A model is described which may be used to simulate a packed column for countercurrent gas‐phase controlled absorption with liquid‐phase reaction. The model consists of a number of continuous stirred‐tank reactors in parallel with equal volumes and mass transfer areas. A distribution is presented which uses one parameter to determine the fraction of total liquid throughput going to each reactor. The model successfully predicts all responses, including those of K g a versus time for no reaction, K g a versus inlet acid normality, and K g a versus inlet gas concentration for liquid‐phase reaction for the systems ammonia‐water and ammonia‐sulfuric acid. It also explains the increase in mass transfer obtained by pulsing and controlled cycling.
