Issues related to starting up the gas separation unit after maintenance
Thread Content
I started the machine without carrying out maintenance on the gas separation unit. What is the general procedure for starting the machine after maintaining the gas separation unit? Is steam purging still needed? Is it still necessary to fill with nitrogen for pressure testing and leak testing after purging? Also, does the system need to be purged of air before introducing liquefied gas? Please share how you operate it, thank you
A single explanation for this series of problems is the lack of understanding of the production principles of the equipment. 1. It is necessary to establish the unit’s operating procedures in accordance with the instructions provided by the unit itself or the equipment manufacturer. 2. Why use steam purging? 3. Why is pressure testing necessary, and why is nitrogen used for pressure testing? 4. Why remove the air? Additionally, should relevant follow-up actions be established for the areas involved in the maintenance work??? For newly installed equipment, it is necessary to obtain the operation manual from the design institute and the equipment manufacturer. If you are a new employee, it is best to consult the technical staff around you. For reference.
