Nitrogen Purity - Urgent
Nitrogen Purity - Urgent
(OP)
We are a batch chemical facility and purge and blanket with nitrogen. The nitrogen is generated with a nitorgen generator putting out a 99.5% purity with liquid nitrogen backup. Has anyone out there ventured to use a lower purity -say 98 % nitrogen.. We have a couple of proudcts that chemically will degrade so we will bring pure nitrogen to these tanks but we are looking at the safety aspects and it scares a lot of people to lower the purity.





RE: Nitrogen Purity - Urgent
Using this data, it's possible to draw the UEL/LEL envelope and then see with various N2 purities whether it's possible to get into the explosive region.
