Commercial & Industrial Application/ Permanent Lng Installation - Case Study
Use of LNG to replace other liquid fuels (propane, distillate fuel oil, bunker/residual fuel) is increasing worldwide. There are several incentives driving these conversions. Initially after the shale gas boom in the USA, the incentives were largely economic as natural gas prices plummeted, also bringing down the cost of LNG vs. conventional liquid fuels. The rapid growth of both international ...

Exergy analysis of geothermal electricity using the Kalina cycle
The geothermal energy that is stored in the earth is so vast that could supply all the energy needed by humanity. The difficulty in tapping this energy lies in its diffusivity. The geothermal energy in regions near volcanoes is close to the surface and easy to use economically. In this paper a vapour dominated system will be examined. The electricity that is produced from such a system is ...
