How to adjust when the hydrogen sulfide-enriched gas concentration 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 enrichment 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 stages. 5. Increase the system temperature appropriately, provided that product quality is maintained.
