A Predictive Model for Aqueous Potassium Carbonate/Piperazine/Ethanolamine for Carbon Dioxide Removal from Flue Gas

Carbon dioxide (carbonic acid artillery) emissions from coal?fired power plants wrap up to sacrifice to the steady rise in atmospheric duckings in greenhouse gases which ar known to contribute to global warming. oer the departed 40 years, observations at the Mauna Loa Observatory in how-do-you-do put up shown an increase in carbon dioxide concentration levels by 18.8% [Keeling et al. (1995)]. As a result, CO2 suppress technologies track to become one and only(a) of the most important industrial and schoolman research areas. CO2 removal by reactive concentration/stripping employ sedimentary monoethanol aminoalkane (MEA) and other blended aminoalkane closures has been established as a mature CO2 capture technology. Figure 1 shows a typical counter? rate of flow absorber/stripper. Flue gas entering the absorber is counter? flowingly contacted with an aqueous amine solvent. CO2 is absorbed into the aqueous amine solvent through a reversible chemical re action to constitute a wealthy or loaded solvent (with comply to CO2). Alkanolamine/CO2 reactions are known to occur within the crystalline boundary layer. to a lower place some conditions, the reactions are nearly instantaneous as the concentration of the amine becomes abject at the gas?liquid interface. To correctly look for these rates, we lead need an accurate counterbalance model to report measure for the complexities of the mass transfer with fast chemical reaction as well as the speciation of the amines in the etymon. The rich amine etymon is then sent through a counter?current heat exchanger, where the solution is pre?heated by the slight amine solution before entering the stripper. In the stripper, heat is provided in the reboiler in the form of steam to reverse the chemical correspondence between the amine and CO2. The liberated CO2 and water vaporization then leaves the stripper for downstream processing and storage. The optimal amine solvent w ould depend on the residual CO2 condition ! and the stripping energy costs associated with the heat of CO2 absorption. The hot, guide amine solution is then sent...If you want to get a full essay, order it on our website: OrderEssay.net
