Advanced process flow directly reduces compressed air consumption
The energy-saving CMS nitrogen generator provided by CAN GAS adopts unequal pressure equalization process．This process changes the lower pressure equalizing position.
equalizing air is gotten from the middle part of adsorption finished
tower and enters the bottom part of desorption finished tower to
equalize pressure. The inverted pyramid structure of nitrogen purity
ensures nitrogen with higher purity to be equalized from adsorption tower to desorption tower，which realize the Original bedding purity ladder structure distribution．
This process improves desorption tower nitrogen purity and reduces CMS oxygen pre-adsorption in the
desorption tower and increases CMS utilization ratio，i．e，increases carbon molecular sieve nitrogen production rate．Compared with equal pressure equalization process，unequal pressure equalization process is more reasonable，scientific and mature．Direct effect is the increase of nitrogen recycle rate and nitrogen production volume，indirect benefit is energy-saving．With these designs mentioned above，EES process not only improves nitrogen recycle rate and carbon molecular sieve utilization ratio，but also changes the history that no ppm class high purity nitrogen can be produced by PSA technology.
The higher nitrogen purity，the more energy-saving
Nitrogen Generation Process：clean compressed air flows inter tower A，when passing through the carbon
molecular sieve，oxygen，carbon dioxide，water and other contaminants are adsorbed，allowing nitrogen flows out as product gas CMS in tower A becomes saturated as time goes by．Then tower A stops adsorption and compressed air enters tower B to adsorb oxygen and produce nitrogen．Meanwhile，CMS in tower A begins regeneration，Two towers make alternate adsorption and regeneration to separate nitrogen from air and continuously produce nitrogen.
CAN GAS has been cooperating with world famous molecular sieve manufacturers for more than ten years．CAN GAS
can provide the most energy-saving products according to customers working condition．For some latest foreign
components，CAN GAS has obtained the sole purchase right in China．
Load adaptation is a new concept developed by CAN GAS in its PSA system R&D experiences．It is the achievement of CAN GAS technical engineers based on many years simulation experiments and repeating demonstrations．Under the circumstance of air consumption decrease，load adaptation realizes energy consumption reduction by prolonging adsorbing circulation period and realizes extra energy-saving in typical load range．
The most reliable air cleaning process ensures adsorbing efficiency and lifetime of molecular sieve
molecular seve(CMS) is the core in PSA nitrogen generator．Oil poisoning
is one of the main reasons for carbon molecular sieve invalidation．The
adsorption of water reduces CMS’s oxygen adsorption capacity．Compressed
air generated by oil lubricant air compressor contains oil and
water，which must be removed before it enters oxygen/nitrogen separation
assembly．Air cleaning assembly consists of pipeline filter，refrigerated
dryer，precise filter，super precise filter，active carbon oil
eliminator，automatic drain valve and ball valve．
