Vapor Liquid Equilibrium of Aqueous Diethanolamine Solution for Carbon Dioxide Capture Processes

نویسندگان

چکیده

Objectives : Acid gases such as carbon dioxide (CO<sub>2</sub>) and hydrogen sulfide (H<sub>2</sub>S) that cause global warming are mainly generated in chemical processes. As a technology for reducing acid gas, the post-combustion capture process is representative. Aqueous alkanolamine solution, which used absorption process, most representative absorbent. Thermodynamic data of vapor-liquid equilibrium important economics design operation. In this study, water + DEA measured so DEA, secondary amine, can be it designing new process.Methods Vapor-liquid mixture (diethanolamine) were under isothermal conditions 393.15 K using HSGC (Headspace Gas Chromatography).Results Discussion The correlated NRTL, an activity coefficient model. addition, additional thermodynamic absorbent mixture, density aqueous was at temperature 303.15 to 333.15 meter (Anton Paar DMA4500). converted into excess volume, volume Redilchi-Kister-Muggianu equation. Using water+DEA data, expected cost operating

Encapsulated liquid sorbents for carbon dioxide capture.

Drawbacks of current carbon dioxide capture methods include corrosivity, evaporative losses and fouling. Separating the capture solvent from infrastructure and effluent gases via microencapsulation provides possible solutions to these issues. Here we report carbon capture materials that may enable low-cost and energy-efficient capture of carbon dioxide from flue gas. Polymer microcapsules compo...

Molecular model for carbon dioxide optimized to vapor-liquid equilibria.

A molecular model for carbon dioxide is presented, and the parameters of the Lennard-Jones sites, the bond length, and the quadrupole moment are optimized to experimental vapor-liquid equilibrium data. The resulting molecular model shows mean unsigned deviations to the experiment over the whole temperature range from triple point to critical point of 0.4% in saturated liquid density, 1.8% in va...

Materials and Processes for Carbon Dioxide Capture and Utilisation

Materials and processes for CO2 capture and utilisation are an essential part of a holistic approach toward a sustainable energy future. CO2 and energy are tightly intertwined as energy produced from fossil fuel combustion always generates CO2. A major environmental concern, CO2 could also become an invaluable resource for making carbon-based materials and chemicals, and a means to store energy...

Liquid - Vapor Equilibrium/Distillation

Background The volatility of a compound is its ability to change into a vapor, or to evaporate at a particular temperature and pressure. The normal boiling point of a liquid usually allows comparison of its volatility to other materials, with lower boiling points indicating greater volatility, but this may be affected somewhat by the presence of other materials. Comparison of the concentration ...
