Please help me find out why the regeneration tower cannot evaporate hydrogen sulfide?
Thread Content
The regeneration tower is a packed tower with 5 trays and the second tray is fed. The feed temperature is 132°C, the pressure is 200Kpa, and the mass flow rate is 490218.5kg/h, of which hydrogen sulfide is 883.32kg/h, carbon dioxide is 722.78kg/h, water is 230.12kg/h, and NHD is 488376.3kg/h. Add reflux water to the top of the tower, 5000kg/h, the pressure is 101.35Kpa, and the discharge temperature is normal temperature.: top of tower: The temperature is 107.7°C, the pressure is 101.35Kpa, and the mass flow rate is 6365.29kg/h, including hydrogen sulfide 253.81kg/h, carbon dioxide 528.25kg/h, water 5004.56kg/h, and NHD 575.98kg/h. bottom of tower: The temperature is 147°C, the pressure is 101.35Kpa, and the mass flow rate is 488853.30kg/h, of which hydrogen sulfide is 629.51kg/h, carbon dioxide is 194.53kg/h, water is 225.55kg/h, and NHD is 487800.33kg/h. Why can’t hydrogen sulfide evaporate out? Please help! Thanks
The host can refer to this http://bbs.hcbbs.com/thread-273874-1-1.html Maybe it will help solve the problem
It is caused by many factors, such as low water content.
