What are the functions of medium-pressure nitrogen in hydrogenation units? Do things like medium-pressure nitrogen in the injection pump and compressors serve for purging purposes? Do they also have any role in ensuring airtightness? Experts, please explain it to me
It is primarily used for testing the airtightness of the system. In addition, in emergency situations such as a hydrogen supply interruption or an overheating of the reactor, as mentioned earlier, nitrogen is used to replace the circulating hydrogen, thereby allowing the heat from the system to be removed through the emergency venting system.
That’s right; nitrogen is generally used for displacement, airtightness, and dry gas sealing. Medium-pressure nitrogen serves to protect the catalyst in case of an accident.
