Kinetics of absorption of carbon dioxide in aqueous piperazine solutions [PDF]

, 2006
In the present work the absorption of carbon dioxide into aqueous piperazine (PZ) solutions has been studied in a stirred cell, at low to moderate temperatures, piperazine concentrations ranging from 0.6 to 1.5 kmol m- 3, and carbon dioxide pressures up ...

Solubility of CO₂ in 2-Amino-2-methyl-1-propanol (AMP) and 3-(Methylamino)propylamine (MAPA): Experimental Investigation and Modeling with the Cubic-Plus-Association and the Modified Kent-Eisenberg Models

Separations, 2022
CO2 capture attracts significant research efforts in order to reduce the volume of greenhouse gases emitted from fossil fuels combustion. Among the studied processes, chemical absorption represents a mature approach and, in this direction, new solvents ...

Application of the penetration theory for gas - Liquid mass transfer without liquid bulk: Differences with system with a bulk [PDF]

, 2006
Frequently applied micro models for gas-liquid mass transfer all assume the presence of a liquid bulk. However, some systems are characterized by the absence of a liquid bulk, a very thin layer of liquid flows over a solid surface.

The influence of acoustic power on chemical absorption of CO2 using Slow Kinetic Solvent [PDF]

E3S Web of Conferences, 2021
Ultrasonic Irradiation (UI) is an emerging technology that is used to assist the CO2 absorption process. Even for the slow kinetic solvents without using any chemical promoter, high-frequency UI might enhance mass transfer during the absorption process ...

An exhaustive review of carbon dioxide capture through the utilization of chemical solvents via absorption [PDF]

Engineering and Technology Journal
The release of carbon dioxide from the combustion of fossil fuels and chimney emissions has emerged as the primary catalyst for global warming. The significant increase in emissions is due to various factors, including power plants that rely on fossil ...
