Maximum Transient Pressures in Batch Pipelines due to Valve Closures

In a batched pipeline, the transient pressure due to a rapid valve closure depends on batch sequences, batch interface locations, and batch volumes. Since an infinite number of potential batch scenarios exist, it is necessary to identify a worst-batch scenario where the maximum transient pressure occurs for the transient event of the valve closure. This study demonstrates that the worst-batch scenario is the densest fluid filling the pipeline between the closed valve and its upstream boundary and the least dense fluid filling the pipeline between the closed valve and its downstream boundary. For a surge-dominated transient event, the worst-batch scenario could be a smallest batch of the densest fluid placed just upstream of the closed valve with the least dense fluid filling the remaining volume of the pipeline.
