Topic 4.4.1: Segments
- Segments
- Batch processing systems often have built-in limitations that are not evident in the process model.
- InBatch addresses limitations in material transfer capabilities by modeling shared equipment and piping using segments. Segments are a powerful tool for limiting material transfers in a batch process.
- Segments limit material transfer capabilities. Segments are parts of connections.
- Multiple connections can have the same segment or segments assigned to them.
- Once a connection is allocated for use by InBatch, all segments assigned to that connection are unavailable for use by any other connection - even by the same batch.
- A pump or transfer panel or piece of pipe modeled as a segment can only be used by one connection at any one time.
- As with any powerful tool, when used correctly, it can yield desired results with incredible ease.
- Analogy
- Picture a chisel in the hands of a sculptor. You can't make a piece of rock bigger with a chisel!
- Adding segments to an InBatch process model will never increase the material transfer capabilities of the system.
- The desired result is to faithfully represent the true limitations of our batch process without going too far and introducing artificial limitations in our model which are not in our process.
- Examples of Segments:
- Shared Process Piping
- Common Valve
- Common Pump
- Flow Meters
