The plant is shut down today. Could you advise on the precautions to take during the process of introducing hot hydrogen along with oil, as well as during constant-temperature hydrogen removal? Temperature control point: Why is this temperature controlled?
What temperature do you set for the circulating hydrogen with oil? Generally, it should be below 230°C; pay attention to the hydrogen sulfide concentration in the circulating hydrogen! Prevent over-reduction!
The pressure was maintained at 6.0 MPa, the temperature was kept constant at 200–230 degrees Celsius, and the cycle continued for 36 hours
