Transient Flow Analysis of Fast Valve Closure in Short Pipelines

The present papers presents an analysis of transient pressure behavior in short pipelines for tanker’s loading at a marine terminal. The analysis was focused on the interaction of several dynamic components that are present in the line, such as check, flow control and block valves, pump and pipe elasticity. The purpose of the analysis is to maximize flow rate through the line thereby minimizing tankers dockage time, without exceeding the allowable pressure limits. A commercial software was employed in the calculations that were able to reveal the complex interaction of the dynamic components present.
