Neutralization of Chlorine in a Scrubber

Application ID: 1401

This example studies the kinetics of the neutralization of chlorine gas in water solution. The model assumes that the fluid volume is perfectly mixed and constant. This means that the chlorine has dissolved to an almost saturated state (1·10-2 mol/m3) and that the hydroxide has also mixed well throughout, as would be the case for a very small amount of fluid in a scrubber.

The study allows investigation of the time-scale of the reactions and the concentrations of the resulting products. A study of this type can be useful to determine the amount of hydroxide required to neutralize the chlorine and for sizing of a chlorine scrubber.

The model illustrates the usability of the Reaction Engineering interface available in the Chemical Reaction Engineering Module to study chemical processes involving several equilibrium reactions.

This model example illustrates applications of this type that would nominally be built using the following products:
