For manufacturers of nitrogen generators, which are often medium-sized engineering companies, the membrane process constitutes an inexpensivealternative for customized, needs-based nitrogen production.
Positive attributes
Evonik was able to combine two positive attributes: first, the SEPURAN® N2 technology requires fewer membrane modules than alternative membrane systems to generate the required amount of nitrogen. Second, the process uses less air, which means that the upstream compressor can be build smaller. This not only reduces the overall amount of energy consumed in nitrogen production but also lowers the investment cost, much of which goes to the compressor. Another advantage is that the SEPURAN® N2 membrane module can be connected to existing compressed-air systems, which enables on-site production of the inert gas at low investment cost.
