Abstract
Abstract
Computational models have been developed and solved by the use of a computer coded software Python on Spyder console. The models were developed to gain an improved insight of carbon dioxide capture process performance by concentrating on the volume flowrate of the flue gas. The models were based on chemical absorption method. The study was aimed at exploring the absorption capacity of monoethanolamine (MEA), chilled ammonia and potassium carbonate (K2CO3) systems by concentrating on the movement of flue gas volume. The profiling of volume was prepared in order to see how much of the flue gas will be lost at the end of absorption when the three mentioned absorbent are used to capture carbon dioxide (CO2). The results showed that high volume flow of the gaseous phase has led to poor absorption, whilst low volume flow yields higher CO2 absorption. Moreover, in comparison to K2CO3 and chilled ammonia, the MEA was found to have the best absorption capacity.
