【Q&A Question 013】January 13, 2018: What is the purpose of filling the distillation system with N2? Using N2 filling enables safe and reliable airtight sealing, purging, and cleaning of related equipment and pipelines ； It can be used as an air seal to prevent contact between air and oil, as well as contact with related equipment, thereby ensuring safety ； Pressurizing at startup can accelerate the increase in system pressure, achieve liquid level balance, and shorten the startup adjustment time. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limitations on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.

Establish pressure in the tower; use the pressure difference to push the medium into the next container (usually no bottom pump is used)
Using N2 can ensure safe and reliable airtight sealing, as well as the purging of related equipment and pipelines; it can serve as an air seal to prevent contact between air and oil products as well as with related equipment, thereby ensuring safety. Pressurizing the system at the start-up stage can accelerate the increase in system pressure and achieve liquid level equilibrium, thus reducing the time required for startup adjustments.
