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 ...
Stabilis provided the very first LNG and equipment solution for oil & gas frac operations in 2013 working with a major, integrated oil company in the Eagle Ford shale basin. Stabilis has experience supplying vaporized LNG to a 100% gas-powered turbine frac solution, as well as supplying more conventional pressure-pumping units powered by dual fuel reciprocating engines. Since 2013, we have ...

Greenbelt Resources Corporation (OTC: GRCO) an innovator of sustainable energy production systems, today announced that it was selected by EcoPAS, a California company, to manufacture its PAS (Passive Alcohol System) – a revolutionary pollution control device that captures and transforms gaseous ethanol emissions into quality spirit products. The full-scale PAS will be utilized in a soon ...
We have reported aluminium doped zinc oxide (AZO) film grown on sapphire substrate using dual–plasma–enhanced metal–organic chemical vapour deposition (DPEMOCVD) system. The crystalline quality, surface morphology, optical properties, and electrical characteristic of AZO film depend on the deposition temperature and Al content. The 185°C–deposited and 2.88 at%–Al–doped AZO film shows a strong ...
Performance comparisons of two vapour compression refrigeration cycles (CYC1 and CYC2) based on the exergetic analysis with three natural refrigerants: ammonia, propane and isobutane are presented using vortex tube as an expansion device. Effects of various operating and design parameters on the performance improvement are presented. Results are shown that the exergetic efficiency improvement ...
In this paper, energy and exergy analyses and performance comparison of R22 and its alternatives, R407C and R410A, in a vapour compression refrigeration system (VCRS) have been presented. For this aim, detailed first law (energy) and second law (exergy) analysis of these three refrigerants have been performed. ...
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 ...
The sight of gum wads stuck to floors or other surfaces is definitely an offensive one that can turn away people. In fact, a single chewing gum on an otherwise pristinely clean surface can ruin the entire impression of the place. This is especially applicable in the case of places, such as hospitals, religious institutions, malls, and offices that have to look welcoming and impressive at all ...
