    Modelling of a Gas Absorption Column for CO2-NaOH System under Unsteady-State Regime
    (Leonardo Electronic Journal of Practices and Technologies, 2008-01) OLUTOYE, Moses Aderemi; ETERIGHO, Elizabeth Jumoke
    The research work on the unsteady state behaviour 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 concentration, and tank volume, were constant. Model equations were derived for the time dependent parameters and the model compared with experiments conducted for duration of 90 minutes showed that 0.2 gram mole/litre of NaOH solution reacts with CO2 to give 0.1 gram mole/litre of Na2CO3.This clearly shows that the results of experiments conducted were in agreement with the model results
