PURPOSE: Provided is a method for improving distillation efficiency of hydrogen sulfide in an absorption solution regenerating tower for purification of cokes oven gas by adjusting pressure and temperature of the absorption regenerating tower to increase separation efficiency of hydrogen sulfide from carbon dioxide. CONSTITUTION: The method relates to a pyrogenic process for treatment of cokes oven gas generated in a cokes oven(100). The cokes oven gas is treated by an absorption solution regenerating tower(170) to send an absorption solution to a hydrogen sulfide collecting tower(110), an ammonia collecting tower(120) to collect ammonia and an ammonia distillation tower(180). The method includes the steps of providing an indirect heat source as a reboiler(1) using steam to readily adjust temperature and pressure in the absorption solution regenerating tower(170); supplying inert gas at a predetermined pressure to adjust pressure in the tower; and sending condensed water generated in the reboiler(1) to ammonia collecting tower(120).
