ProMax uses Microsoft Visio as its drawing package. You will find that Visio’s functionality empowers you to enhance your process flowsheets. Simply drag and drop blocks, streams and process data onto your flowsheet. Combining ProMax, Visio and you is true innovation.

Flowsheet Drawing

• Customize your flowhseet through several annotation options. Display stream properties, material and energy balance data, user defined variables and standard text box annotation.
• Blocks (shapes) representing the corresponding unit operations such as Heat Exchangers, Distillation Columns, etc. are placed on the flowsheet and then connected by Process Streams.
• ProMax blocks (shapes) are contained in a movable window to the left of the flowsheet.
• Energy Streams are also attached to certain blocks such as Heat Exchangers, Pumps, and Compressors to represent the flow of energy into or out of the particular unit operation.
• ProMax allows the user to size, flip, rotate, move, and label all blocks and streams.
• Multiple flowsheets within a project may also be linked using the Cross Flowsheet Connector.
• To place a block on the flowsheet simply drag the desired block icon to the flowsheet.

Process and Energy Stream Connection Points

• All blocks have designated connection points for both Process and Energy Streams.
• These connection points are not interchangeable (i.e. an Energy Stream may not be attached at a Process Stream connection point).

Dragging Process and Energy Streams to the Flowsheet

• Process and Energy Streams can be dragged onto the flowsheet and connected to blocks without using the Connector Tool.
• Select an Energy or Process Stream stencil and drag it onto the flowsheet.
• Drag the stream's begin and end point to the desired connection point on each block.

Using the Visio Connector Tool

• To place either Energy or Process Streams on a flowsheet using the Visio Connector Tool, click on the Connector Tool located on the Visio toolbar.
• To attach Process Streams to blocks, click and drag the connector's begin point to the Process Stream connection point on the first block, then click on a Process Stream connection point on the second block.
• To attach Energy Streams using the Connector Tool, simply click the Connector Tool then click on Energy Stream from the stream stencils. The Connector Tool will draw Energy Streams instead of Process Streams.

Labeling Blocks and Streams

• The block or stream name may be modified at any time.
• Open the target stream or block dialog in the Project Viewer and type the desired name in the Name field.
• Alternatively, you can right-click on the block or stream in the Flowsheet View and select "Rename". Then type the new name directly on the flowsheet.
• The name may be any combination of letters, numbers, and spaces.

Quickly recognize block status by color

Color Convention for Block/Stream Status

	Color	Block Status	Stream Status	Comments
	RED	Unconnected	Unsolved	Stream is not ready to execute, specifications are missing
	BLUE	Unsolved	N/A	Block has all required connections
	BROWN	N/A	Unsolved	Stream is defined and ready for execution
	ORANGE	Approximate Solution	Approximate Solution	Note: The Recycle block is considered to have an Approximate Solution until the Recycle functions are below the specified tolerance. Other streams and blocks may have an Approximate Solution if the flash solved outside of correlations for pure streams. In a Column, the function tolerance may not have been fully met.
	GREEN	Solved	Solved
