CO2 separation is an energy intensive process, which plays an important role in both energy saving and CO2 capture and storage (CCS) implementation to deal with global warming. To quantitatively investigate the energy consumption of CO2 separation from different CO2 streams and analyze the...

Global warming and climate change concerns have triggered global efforts to reduce the concentration of atmospheric carbon dioxide (CO2). Carbon dioxide capture and storage (CCS) is considered a crucial strategy for meeting CO2 emission reduction targets. In this paper, various aspects of CCS...

This paper illustrates a methodology developed to facilitate the analysis of complex systems characterized by a large number of technical, economical and environmental parameters. Thermo-economic modeling of a natural gas combined cycle including CO2 separation options has been coupled within a...

CO2 separation from wet and dry synthetic biogas has been investigated using adsorption on 4A and 13X molecular sieves in dynamic conditions, flowing through fixed beds in an adsorption column connected with an IR detector. The adsorption of CO2 has also been investigated by IR spectroscopy over...

In this paper, the results of the thermodynamic and economic analyses of distributed power generation plants (1.5MWe) are described and compared. The results of an exergetic analysis are also reported, as well as the thermodynamic details of the most significant streams of the plants. The...

Condensed Rotational Separation is a technique in which flue gas is cleaned by condensation of the CO2 and mechanical centrifugal separation. It requires partial purification of CO2 to concentrations above 50% in the flue gas, prior to separation. This purification can be realized with existing...

Three-reactor chemical looping (TRCL) is a hydrogen and electricity production technology with inherent separation of carbon dioxide by use of the iron-based oxygen carrier particles. In this study, an integrated continuous operation test unit (300Wth) using 20wt% Fe2O3/ZrO2as an oxygen carrier...

The membrane reactor is a novel technology for the production of hydrogen from natural gas. It promises economic small-scale hydrogen production, e.g. at refuelling stations and has the potential of inexpensive CO2 separation. Four configurations of the membrane reactor have been modelled with...

CO2 solubility in ionic liquids has been measured extensively in order to develop ionic liquid-based technology for CO2 separation. However, the energy consumption analysis has not been investigated well for such technology. In order to carry out the energy consumption analysis for CO2...
