Abstract

Abstract:

The drying processes for ultra-low dew point nitrogen cylinder includes positive pressure replacement, vacuuming and purging. These processes were compared with each other, and the methods for calculating nitrogen consumption, vacuuming and gas filling time were provided. It was determined to use a combination of replacement, vacuuming and hot nitrogen purging to control the water content of nitrogen in the cylinder. It was verified through on-the-spot test that the dew point of nitrogen in the cylinder can meet the requirements of technical indexes.
