We use air as raw material and carbon molecular sieve (CMS) as absorbent. Under A certain pressure, the amount of oxygen absorbed by CMS in the air is much greater than the amount of nitrogen absorbed by CMS. Therefore, the automatic pneumatic valve controls the switch to make tower A and tower B work alternately to realize pressure adsorption and decompression desorption, and complete the separation of adsorbent. Oxygen and nitrogen and achieve the target purity of nitrogen.
The SPNM 30-3000 series is the superior modular nitrogen generator of Since Gas, with excellent performance and comprehensive supply range. It adopts pressure swing adsorption technology (PSA) to obtain high purity nitrogen at normal temperature, the purity can reach 95% to 99.99%. Suitable for oil tanker, LPG/LNG tanker, dual fuel tanker, refueling barge, PSV/FPSO vessel, VLOC ship, offshore platform, ballast water treatment system and other ships. With more than 20 years of technical background and long-term market work in the gas industry, Since Gas has successively obtained the CCS Classification Society factory certification, BV Classification Society factory certification, ABS Classification Society Marine nitrogen system certification, and has provided gas generation solutions for CNOOC, Hudongzhonghua and other leading customers in the shipping industry, with a cumulative service of more than 500 ships.
Compressed air is used as raw material to enter one or more membrane components, each of which is composed of millions of hollow fibers, and various gases in the air (about 78% nitrogen, 21% oxygen, and 1% argon) are filtered out through the membrane wall with different penetrations, resulting in dry nitrogen, which is discharged from the end of the membrane to the gas point.
