Abstract. The steady-state hydraulic and thermal simulation of the gas gathering
pipeline network with predicting methods of natural gas hydrates are discussed in
this paper. Compressors, valves, heating furnaces and other equipment in pipeline
network are also considered. Nodal analysis method accompanied by the linear
approximation is implemented to solve the hydro thermal simulation equations.
Chen-Guo model is used for calculating hydrate phase equilibria and secant line
method is applied to solve this model. Steady-state simulation and hydrate prediction results of the pipeline network are compared with the calculation results
of TGNET and literature respectively. The results show the effectiveness and
accuracy of the pipeline network steady-state simulation and hydrate prediction
methods.
Keywords: Gas gathering pipeline network · Natural gas · Steady-state
simulation · Non-pipe elements · Hydrate prediction
1 Introduction
With the sustained development of natural gas industry, natural gas as a clean energy
has been increasingly important. From natural gas production to final users, the natural
gas transmission and distribution network plays an important role in the reliability of
gas transportation. Therefore, accurate calculation method of the natural gas gathering
pipeline network has been one of the important requirements during the construction
and operation of natural gas pipeline network. However, there was little work on simulation of the natural gas gathering pipeline network at present, we want to know whether
the existing calculation methods of gas transmission and distribution network are suitable for gathering pipeline network. In addition, the judgement of hydrate formation in
the gathering pipeline network also needs to be further studied. Therefore, this article
combines the steady-state hydrothermal simulation of the natural gas gathering pipeline
network with the prediction of the hydrate generation conditions in the pipeline to make
a preliminary study on the simulation method of the complex natural gas gathering and
transportation network system.
