Energy Consumption Analysis of Cryogenic-membrane Hybrid Process for CO2 Capture from CO2-EOR Extraction Gas

A Physical Absorption Process for the Capture of Co2 from Co2-rich Natural Gas Streams

A new CO2/CH4 gas separation process is presented in this paper. Capture of CO2 from natural gas is carried out using an n-alkane solvent in a conventional physical absorption process. A methodology to find optimal process condition and solvent has been developed using an advanced equation of state (SAFT-VR), process modelling-optimisation software (gPROMS), and detailed process cost estimation...

Process simulation and optimal design of membrane separation system for CO2 capture from natural gas

In order to avoid carbon dioxide (CO2) built up in the atmosphere, the major source of global warming, CO2 capture must be applied to large point sources including natural gas processing. Membrane process, a relatively new technology among other available techniques, can be used for the purpose of CO2 capture from natural gas. Over the decades, the membrane performance has been described by dif...

A computational investigation on the structural features of alkanolamine solvents for CO2 capture process from power plant flue gas

CO2 Capture from Natural Gas Combined Cycles

CO2 capture from fossil fuel power plants is increasingly proposed for greenhouse gases emission mitigation. It can be applied to coal power stations (with boiler and steam cycle or with gasification) or to natural gas combined cycles (NGCC). The first case is probably the most important in a mid-term perspective, due to: (i) the larger amount of avoided carbon per unit of electricity produced,...

Simulation of Co2 Capture Process

Carbon dioxide capture process has been simulated and studied under different process conditions. It has been shown that several process parameters such as lean amine temperature, number of adsorber stages, number of stripper stages and stripper pressure affect different process conditions and outputs such as carbon dioxide removal and reboiler duty. It may be concluded that the simulation of c...
