Download or read book Gas Pipeline Hydraulics written by Shashi Menon and published by Trafford Publishing. This book was released on 2013 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with the steady state hydraulics of natural gas and other compressible fluids being transported through pipelines. Our main approach is to determine the flow rate possible and compressor station horsepower required within the limitations of pipe strength, based on the pipe materials and grade. It addresses the scenarios where one or more compressors may be required depending on the gas flow rate and if discharge cooling is needed to limit the gas temperatures. The book is the result of over 38 years of the authors' experience on pipelines in North and South America while working for major energy companies such as ARCO, El Paso Energy, etc.

Available in PDF, EPUB and Kindle. Book excerpt: Our paper provides a review on the most relevant research works conducted to solve natural gas transportation problems via pipeline systems. The literature reveals three major groups of gas pipeline systems, namely gathering, transmission, and distribution systems. In this work, we aim at presenting a detailed discussion of the efforts made in optimizing natural gas transmission lines. There is certainly a vast amount of research done over the past few years on many decision-making problems in the natural gas industry and, specifically, in pipeline network optimization. In this work, we present a state-of-the-art survey focusing on specific categories that include short-term basis storage (line-packing problems), gas quality satisfaction (pooling problems), and compressor station modeling (fuel cost minimization problems). We also discuss both steady-state and transient optimization models highlighting the modeling aspects and the most relevant solution approaches known to date. Although the literature on natural gas transmission system problems is quite extensive, this is, to the best of our knowledge, the first comprehensive review or survey covering this specific research area on natural gas transmission from an operations research perspective. Furthermore, this paper includes a discussion of the most important and promising research areas in this field. Hence, our paper can serve as a useful tool to gain insight into the evolution of the many real-life applications and most recent advances in solution methodologies arising from this exciting and challenging research area of decision-making problems.

Available in PDF, EPUB and Kindle. Book excerpt: This study addresses the problem of designing a new natural gas transmission network or expanding an existing network while minimizing the total investment and operating costs. A substantial reduction in costs can be obtained by effectively designing and operating the network. A well-designed network helps natural gas companies minimize the costs while increasing the customer service level. The aim of the study is to determine the optimum installation scheduling and locations of new pipelines and compressor stations. On an existing network, the model also optimizes the total flow through pipelines that satisfy demand to determine the best purchase amount of gas. A mixed integer nonlinear programming model for steady-state natural gas transmission problem on tree-structured network is introduced. The problem is a multi-period model, so changes in the network over a planning horizon can be observed and decisions can be made accordingly in advance. The problem is modeled and solved with easily accessible modeling and solving tools in order to help decision makers to make appropriate decisions in a short time. Various test instances are generated, including problems with different sizes, period lengths and cost parameters, to evaluate the performance and reliability of the model. Test results revealed that the proposed model helps to determine the optimum number of periods in a planning horizon and the crucial cost parameters that affect the network structure the most.

Available in PDF, EPUB and Kindle. Book excerpt: "This book deals with a simple sounding question whether a certain amount of gas can be transported by a given pipeline network. While well studied for a single pipeline, this question gets extremely difficult if we consider a meshed nation wide gas transportation network, taking into account all the technical details and discrete decisions, as well as regulations, contracts, and varying demand. This book describes several mathematical models to answer these questions, discusses their merits and disadvantages, explains the necessary technical and regulatory background, and shows how to solve this question using sophisticated mathematical optimization algorithms."--

Available in PDF, EPUB and Kindle. Book excerpt: This thesis is about mathematical optimization for an efficient operation of gas transmission networks. The challenging question is how to expand and operate the network in order to facilitate the transportation of specified gas quantities at minimum cost. This problem is a major challenge for gas network operators. It is extremely hard to solve due to the combinatorial complexity of the active network elements such as compressors, the nonlinear physical characteristic of pipelines, and the immense sizes of the problem instances. Mathematical models and optimization techniques can result in huge gains for the network operators in terms of cost reductions and automated computations. We tackle this challenge by developing novel mathematical theory and associated innovative optimization algorithms for large scale instances. This allows us to produce solutions for a real-world instance, i.e., the largest gas network in Germany.

