Embodiment
[0031] A SWSR-8 pressurized sulfur recovery process, comprising the following steps:
[0032] The acid gas enters the sulfur making furnace and is burned in the sulfur making furnace, and about 68% (v) of H in the furnace 2 S undergoes a high-temperature Claus reaction to convert sulfur, and the remaining H 2 1 / 3 of S is converted to SO 2 , The air required for combustion is supplied by the blower of the sulfur furnace.
[0033] The high-temperature process gas discharged from the self-made sulfur combustion furnace will generate 4.5MPa saturated steam through the sulfur waste heat boiler, and the temperature will drop to 350°C and enter the first-stage sulfur condenser to cool to 160°C. The condensed liquid sulfur will be separated from the process gas and flow out from the bottom into the sulfur-sealed tank. According to the reaction temperature requirements, the process gas is heated to about 240°C by the primary heater and enters the primary converter. Under the action ...
