The pressure at the top of the stripping tower is 0.14 MPa, and the temperature at the top is 120°C. The pressure in the reflux tank is 0.13 MPa, while the temperatures at the bottom of the tower are 129°C, 131°C, and 140°C. It has been tested that the higher the temperature, the worse the performance indicators become, and the more unacceptable the conditions are. The feed rate is 8 Nm3/h, while the designed feed rate is 18 t/h. The above are the operational data
The pressure in the reflux tank is high; it’s usually between 60-80 kPa. High temperature and low pressure are favorable for the dissociation of hydrogen sulfide
