Abstract :
Due to high pollution of the Claus sulfur recovery units in oil refineries, more treatment of tail gas of sulfur recovery unit is needed. Sulfur recovery unit of a refinery in Iran had selected as a target unit and detailed condition of it had surveyed. According to different treating processes, environmental limitation and tail gas treating processes, amine- based hydrogenation process was selected as an optimum process for efficient removal of sulfuric components of tail gas. Finally, proposed process was simulated in HYSYS software and different specifications of the process were achieved.
