What is the purity of the liquid nitrogen?

Liquid nitrogen purity is typically less than 3 ppm O2, depending on the specific model.

Does the plant require frequent maintenance of molecular sieves?

No, the expected molecular sieve life is around 25 years, which covers the whole life time of the nitrogen plant, so there are no replacement costs.
