Carbon dioxide is a powerful greenhouse gas, whose massive presence in the atmosphere causes gradual global warming. Absorption by means of chemical solvents is the most commonly used process for CO2 removal. It can be applied to gaseous streams in power plants, natural gas, and refinery gas. Amine scrubbing is widely considered the most mature technology for PCC (post-combustion CO2 capture), and...
Carbon dioxide emission, one of the core cause of global warming and other threats of nonreversible environmental effects, is in focus today. Among the several methods of CO2 emission mitigation, post-combustion carbon capture (PCC), based on absorberdesorber systems with amine absorbents, is one of the promising alternatives. The major anthropogenic CO2 point sources are power plants, natural gas...
Energy consumption of distillation needs high portion of the total energy demand of the fuel-grade bioethanol production. Pervaporation, being a membrane separation process, is a promising alternative process to distillation. A detailed analysis was performed considering the energy demand of concentration of ethanol solution obtained during fermentation up to the fuel-grade quality applying both hydrophilic...
