Avid gets a lot of these requests! A producer of specialty chemicals contacted Avid to design and deliver an Emerson Delta V control system. This system needed to provide automated batch processing capabilities. The challenge was to design a system capable of manual operation in case the system failed.
The company was replacing an existing batch system. The development of the new system required complete operator buy-in. These requirements prevented an installation using conventional batch configuration techniques. The system needed to eliminate risks from a batch system failure or operator errors.
The proposed system would incorporate the basic concepts of the S88 standard for batch process control. S88 provides a consistent set of standards and terminology for batch control. S88 also defines the implementation of the physical model and procedural model. S88 permits system designers to create a universal model for batch control. In this case, strict adherence to S88 would not provide the functionality that the customer required.