Available in PDF, EPUB and Kindle. Book excerpt: In natural gas pipeline transportation systems, network operators play a crucial role. Through compression power and pipeline geometry, they master the physics of the systems, allowing them to control the flow of gas between two points. Their decisions impact the entire production chain, from the suppliers to the consumers. Consequently, the management of pipeline systems requires an in-depth analysis of the influence of each decision. Each pressure change in the system may seriously impact the flow of natural gas, deeply modifying the revenue of the entire production and how it is divided between the different actors of the market. It is fundamental to understand how to master the system in order to control the money generated.From an economic point of view, natural gas pipeline production, transportation and sale creates wealth divided between the different actors in the sector: the profit of the producer, the consumer welfare and a combination of both for the network operator. This social wealth, should be maximized in order to generate the most benefit from the network for society. In order to do so, it is necessary to understand how much gas is flowing through each pipeline. If pressure values are fixed on an arbitrary basis, the dispatch of natural gas in the network will not be optimized. The loss of social wealth generated can be considerable given the important volumes transported through pipeline those days. In the market of natural gas transportation, if the pressure at the nodes is wrongly chosen, it could be disastrous for a company. How could any producing/transporting company avoid wasting this significant amount of money? What are the solutions available for the natural gas pipeline engineers to dispatch natural gas in order to maximize the social wealth generated?This issue can be stated in the corresponding two situations: For the construction of a new pipeline network, how should the geometry of the different pipes be chosen in order to transport natural gas in an optimal way? For an existing pipeline network, how should the pressure drops be chosen to maximize the social wealth of the producing/transporting company?The goal of this study is to provide network operators with the parameters to answer those situations. By fixing the pressure values at the nodes of the system, it is possible to maximize the economic value generated by the natural gas transportation and sales. Additionally, running the simulation on different natural gas network configurations = inform the company on how to choose the ideal geometry factors of each branch of pipeline.Midthun et al. (2009) suggested two different methods to address this problem. The first one, the Independent Static Flow (ISF) method is a straightforward way to find a solution. Neglecting the physics of natural gas, this method assumes that every pipe of the system is running at maximum capacity. The method is very easy to use and implement. Nevertheless, the solution provided is unrealistic: as the physics of natural gas is not respected, it is impossible to practically apply the method on a real network. Hence, this method can only be used to give an idea of how to regulate the flows, and an operator could only try to guess the pressure values at the nodes that could help to get closer this ideal situation on his network. The loss of economic value of natural gas from the arbitrary choices of the operator is a concern. Additionally, the solution arbitrary applied by the operator will generate far less social wealth than the ideal solution given through ISF Method due to the application of the physics of natural gas transportation.To address this issue, the second method proposed by Midthun et al. (2009), the Taylor Development Method, relies on an approximation of the underlying physics to solve for the optimal solution. In order to improve the relevance of the results to the constraints of the pipeline network, Midthun et al. decided to modify the nonlinear constraints of the system, .However, the accuracy of this approach has a price: the more accurate the solution, the more computationally difficult the optimization becomes. Figure 1: The fragile optimum for the Taylor Development MethodFigure 1 illustrates this complex choice. Thus, the user remains struggled in a compromise to find the right equilibrium between quality of the result and time (and so money) of computation. The situation is even worse for large network, as the number of constraining equations greatly increases for each additional pipeline on a network.This compromise between size of network/quality of results on one hand and computational feasibility on the other hand cannot be satisfying. Today, natural gas companies have to deal with networks of several hundred of pipes. An accurate solution would be too hard to solve for, and decreasing the accuracy expectations may cause a large waste of social wealth. In order to avoid this loss, this paper is suggesting another method, based on Ayala et. al.'s (2013) Linear-Pressure Analog Method. Instead of adding extra constraining equations to take account for the nonlinearities of natural gas physics, it is possible to simplify the system. Assuming a linear relationship between natural gas flow rate with respect to pressure drop, the system become smaller and easier to solve. In other words, physics of natural gas is assumed to be similar to the one of laminar liquid flows. From here, a correction is applied to the solution found, taking account for the nonlinearities inherent in real natural gas behavior. The process is iterated until convergence is reached. This method is both feasible and accurate with limited computational demands. Consequently, with any standard computer, a production/transportation company can obtain the ideal and realistic dispatch of natural gas in its network, and optimize the economic value generated by its natural gas transportation.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project is to develop a Virtual Pipeline System Testbed (VPST) for natural gas transmission. This study uses a fully implicit finite difference method to analyze transient, nonisothermal compressible gas flow through a gas pipeline system. The inertia term of the momentum equation is included in the analysis. The testbed simulate compressor stations, the pipe that connects these compressor stations, the supply sources, and the end-user demand markets. The compressor station is described by identifying the make, model, and number of engines, gas turbines, and compressors. System operators and engineers can analyze the impact of system changes on the dynamic deliverability of gas and on the environment.
