the diagram is generated. Diagram properties may be adjusted from the Diagram Properties Window shown in Figure 4.5-2. Double-click on a diagram to display the Diagram Properties (formatting options) window.

If a System Factor is specified in the output case for a flood (jet or DC) estimation, the system factor is incorporated when calculating the curves.

The FRI system limit calculation (TR 136) has been added to all performance curves beginning with version 3.4. Pressure drop curves have been added for packing and sieve devices beginning with version 3.6.

DRP 4.0 Release Page 42

Additional options for performance diagrams are available when creating a new performance diagram by clicking on the “advanced” button in the bottom left corner.

The settings can be adjusted in the diagram setup ­ including adjusting the target curves ­ e.g. if the user wishes to plot 85% of jet flood curve rather than the default 100% jet flood curve. The user can also select which fields are plotted in the diagram by placing a check mark in the “Fields” column (first column). If the field is not applicable for the type of case to be diagrammed, the row will be grayed out. See Figure 4.5-3 below to see the layout of the advanced performance diagram setup.
