The abundance of natural gas in the United States because of the number of existing natural gas reserves and the recent advances in extracting unconventional reserves has been one of the main drivers for low natural gas prices. A question arises of what is the optimal use of natural gas as a...

The value of transmission capacity is hard to assess due to the presence of different issues: physics of power networks, economics of power systems and reliability criteria. Evolving supply and demand trends, however, create interest in increased transmission capacity, especially between...

Natural gas stream must be preheated before pressure reduction takes place at natural gas pressure drop station (CGS). It ensures that the natural gas stream remains above hydrate-formation zone. The heater which is employed to provide the required heat consumes a huge amount of fuel. In this...

Saudi Arabia has ambitious plans for nuclear power. Given this context, this paper examines the economics of nuclear power and compares it to two other sources of electricity, natural gas and solar energy. It calculates the costs of electricity generation, water desalination and the opportunity...

Dual-fuel gas-diesel engines present an environmentally attractive substitute for conventional diesel engines that operate with a finite resource petroleum fuel and emit large amount of harmful emissions. However, this engine configuration, in which the gaseous fuel is used as a primary fuel...

The use of natural gas in compression ignition engines as supplement to liquid diesel in a dual fuel combustion mode is a promising technique. In this study, the effect of DF (dual fuel) operating mode on combustion characteristics, engine performances and pollutants emissions of an existing...

This paper presents part-load evaluation of a natural gas-fired chemical looping combustion (CLC) combined cycle with CO2 capture. The novel combined cycle employs an air-based gas turbine, a CO2-turbine and a steam turbine cycle. In this combined cycle, the CLC reactors replace combustion...

The debate over the availability of conventional natural gas has been nearly as strong as that for conventional oil. In Europe, the debate is strengthened due to the region’s dependence on natural gas from outside countries. In addition, concern has been expressed by some energy experts in...

The pressure in the main natural gas transport pipelines should be reduced for proper consumption in vicinity of cities. A common procedure of reducing pressure in natural gas station (city gate station, CGS) is using expansion valves, which causes the waste of large amount of exergy...

The cement and lime industries are major contributors to the anthropogenic CO2 emissions to the atmosphere. By combining the CO2-releasing calcination of CaCO3 with the CO2-consuming dry-reforming of CH4, and by further combining these endothermic reactions with the exothermic partial oxidation...
