During residue hydrogenation, the recycle hydrogen compressor stopped due to low lubricating oil pressure, which triggered a series of interlocks; the feed pump, heating furnace, etc., also stopped, but they were restarted shortly thereafter. Question: How should the pressure in the reaction system be increased, and what should the rate be? I hope experts can give some advice.
In the residue hydrogenation reactor system, if the recycle hydrogen compressor shuts down due to low lubricating oil pressure, causing the entire system to stop operating, it is necessary to restart it and increase the pressure. When boosting the pressure again, it should be increased gradually to avoid equipment damage or safety hazards caused by too rapid pressure changes. Generally, the rate of pressure increase should be kept within 0.5 MPa per minute. At the same time, it is necessary to monitor the stability of temperature and pressure inside the reactor to ensure the proper operation of the system. The specific operation procedures should be followed in accordance with the equipment’s technical specifications and safety operation guidelines. .
