Gas Absorption With Chemical Reaction in Packed Columns

The multi-period optimisation of an amine-based CO2 capture process integrated with a super-critical coal-fired power station for flexible operation

“…The approach of Taylor and Krishna was followed to calculate the mass transfer coefficients (Taylor and Krishna, 1993), using Onda's coefficients for gas and liquid phase mass transfer coefficients and effective surface area (Onda et al, 1968). In Onda's work, the effective surface area per unit column volume, a e , with units of m 2 m −3 , is given by …”

Model uncertainty of interfacial area and mass transfer coefficients in absorption column packings

“…The model developed by Onda, Bravo and Fair (Onda et al, 1967, Wang et al, 2005 is widely used to determine the gas and liquid side mass transfer coefficients of random packings. The model is given as, For the gas side mass transfer coefficient,…”

Pressure modification index based on hydrodynamics and mass transfer effects for modeling of CO 2 removal from natural gas via absorption at high pressures

“…Over-estimation of the column height can be observed for effective interfacial areas using Rocha et al (1996) and Billet and Schultes (1999). On the other hand, the effective interfacial area correlation of Onda et al (1968) tends to under-estimate the column height. This might be due to the fact that this correlation is designed based on random packing at atmospheric pressure (Wang et al, 2006).…”
