Application of high efficiency compound desulfurizer in sulfur solvent regeneration unit
This paper introduced the application of YXS-202 high efficiency compound desulfurizer in 350 t/h solvent regeneration unit of sulfur recovery unit in a petrochemical company.Considering the problems such as the large circulation amount caused by the use of domestic ordinary desulfurizer in the sulfur plant,the long-term high steam energy consumption of the solvent regeneration unit,the high H2S content at the exit of the exhaust gas absorption tower of the sulfur recovery plant,the high SO2 content of the flue gas emission,and the serious accumulation of sulfur powder in the CTS unit reactor,etc.,through the application of highly efficient compound desulfurizer YXS-202,it realized the conditions of saving 0.4 MPa steam more than 20%,reducing more than 70%H2S content at the outlet of the tail gas absorption tower,greatly improving the sulfur powder accumulation in the CTS reactor,which had significant effects on energy saving and consumption reduction,long cycle operation and ultra-low SO2 flue gas emission,and provided a reference for the selection of desulfurizer in similar units.
