ANALYSIS OF THE REMOVAL OF H2S WITH IMPREGNATED ACTIVATED CARBON

A general mathematical model with its governing equations in dimension less forms has been developed to describe the removal of hydrogen sulf ide with impregnated activated carbon. An approximate relationship bet ween the sulfur capacity and the reaction time in a single carbon pell et is obtained, and criterion to ascertain the rate controlling step o f the process can then be deduced. In the meantime, the choice of the appropriate oxygen concentration and the principle to be followed are also described.
