How to adjust when the concentration of hydrogen sulfide-rich gas is low? 1. Check the nitrogen content in the gas and increase the flow rate accordingly; 2. Check the flow rate in the hydrogen sulfide concentration enhancement pipeline and increase the circulation volume as necessary; 3. Examine the distillation conditions and raise the temperature; 4. It is possible to slightly reduce the pressure in the other flash sections; 5. Increase the system temperature appropriately, provided that product quality is maintained.

Answer: (1) Check the nitrogen lift volume in section T61304Ⅱ and increase the flow rate appropriately. (2) Check the flow rate in the hydrogen sulfide concentration pipeline and increase the reflux gas volume as appropriate. (3) Check the distillation conditions in the second stage of the thermal regeneration tower and increase the temperature at the bottom of the tower. (4) The flashing pressure in the first stage of the thermal regeneration tower can be reduced appropriately. (5) While ensuring product quality, the methanol temperature in the system can be increased slightly.
