Absorption of CO2 Gas by Perforated Plate Column

Modelling of a Gas Absorption Column for CO2-NaOH System under Unsteady-State Regime

The research work on the unsteady state behavior of gas absorption column for CO2-NaOH system was carried out using the armfield gas absorption column. A model equation was developed by considering material balance around the system. The concentrations of the inlet and outlet liquid streams and the gas outlet stream varied as functions of time, while all other parameters, gas inlet stream conce...

CO2 Capture from Flue Gas by Phase Transitional Absorption

Spaceborne estimate of atmospheric CO2 column by use of the differential absorption method: error analysis.

For better knowledge of the carbon cycle, there is a need for spaceborne measurements of atmospheric CO2 concentration. Because the gradients are relatively small, the accuracy requirements are better than 1%. We analyze the feasibility of a CO2-weighted-column estimate, using the differential absorption technique, from high-resolution spectroscopic measurements in the 1.6- and 2-microm CO2 abs...

Simulation of the Sieve Plate Absorption Column for Nitric Oxide Absorption Process Using Neural Networks

We present the modeling of the absorption column performance using feed-forward and radial basis function type neural networks. The input and output data for training of the neural networks are obtained from a rigorous model of the absorption column. The results obtained form the neural network models are compared with the results obtained mainly from the simulation calculations. The results sh...

Steady-State and Dynamic Simulations of Gas Absorption Column Using MATLAB and SIMULINK

Separation is one of the most important process in all the chemical industries and the gas absorption is the simplest example of separation process which is generally used for the absorption of dilute components from a gaseous mixture. In the present work, a dynamic system of mathematical equation (algebraic and differential) is modeled to predict the behavior of the absorption column using mat...
