DESULFURIZING METHOD USING PRESSURIZED WATER

摘要

PURPOSE:To remove H2S and SO2 in the simple treatment by sending both a gas contg. H2S and a gas contg. SO2 simultaneously and continuously into the pressurized water free form an additive and allowing both to perform the Claus reaction. CONSTITUTION:Both a gas contg. H2S and a gas contg. SO2 are sent into a reactor 1 charged with water free from an additive through the lines 2, 3 and the soln. in bubbled in the pressurization. The Claus reaction is made active together with passage of time and elemental sulfur is produced and made slurry. The slurry of sulfur is sent to a separator 5 through a line 4 to separate it into water and sulfur and sulfur is discharged through a line 6 and water after the separation is circulated to the reactor 1 through a line 7. After the desulfu rized gas removed with the large parts of H2S and SO2 is sent to a cooler 11 via a line 10 to condense and separate the accompanied steam, it is washed with water in a purification tower 13 to remove the nonreacted H2S and SO2 and discharged or recovered through a line 14.
