Optimal location for dry gas injection in the desulfurization system

This is an anthracene oil hydrogenation unit; the dry gas produced enters a dry gas desulfurization system, where liquid ammonia is used to absorb hydrogen sulfide from the dry gas. I would like to know whether it is more effective to inject the liquid ammonia into the aqueous phase or into the gaseous phase for better absorption
Of course, it is injected into the gas phase; liquid ammonia is fed in from the top of the tower, while dry gas enters from the bottom.
