The pump includes a nonreturn valve to protect it from flow reversal and so this is inserted between the pump and the first pipe. Every item in the network and every node must be labelled. Every pump and valve in any network has a single "information node" associated with it (labelled I/1, I/2 or I/3) which will be used to tell PIPENET how the device is to operate during the simulation.

This is an infrequent occurrence that takes place if the shutdown valve HV5002 fails to close, when the hydraulically operated ERC (Emergency Release Connection) comes into effect. 2 Single stage valve closure with an accumulator 1.1.1.2 Emergency Shutdown In this scenario a number of cases are considered: Two stage valve closure type 1 without an accumulator Two stage valve closure type 1 with an accumulator Two stage valve closure type 2 without an accumulator Two stage valve closure type 2 with an accumulator Single stage valve closure without an accumulator

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. The objectives of the study are the following: 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. 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.
