It is desired to carry out the separation of a gaseous mixture that enters an absorption column with 4.8% of the component of interest and will be reduced to 0.5%. The system follows Henry's Law: y * = 0.15x. The washing of the gaseous mixture is performed with pure water which has a flow rate 5 times lower than the solvent gaseous flow of the mixture. Estimate the number of theoretical stages required to perform the operation.
