1.1.1 The Scenarios Two basic scenarios are considered: 1.1.1.1 Planned Shutdown This is an everyday occurrence effected by the closure of shutdown valve HV5002 by a local manual switch or from the control room. To investigate the effect of an acumulator in reducing surge pressure.

To establish if the pressure surges experienced by the existing valves due to valve closures are below the allowable limit of 25.5 bar G.The objectives of the study are the following: As this is the first example, the methods used here are discussed in some detail.

Most of the techniques used in this simple case are also applicable when solving other problems with PIPENET Transient Module. The design of the section under consideration is sketched below.įigure 1-1 Sketch Of The Engineer's Problem This example illustrates not only how easy it is to predict pressure surges using PIPENET Transient Module, but also how quickly one can appraise a proposed solution to the problem. An important aspect of the design was ensuring that pressure surges arising from the closure of valves would not cause damage to the pipework resulting in product spillage. The environmental implications were of major concern in the design because leakage of the product into the sea could have serious consequences. APPLICATION 1: SURGE ANALYSIS IN PRODUCT EXPORT LINE FROM A PETROCHEMICAL PLANT TO A JETTY 1.1 The Problem In our first application we consider an engineering company that had been contracted to design the product export pipeline from Product Storage Tanks in a petrochemical plant to a Jetty into loading tankers.
