Experimental Determination of Continuous Phase Overall Mass Transfer Coefficients Case Study: Kühni Extraction Column

The aim of this study is to explore the capability of subcritical methanol to reduce the acidity of naphthenic acids and to determine reaction kinetics for large-scale reactor design.The experiments were carried out in a 25 mL autoclave reactor (China) at temperatures of 70-120oC, Methanol Partial Pressures (MPPs) of 0.1-1.5 MPa, and reaction times of 0-60 min. The total...

Absorption of Carbon dioxide in Packed Column

The absorption of carbon dioxide into aqueous ammonia solution using packed column was investigated. The volumetric overall mass transfer coefficients (KGav) for CO2 absorption into aqueous ammonia solutions were evaluated over ranges of main operating variables , that is, upto 16kPa partial pressure of CO2, 61-214 m 3 /(m 2 .h) gas flow rate, 0.753.06 m 3 /(m 2 .h) liquid flow rate, 2%16% ammo...

Mass Transfer Modeling of CO2 Absorption into Blended MDEA-MEA Solution

In this research, the thermodynamics and mass transfer of CO2 absorption has been studied in a mixture of MDEA-MEA amines. A relation is presented for mass transfer flux in the reactive-absorption process. For this purpose, the effective parameters on the mass transfer flux were investigated in both liquid and gas phases. Then, using dimensional analysis with the Pi-Buckingham theorem, the effe...
