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...
متن کاملWater-gas shift (WGS) operation of pre-combustion CO2 capture pilot plant at the Buggenum IGCC
In the Nuon/Vattenfall CO2 Catch-up project, a pre-combustion CO2 capture pilot plant was built and operated at the Buggenum IGCC power plant, the Netherlands. The pilot consist of sweet water-gas shift, physical CO2 absorption and CO2 compression. The technology performance was verified and validated models were obtained. This paper describes the validation of a WGS reactor model and the excel...
متن کاملEnergy Savings Potential through Waste Heat Recovery from Flue Gas for Post Combustion Co2 Capture
Flue gas from a plant using fossil fuels contains CO2. Thus power/process plants using fossil fuels contribute to climate change if CO2 in flue gas is not captured. The process of CO2 capture from flue gas is called „postcombustion‟ CO2 capture. Existing plants may be retrofitted with this process to minimize CO2 emission. Amine solutions are mostly used for this process to scrub the flue gas. ...
متن کاملPebax-Modified Cellulose Acetate Membrane for CO2/N2 Separation
Carbon dioxide (CO2) release from the exhaust gas streams of power plants that burn fossil fuels contributes the most emission of this gas, which includes more than half of the greenhouse effects. Thus, the separation of CO2 from exhaust gases is one of the main environmental concerns. Membrane technology, due to many advantages, has attracted many research attentions among the various gas sepa...
متن کاملCO2 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,...
