Help: Minimum boosting temperature. Urgent
Thread Content
The hydrogenation reactor has a normal operating pressure of 17 MPa. It has now been restarted after maintenance; nitrogen is circulating in the system. The wall temperature is in the high 50s degrees, the bed temperature is 170 degrees, and the system pressure is 4.46 MPa. (I remember the minimum pressure to be around 4.5 MPa.) Minimum boosting temperature 93). The required minimum pressure is almost reached, but the wall temperature has not yet arrived there. I’d like to ask everyone now whether there is a limit on the minimum boosting temperature under nitrogen conditions. (The voltage increase has now stopped, but the pressure rises slowly as the temperature increases.) ）
During MPT, in order to improve the toughness of the material and prevent brittle fracture caused by temper embrittlement and hydrogen embrittlement, even in a nitrogen environment, as long as it is not the first time the equipment is being used, H will inevitably remain in the vessel walls (even after degassing),; therefore MPT is still necessary.
