Greenhouse gases emission is known as the main factor of climate change, and carbon dioxide (CO2) makes up vast majority of them. Carbon capture and storage (CCS) is a vital technology to mitigate industrial CO2 emissions, which is mainly generated in power plants. Currently, post-combustion capture based on aqueous amine scrubbing is considered as the most suitable technology for CO2 capture. ...

This paper reports a modelling work on the existing experimental data of single coal particles combustion process [1,2]. Two kinds of coal particles (a high-volatile bituminous coal / a lignite coal) are injected in a drop-tube furnace, ignited and burned in quiescent O2/N2 and O2/CO2 atmospheres with oxygen mole fraction varying from 20% to 100%. Ignition delay time, particle life time and par...

The reactor performance of two novel fluidized bed membrane reactor configurations for hydrogen production with integrated CO2 capture by autothermal reforming of methane (experimentally investigated in Part 1) have been compared using a phenomenological reactor model over a wide range of operating conditions (temperature, pressure, H2O/CH4 ratio and membrane area). It was found that the methan...

this study investigated different concepts for natural-gas-fired power plants with the co2capture, and compared them based on the net plant efficiency and emission of co2. the cycles were based ona six oxy-fuel, one post-combustion and two pre-combustion capture concept. this paper presented theresults of an environmental evaluation performed by the application of the life cycle analysis (lca) ...

In this work, CO2 capture by post-combustion using MEA is considered. The mechanistic model for the absorption process is elaborated and includes specie and energy balances for the liquid and gas phases. Model predictive control is implemented as a control strategy for the absorption column.

An important development in recent years has been increased interest in retrofitting CO2 capture at existing power plants. In parallel, it has also been suggested that flexible operation of power plants with CO2 capture could be important in at least some jurisdictions. It is likely that retrofitted power plants could have significant ‘built-in’ flexibility, but this potential is often not cons...

Climate change occurs as a result of absorption of infrared radiation which heats the atmosphere. Greenhouse gas emissions can increase the earth’s average temperatures since the majority of greenhouse gases are carbon dioxide (CO2). Fossil fuels have historically played a major role as the world’s primary source of energy and will continue to assume that role for at least the next few decades....

Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherent to the process and thus no energy is expended for the separation. Natural or refinery gas can
