With the completion of the second line project of West-East Gas Transmission in 2011, the third line of West-East Gas Transmission will be started soon and the fourth line and the fifth line will be started in recent five years. China will form one of the largest natural gas pipeline network in the world. The gas supply mode will be changed from single gas source and single-pipeline supply to multi-source and multi-pipeline supply through regulation and coordination, which will impact on existing pricing mechanism and operation mode of Chinese natural gas industry violently. Depending on the development trend of natural gas pipeline network, the regionalization management mode of natural gas pipeline will be implemented gradually. Chinese natural gas industry also needs to develop a new-type market-oriented operation mode with clear interfaces between production, transportation, distribution and customers so as to facilitate the optimal allocation of resources. By the customized scientific research of CNPC (China National Petroleum Corporation), combining with existing pricing mechanism of natural gas pipeline and economic characteristics of long-distance natural gas pipeline transportation in China, the paper studied the pricing mechanism problem of combined transportation of multi-source and mutli-pipeline gas supply in the regionalization management mechanism, presented the idea of pricing formulation method of two kinds of pipeline network transportation based on standard rates of pipeline transportation and service cost rules, formed pricing formulation system of natural gas pipeline transportation, introduced the design idea, structural construction, distribution method and key points of natural gas pipeline transportation in details, and demonstrated the methods by example calculation. The methods presented in the paper can meet the pricing requirements of natural gas pipeline network transportation, remedy the defect in existing price accounting mechanism, solve the problem that the income and expenses among different interest bodies are not balanced, and facilitate the rapid development of natural gas pipeline business.

Competition in the natural gas industry grows steadily. The demand for natural gas transportation has typically exceeded the capability of the existing natural gas pipelines within Canada for several years. Even though intense competition exists with producing and marketing natural gas, limited transportation options limits the business opportunities available for energy companies. This competitive spirit is driving the Alliance Pipeline Project. Once the pipeline is complete, producers will have an additional transportation option to move their products to Chicago, Illinois, which is emerging as an important business hub for natural gas marketing. Designing and constructing a natural gas pipeline in the late 1990’s will allow Alliance Pipeline Limited the ability to implement the latest technology into all aspects of the design.

Speedup Ratio

The numerical simulation efficiency of large-scale natural gas pipeline network is usually unsatisfactory. In this paper, Graphics Processing Unit (GPU)-accelerated hydraulic simulations for large-scale natural gas pipeline networks are presented. First, based on the Decoupled Implicit Method for Efficient Network Simulation (DIMENS) method, presented in our previous study, a novel two-level parallel simulation process and the corresponding parallel numerical method for hydraulic simulations of natural gas pipeline networks are proposed. Then, the implementation of the two-level parallel simulation in GPU is introduced in detail. Finally, some numerical experiments are provided to test the performance of the proposed method. The results show that the proposed method has notable speedup. For five large-scale pipe networks, compared with the well-known commercial simulation software SPS, the speedup ratio of the proposed method is up to 57.57 with comparable calculation accuracy. It is more inspiring that the proposed method has strong adaptability to the large pipeline networks, the larger the pipeline network is, the larger speedup ratio of the proposed method is. The speedup ratio of the GPU method approximately linearly depends on the total discrete points of the network.

Abstract. High-accuracy beam pointing is one of the key problems in the airborne laser remote sensing of natural gas pipeline leak. In response to the domestic demand for the long-distance natural pipeline leak detection, this study proposes an airborne laser effector for autonomous pipeline alignment based on CH4/H2S detector. Mainly structured on 2DOF serial mechanism, the device under discussion is designed with a control system operated on IPC and PMAC, followed by the design of hierarchical modular software. Once completed, the device is placed for indoors pointing experiments as well as simulated airborne test. The results show the effector can conduct full-angle scan of the pod area, achieve a static measuring precision of less than 0.4m as an alignment point is about 100 meters from the laser and detect leakage in dynamic simulated experiment, which meets with the design requirements. In other words, both the design and control algorithm are proved to be feasible. The effector holds an important engineering value for solving the problem of remote detection of the natural gas pipeline leakage.
