Serving and Supporting Chemical Engineers
At CHEMSTATIONS, we want to optimize your process, make your presentations exponentially better, and get your ideas the attention they deserve. That’s why we have sought and continue to seek your input. It’s also why CHEMCAD Version 7.0 is much more intuitive and delivers professional, presentation-ready flowsheets faster and more efficiently than ever.
CHEMCAD Version 7.0 gives you three key benefits.
You can streamline your work with an all-new graphics engine.
- Building, rebuilding, and working with flowsheets is easier and more intuitive than ever.
- Common flowsheeting operations now require fewer mouse clicks, and generally less work, to complete.
- Graphics operations conform to standards set by other commonly used software tools.
Your results look better and make you look better.
- Enjoy professional-looking unit operations and flowsheets at any zoom level.
- Choose from three UnitOp color schemes--color, grayscale, or wireframe--and use them in any combination on your flowsheets.
- The all-new reporting engine is more customizable than ever.
You have a platform to grow on in future versions.
- We are rebuilding the calculation engine to be faster and more efficient.
- We will expand the reporting engine to new standards like HTML & XML.
- We will add features like auto-building flowsheets from text topology input and third-party applications.
We have a reputation for getting you to the right answers efficiently. Now those answers look as good as all the hard work you put in getting there.
CHEMCAD Version 7.0 New Features
The CHEMCAD interface has been refreshed with a more modern look, sophisticated graphics, and a neutral color palette. (The View > UI Appearance command, with two alternative color palettes, is provided as a beta feature.) The toolbar has been overhauled with a new look and numerous new drawing tools.
Importing a CHEMCAD 6 simulation into CHEMCAD 7 is quick and easy. Standard UnitOp symbols from the previous version will map to the appropriate new versions, and the option to use a CC6 UnitOp look is also available. Any custom symbols will be re‐created on the imported simulation.
UnitOp palettes: Right‐click to see a subpalette of alternative symbols for a UnitOp. From there, [CTRL]‐click a symbol to set it as the default. Palette contents are locked against further changes by default, but a single click unlocks them for customization. Users can change the order of UnitOps within a palette, create their own custom palettes, and control which built‐in and custom palettes are displayed. The Reset All Palettes command can quickly restore palettes to installation defaults.
All UnitOp symbols on the palette are displayed with names for easy identification. Hovering over a symbol brings up a descriptive tooltip. Feed and product arrows are displayed at the top of every palette for easy access.
Placing a UnitOp on the flowsheet is now a simple matter of dragging the symbol from the palette to the workspace and then releasing the mouse button.
Color Schemes provide three distinct default appearances for UnitOp icons: Grayscale, System Color, and Wireframe. Grayscale provides a three‐dimensional look in shades of gray; System Color uses the same approach, but with tastefully muted colors; and Wireframe gives the flowsheet a PFD‐ready appearance. Users can also create custom color schemes, and apply a color scheme to an entire flowsheet or specific UnitOp icons on a flowsheet.
UnitOp inlet and outlet indicators are visible all the time, but are hidden when the flowsheet view is substantially zoomed out.
Drawing streams in CHEMCAD 7: Simply point at an outlet, click, and drag the mouse to an available inlet. Release the mouse button and the stream appears. To route the stream precisely, click as you drag to establish waypoints. Default stream routing is improved over previous versions of the program.
The Stream Edit dialog now displays user‐specified values in green.
The Stream Styles feature enables users to set the appearance of stream intersections and arrows.
After they are drawn, stream end points can be moved from one port to another, within the same UnitOp or on a different one, simply by clicking and dragging. Stream information is preserved in the move.
ID placement for streams and UnitOps: By default, UnitOp IDs are placed just above and to the left of the UnitOp icon; stream IDs are placed on the longest segment of the stream line. Object IDs move accordingly when objects are moved.
To change the placement of a flowsheet object’s ID, click to select the object (stream line or UnitOp), then hover over the ID until a curved hand cursor appears. The click and drag the ID to its new location and release the mouse button. A deliberately placed UnitOp ID keeps its position relative to the UnitOp symbol if the symbol is moved. Stream IDs move less predictably because of the nature of streams (changing size and shape); because of this, the right‐click menu for streams offers the Reset ID Position command, which returns the stream ID to its default position.
Customizing report information is much easier, and you can now customize Quickview information as well. A new feature called Property Sets enables you to determine which stream information is included—and the order in which it’s displayed—in the Quickview pop‐ups, stream composition reports, and stream property reports. You can create custom sets with any combination of properties, and have them display in any order. Displaying vapor/liquid/solid properties in separate columns in reports is also an option with property sets.
Report output options now include Microsoft Word and .CSV, as well as the internal CHEMCAD report viewer, WordPad, and MS Excel.
Stream property and composition reports have been combined into the Report > Stream Reports commands. Stream data can be displayed by phase.
Report generation has been improved and streamlined. CHEMCAD can now be closed without the need to close any Excel reports first, and reports reside only in temporary directory unless the user deliberately saves them.
Additions to the CHEMCAD component database include more than 180 new components, as well as new UNIFAC groups. Users can now add more than 8 subgroups for a component. Several new DIPPR equations have also been added.
Users with a UAM will not need to recompile for CHEMCAD 7.
UnitOp Designer is the new tool for creating your own UnitOp symbols, which you can assign to any UnitOp type. This tool is integrated within CHEMCAD, and easier to use than the previous Symbol Builder tool. Users can easily clone symbols, to change port configuration or other details without having to draw another symbol from scratch.
The Publish to Palette feature enables users to place certain objects from a flowsheet—an imported image, a UnitOp symbol that has been flipped or otherwise altered, or a symbol imported from CHEMCAD 6, for example—on a UnitOp palette for later use. These items can be assigned any UnitOp type, or left without a type.
Drawing tools now enable users to toggle on and off features such as Grid, Snap to Grid, Snap to Center, and Lock/Unlock Flowsheet Objects. Other handy flowsheet tools include Flip, Rotate, Group/Ungroup, and options for alignment, spacing, and object order. Tools for adding text boxes and primitive shapes to a flowsheet are now found on the toolbars, rather than buried in the palette.
Flowsheet text is easy to add and manipulate, with total control over the appearance of text in UnitOp/stream IDs and databoxes, as well as in text boxes.
Right‐click menus for streams and UnitOps have been expanded to include more commands. Right-clicking anywhere on the workspace also brings up a new menu, with access to helpful flowsheet selection and viewing commands.
The Format > Import Bitmap command is now called Format > Import Image, and allows users to import .PNG and .TGA files as well as .BMP, .JPG, and .GIF.
The Batch Reactor UnitOp has been renamed to Vessel Reactor, to better represent the features it provides.
Databoxes have a new, streamlined appearance, and users have more control over their content and formatting. It’s now possible to alter an existing databox to display different items or change the order of items; simply right‐click and select Edit Databox, then make changes using the property set controls. Databoxes can be resized with sizing handles on all sides, like other flowsheet objects.
Users can now set the location of temporary CHEMCAD files used for simulation recovery. Placing these files in a local directory can speed up file access for users whose CHEMCAD files reside on a network.
The View > Reset User Interface command provides a quick and easy way to return to default interface settings.
Help topics are now available for the Economics tool.
The Layers tool is not incorporated in CHEMCAD 7. Please contact us if you used this feature and would like to see it return in the future.
