The DAT file also includes information on the connectivity of the network which components are included in the network and how they are connected to other components in the network. This file contains general information, such as what sort of fluid is being used and what units are to be used throughout the simulation. We shall first set up the setup, then we can enter the supporting libraries, then the network itself.Īll the information which is specific to a particular problem is stored in a Network Data File, or DAT file. Different applications which use the same pipe schedules, pumps or valves can share the same library files, as the data contained in these files is independent of the application.

The information entered is stored in four files: the Network Data File (or DAT file), the Pipe Schedule File (or PDF), the Pump Library (PLB) and the Valve Library (VLB). In this section we will gather and enter all the information that PIPENET needs to perform the simulation. 1.3 Summary of Data Used When approaching a new problem, it is useful to start by collating all of the required data for each of the components. 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. Schematic diagrams representing the network inįigure 1-2 Schematics Of The Networks At every junction between components or pipes, there is a "flow node" (encircled in the diagrams).

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.
