Natural gas plays a growing role in the energy mix by displacing coal due to its relative economic and/or environmental advantages A process of natural liquid (NGL) recovery utilizing internally generated achieve efficiency was designed. The utilizes heat from compressor end turbo-expander provide required maintain appropriate operating conditions at intermediate and bottom sections demethanize...

The soil is a heterogeneous and anisotropic medium. Hydraulic conductivity, an intrinsic property of natural alluvial deposits varies both deterministically and randomly in space and has different values in various directions. In the present study, the permeability of natural deposits and its influence on the seepage flow through a natural alluvial deposit is studied. The 2D Finite Difference c...

Municipal solid waste landfills are significant parts of anthropogenic greenhouse gas emissions. The emission of significant amount of landfill gas has generated considerable interest in quantifying such emissions. The chemical composition of the organic constituents and potential amount of landfill gas that can be derived from the waste were determined. The chemical formulae for the rapidly bi...

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...

Bioceramics such as hydroxyapatite (HAP) have been conventionally deposited by plasma spray technique. However, due to the inherent high temperature in the plasma, deleterious effects such as evaporation, phase alteration, residual stress, debonding, and gas release etc., commonly occur in these coatings. This paper presents a novel approach to deposit bioceramic coatings at temperatures well b...
