In the context of the liberalization of the European natural gas market former monopolists face a challenge to react to market opening by realigning their strategies. Three major groups of companies can be identified that are capable to influence the Europ ...
Gaseous fuels produced, for example, by waste or agricultural by-products fermentation (biogas) can be burned in-situ by cogeneration systems like spark-ignition internal combustion engines. However, the more and more stringent legislation for exhaust gas ...
THE ENVIRONMENTAL IMPACT OF NATURAL GAS VEHICLES The natural gas vehicle (NGV) presents one of the few options to current automobile related environmental problems that is both feasible with today’s technology and commercially viable. NGV technology is not ...
The energy efficiency of an industrial hydrogen production process using steam methane reforming (SMR) combined with the water gas shift reaction (WGS) is analyzed using process integration techniques based on heat cascade calculation and pinch analysis wi ...
Simulation of biodegradation of chlorinated solvents in dense non-aqueous phase liquid (DNAPL) source zones requires a model that accounts for the complexity of processes involved and that is consistent with available laboratory studies. This paper describ ...
Although the gas market in the European Union was opened up with two major directives in 1998 and 2003, competition in Europe is still developing slowly. One major cause is the insufficient availability of gas that is not contracted by long-term contracts ...
The gas push−pull test (GPPT) is a single-well gas-tracer method to quantify in situ rates of CH4 oxidation in soils. To improve the design and interpretation of GPPT field experiments, gas component transport during GPPTs was examined in abiotic porous me ...
The modelling of natural gas combustion with detailed as well as reduced kinetic mechanisms has been subject to many publications already. Most of the mechanisms are validated at higher temperatures and ambient pressures. Only recently - in parallel to a g ...
Nowadays, most of the natural gas conversion systems available on the market for bifuel vehicles are based on the venturi principle or on the continuous injection principle for the carburation of the engine. Even if the driveability of these systems is sat ...
