A newly developed microwave plasma system for fuel reforming was tested for three different hydrocarbon fuels. The microwave plasma system was powered by a low cost commercial magnetron and power supply. The microwave power was delivered to the nozzle from the magnetron via a coaxial cable,...

The exergy analysis method was applied in order to evaluate the new combined cycle proposed by Goswami [Solar thermal technology: present status and ideas for the future. Energy Sources 1998;20:137–45], using Hasan–Goswami–Vijayaraghavan parameters. This new combined cycle was proposed to...

This paper studies a gas-steam combined cycle system with CO2 capture by integrating the MCFC (molten carbonate fuel cell). With the Aspen plus software, this paper builds the model of the overall MCFC-GT hybrid system with CO2 capture and analyzes the effects of the key parameters on the...

In order to reduce CO2 emissions from a power plant, CO2 can be captured either from the syngas that is to be burned or from the flue gases exiting the energy conversion process. Postcombustion capture has the advantage that it can be applied to retrofit existing power plants. In this paper the...

In this paper the authors compare monoethanolamine (MEA) to aqueous ammonia (AA) and a solvent mixture of aqueous ammonia and ethanol (EAA) with respect to their post-combustion CO2 capture performance and their environmental impact. Simulation of all processes was carried out with Aspen Plus®...

The pre-combustion carbon capture technology based on coal gasification or methane reforming followed by (water gas shift reactors assisted with Pd-alloys membranes) WGS-MR is considered very promising for the production of a rich hydrogen stream that can be combusted in combined cycles....

The Aspen Plus process simulation package is used to evaluate the characteristics of the four-step Cu–Cl thermochemical water splitting cycle in terms of energy and exergy, to support the ultimate development of a pilot plant. Alternative designs for the heat exchanger network using Aspen...

This study evaluates the potential for reducing life cycle greenhouse gas (GHG) emissions of biomass gasification-based methanol production systems based on energy balances. Configurations which are process integrated with a chemical cluster have been compared to stand-alone units, i.e. units...

A systematic analysis of interrelations between different process steps in the biomass gasification and methanol synthesis chain was made. The energy performance of the system is assessed by reviewing previous studies and analysing a case study. Implications of technology choices and process...

The gasification technology has been object of study of many researchers, especially those involved in promoting large-scale electricity generation in sugarcane mills. This paper presents a simplified model for the gasification process based on chemical equilibrium considerations. The model...
