Optimising Compressed Natural Gas filling stations reservoir pressure based on thermodynamic analysis
A theoretical analysis has been developed to study the effects various parameters on the Compressed Natural Gas (CNG) filling process and the conditions. The analysis is based on first and second laws of thermodynamics, conservation of mass and the AGA8 Equation of State (EOS). Based on AGA8 EOS and thermodynamics relationships, the required properties of natural gas mixtures have been ...

Sensitivity analysis in a simulated auto thermal Natural Gas reforming process
Auto Thermal natural gas Reforming (ATR) is one of the mostly used conventional hydrogen generation technologies by the highly developed countries. ATR reactors do not need any direct or indirect heat exchanger, and that is why they are more compact and so preferable than the other reformers. In this study, a process including reformers, carbon dioxide sequestration and a cryogenic separation ...

Energy and exergy analyses of a steam reforming process for hydrogen production
Hydrocarbon steam reforming is an important process for hydrogen production. In petroleum refineries, steam reforming is most commonly used for hydrogen production from naphtha and light hydrocarbon gases (methane, ethane and propane). Since the hydrocarbon steam reforming system is one of the highest energy intensive systems in a petroleum refinery it should be directed to a more efficient use ...

Fuel upgrading improves cars operation
Gasoline is the mix of easily boiling liquid various hydrocarbons received at distillation of oil, natural gas reclamation, processing of fuel firm types and at secondary processing of products of oil distillation. The most important for gasoline are detonation requirements and fractional structure on which their properties depend. Operation without detonation of the engine is reached by gasoline ...

Exergy analysis and performance evaluation of CNG to LNG converting process
A process for converting Compressed Natural Gas (CNG) to Liquefied Natural Gas (LNG) is modelled thermodynamically and effects of design and operating parameters on exergy destruction and performance of the process are studied. Results show that CNG pressure, pressure after Joule?Thomson valve, and temperature of CNG after heat exchanger of refrigerating system have significant effects on optimum ...

Cold exergy recovery during LNG regasification through a closed Brayton cycle
The liquified natural gas (LNG) regasification process is a source of cold exergy capable of being recovered for the exploitation of energy conversion. This paper presents a novel power plant structure that makes use of the LNG regasification process to increase the energy and exergy efficiency. The power plant consists of a closed Brayton cycle (CBC) fuelled by the flue gas released by the ...

Influence of reference temperature on exergy and exergoeconomic performance of a natural gas fired thermal power plant
The influence of reference temperature on exergy and exergoeconomic performance parameters of a thermal plant was investigated. The plant was simulated using HYSYS (2003) process simulator software and the exergy and exergoeconomic analyses were done using Microsoft EXCEL spreadsheet. As reference temperature increased from 15°C to 35°C, exergy efficiency decreased from 11.7% to 11.5% and ...

Production of synthetic gasoline and diesel fuels by alternative processes using natural gas, coal and biomass: process simulation and economic analysis
The problem of producing synthetic liquid fuels by alternative routes is addressed. Industrial processes known as Gas To Liquid (GTL), Coal To Liquid (CTL) and Biomass To Liquid (BTL) are considered: they use natural gas, coal and biomass as feedstocks, respectively. By means of process simulation, it is shown that the fuel produced on a weight basis per unit of feedstock (natural gas, coal and ...

Feature: Permian oil producers have a natural gas problem
A natural gas bottleneck in the Permian Basin could force oil producers to shut wells or seek waivers to flare large amounts of natural gas if takeaway capacity does not catch up by the end of this year. Lack of natural gas pipelines could impact oil output Producers may seek to expand flaring to keep oil flowing Citi says severe glut could send Waha gas price to zero Texas Railroad ...

Industrial Maintenance for Compressor Stations
Transporting natural gas via pipelines is very safe and cost-efficient. However, in order for the transportation process to work properly it is imperative that the natural gas be kept at the correct pressure. To accomplish this compressor stations are needed at regular intervals. Let’s take a look at some key components of compressor stations as well as industrial maintenance needs. The ...

Where To Find Money In Biogas
On the surface, wastewater treatment operations don’t appear to be handling precious material. But these facilities are actually processing a great deal of value every day. Sludge, a byproduct of wastewater treatment, turns out to be an entity worth cherishing. “Depending on treated sludge quality, the final product can be land applied, landfilled, incinerated, or composed,” ...

New York governor pauses `fracking`
New York Gov. David Paterson has signed an executive order halting the controversial natural gas drilling process called hydraulic fracturing until July 1. The process --- also known as "fracking" -- has come under scrutiny because of its alleged harmful effects on underground drinking water and the environment -- although industry leaders have insisted it's safe. The governor's order -- which ...

Landfill gas, canola and biodiesel: working towards a sustainable system
Snohomish County in western Washington State began converting its vehicle fleet to a blend of biodiesel in 2005. As prices for biodiesel rose due to increased demand for this cleaner-burning fuel, Snohomish County looked to its farmers to “grow” this fuel locally. Suitable oil seed crops for biodiesel feedstock include canola, mustard and camelina. The residue, or meal, has high value ...

Syngas monitoring - Purpose of gas monitoring in DRI plant
The use of process gas online monitoring systems at locations such blast furnace gas outlet, converter off gas exhaust and coking gas outlet is very reasonable in order to analyse the fuel gases composition by measuring the concentration of CO, CO2, O2, N2, CH4, and H2. There from the calorific value BTU and the Wobbe Index WI can be accurately calculated. Modern steel plants uses dedicated ...

Understanding the exergy of cold: theory and practical examples
Exergy analysis is used to evaluate the thermodynamic performance of processes, including energy conversion and supply systems. This often involves the calculation of the exergy of heat, at a temperature either above or below the environmental temperature (T0). The exergy of 'cold', i.e., heat at T Keywords: exergy of cold, cool exergy, exergy analysis, exergy factor, cool exergy potential, ...
