Before defining equipment configuration, you need to have a complete understanding of the physical layout of the plant equipment. The plant's P&ID drawings are a good place to start.
It is clear that some elements of the process are nearly identical. At a high level, all the equipment pieces for the color tanks are the same, as are the major pieces for the blenders. At the lowest level, the valves used for output from the color tanks are similar to the valves used in other parts of the process, such as input of base and color ingredients to the blenders. Using the DeltaV system's class-based design features will greatly simplify configuration of these elements of the process system.
