Calorific value metering offers unique advantages in the natural gas industry. Based on a graph neural network (GNN), this study proposes a method for metering the gas calorific value in natural gas transportation. Graph theory is introduced to consider the effects of physical topology and node properties in natural gas pipeline networks.

Unsteady natural gas flow within pipeline network, an analytical approach
Journal of Natural Gas Science and Engineering, 2016Abstract The natural gas pipeline network (including distribution network) may be subjected to some extreme conditions such as pipeline rapture, sudden changed demand and etc. The behavior of natural gas pipeline network should be properly identified to prevent network failure and have continued pipeline operation under these extreme conditions ...

Research on transient composition tracking in natural gas condensate pipeline networks
Physics of Fluids, 2023Offshore pipelines are hailed as the “lifeline” of an offshore oil and gas production system and are essential for offshore oil and gas development. Component tracing technologies for the oil and gas multiphase transmission pipeline networks need to be urgently developed to predict the fluid composition changes in pipeline networks. Instead of assuming

Analogical Approach for Optimizing Natural Gas Transmission Pipeline Network System
Advanced Materials Research, 2011The increase in demand for natural gas in different sectors attracted different scholars in optimizing the operation and configurations of natural gas pipeline network (NGPN) systems. Even though there have been reports regarding the attempts of solutions for optimizing NGPN problems, the issues of NGPN regarding energy minimizations are not fully ...

Network modelling and prediction of retrograde gas behaviour in natural gas pipeline systems
International Journal of Engineering Systems Modelling and Simulation, 2016As retrograde gases are transported through pipeline systems, retrograde condensation may occur. The presence of this additional liquid phase is responsible for additional pressure losses in natural gas surface production systems. Gases and liquids have markedly different routing behaviour when moving concurrently through a network system and the ...

A Hybrid Meta-heuristic Approach for Natural Gas Pipeline Network Optimization
2005In this paper we propose a hybrid heuristic solution procedure for fuel cost minimization on gas transmission systems with a cyclic network topology, that is, networks with at least one cycle containing two or more compressor station arcs. Our heuristic solution methodology is based on a two-stage iterative procedure.
