Experimental and theoretical investigation of an absorber-stripper pilot plant under nonequilibrium conditions

Abstract

An experimental and theoretical investigation of an absorber-stripper pilot plant for C02 removal has been performed under conditions where the exit gas and the liquid are not in equilibrium. The effect of all the operating parameters, liquid flow rate, steam flow rate, absorber gas flow rate, and pressure, has been investigated. A single graph of the absorber efficiency vs. the number of transfer units In the gas phase represents a very wide range of operating conditions.

CO2 capture with potassium carbonate solutions: A state-of-the-art review

“…A simple thermodynamic model presented by Astarita et al (1983) (see Section 4.2.4.2) for the gas treatment process has been applied in some non-equilibrium rate-based models for hot PC process; for example, in the works of Joshi et al (1981), Sanyal et al (1988), Rao (1990Rao ( , 1991, and Rahimpour and Kashkooli (2004). In addition, Suenson et al (1985), Marini et al (1985), and Todinca et al (2007) used a similar simple approach by unity activity coefficients. Rahimpour and Kashkooli (2004) developed a comprehensive model for the absorption of carbon dioxide into promoted PC solution by three types of promoters for comparing their effectiveness in carbon dioxide removal at identical operating conditions; DEA, MEA, and methyl amino ethanol (MAE).…”

Behaviour of absorption/stripping columns for the CO2‐MEA system; Modelling and experiments

“…Measurements in a laboratory scale column were well reproduced by their model. Suenson et al (1985) and Marini et al (1985) performed steady-state and dynamic modelling of an integrated gas absorber-stripper system in pilot scale packed columns, _ _ ~ *To whom correspondence should be addressed.…”
