This paper introduces the source and utility circumstance of natural gas in China. The utility circumstance of natural gas is discussed in detail, such as, natural gas as feedstock is produced to acetylene; natural gas is used to cut metal; natural gas is applied to generate ethylene; natural gas instead of heavy oil is fired to produce chromium trioxide. In so doing, the energy demand of China...

Compressibility factor and viscosity of natural gasses are of great importance in petroleum and chemical engineering. To calculate the natural gas properties in the pipelines, storage systems and reservoirs, the exact values of gas compressibility factor and viscosity are required. A new method that allows accurate determination of compressibility factor and gas viscosity for all types of: swee...

Background and Aims: Natural gas pipeline network is an important part of a city’s infrastructure for energy transmission. As the gas pipeline network becoming vaster and more complex, accident caused by the leak of gas pipeline network occur. Accidents consequences caused by gas pipeline rupture, can directly threatening the safety of persons and properties in the city. Thus, it is neces...

Using natural gas is known as a clean energy resource and apart from environmental aspect, it is economically and politically of great importance so that countries having conventional and unconventional gas resources have increased investment in novel tech developments especially in unconventional ones. The aim of this study is to analyze the effect of shale gas production on the gas price in t...

We investigate the pricing formation of natural gas markets on three different continents (Europe, Asia and North America). We find that natural gas markets showed a strong relationship with the crude oil market between 1992 and 2001 and natural gas prices tended to thermal parity with crude oil prices. From 2002 natural gas markets exhibited a less pronounced relationship with the crude oil ma...

Exergy analysis is important and has been widely used to evaluate the thermodynamic efficiency of a variety of processes. Therefore, there is a need to develop a tool for monitoring exergy of a process in real-time and for studying the effects of various feed, equipment, process and environmental changes. The ultimate aim of this work is to develop a tool to enable dynamic and online exergy ana...
