This paper evaluates three acid gas removal concepts studied in the project “A Green Sea”. Two solvent concepts (aMDEA/MDEA and Selexol) and a low-temperature concept are modelled and assessed, taking different raw natural ...

This paper present the techno-economic assessment of an MEA-based CO2 capture from a cement plant and the importance of the steam supply on the costs. The evaluations present the energy performances of the CO2 capture ...

Natural gas (NG) is the fossil fuel with the lowest emissions of CO2 per kilowatt of energy produced. In the case of transporting the natural gas through pipelines, the CO2 specifications depend on each country but are ...

Developing “good” membrane modules and materials is a key step towards reducing the cost of membrane-based CO2 capture. While this is traditionally being done through incremental development of existing and new materials, ...

Four different post-combustion capture technologies are compared for the same NGCC (electric efficiency 58.1% without CO2 capture). The technologies are aqueous amine, polymeric membranes, a low temperature sorbent and ...

A novel hybrid concept is proposed, combining Pd-alloy membrane and low temperature separation technology, to produce pure H2 from gasified coal and capture the main part of the generated CO2. 75% of the H2 produced from ...

As an alternative to chemical and physical solvents, membrane technologies and PSA, process principles for CO2 removal from natural gas by low-temperature distillation are presented. A low-temperature process reducing the ...

Process synthesis methods have only recently been applied for the design of CO2 capture systems. At the crux of the CO2 capture process is a separation technology (sorbent, membrane or phase separation) applied to CO2/N2, ...
