Guiding the replacement of carbon molecular sieve on site for 7sets PSA nitrogen producing unit

CHEMXIN 3 technicians went to Xian customer factory for guiding replacement new carbon molecular sieve from the old one on Apr. 23^th 2022. The nitrogen production is 1300 m3/h, and the nitrogen purity is required to be more than 99% for coal mine.

Normally, the replacement steps of carbon molecular sieve are as follows:

First: Open the valve ports at the bottom of adsorption tower A and Tower B, remove all the old carbon molecular sieves inside, and close the bottom valve port.

Second: Put some activated alumina into the two towers as the protective drying of carbon molecular sieve

Third: Using a vibrator for 10-15 minutes to fill up the carbon molecular sieve in the tower when put half of carbon molecular sieve into tower, then continue to fill it up and use the vibrator again to confirm that both towers are filled it up. Finally, seal up by the two layers of screen and brown pad, and place the two layers of screen again. At last close the tower to complete the replacement.

The total loading of 2 towers is 4.4 tons, we successfully completed the replacement in one day with each worker's efforts. Thank you for our customer supporting so we can quickly complete the installation. Your satisfaction is always our driving force.
