CO 2 chemical absorption into aqueous solutions of piperazine: modeling of kinetics and mass transfer rate

Optimization of production conditions for synthesis of chemically activated carbon produced from pine cone using response surface methodology for CO2 adsorption

“…1,2 Many efforts have been done to develop various techniques for CO 2 removal including chemical absorption, physical absorption, physical adsorption, membrane separation, and cryogenic separation. 3,4 Among the various chemical and physical processes available for CO 2 removal, using aqueous solution of alkanolamines such as monoethanolamine and diethanolamine based absorption method is well known with signicant commercial application for CO 2 capture. 5,6 However, some drawbacks associated with liquid amine solutions for CO 2 separation such as extensive corrosion of equipment, high cost of amine, oxidative solvent degradation, large energy penalty for regeneration and loss of amine during regeneration are reasons which make it indispensable to see other alternative processes.…”

The effect of solid adsorbents in Triethanolamine (TEA) solution for enhanced CO2 absorption rate

“…The final equation obtained according to Eq. (12)(13)(14) is presented according to which the predicted values were obtained. As it is known, the numerical coefficients of temperature and TEA concentration are negative, which indicates the negative effect of these parameters, as well as the numerical coefficient of the amount of activated carbon, which shows the positive influence of this parameter on CO 2 loading.…”

“…Currently, chemical absorption of CO 2 with alkanolamines is the most common commercial method of high-efficiency separation in the industry. Chemical absorption by amine solvents is a reliable, well-established, and practical technique widely regarded as the most selective and promising of the various CO 2 removal technologies [12][13][14][15][16]. Conventional amine absorbents, on the other hand, have a significant energy demand for solvent regeneration.…”

Mass Transfer Flux of CO2 into Methyldiethanolamine Solution in a Reactive‐Absorption Process

“…Another advantage of MDEA is the low specific heat and heat of reaction with H 2 S and CO 2 , which reduces the energy consumption in the desorption process. By replacing DEA with MDEA, the energy consumption could be decreased up to 75 % [16,17].…”
