Mobile nitrogen gas generator for grain depot with nitrogen purity
99.5%
Nitrogen is normally used as protective gas or atmosphere gas for
reduction and carburetor. Under-circumstance of room temperature
and high pressure, oxygen and nitrogen are separated by
different-diffusion rate in CMS.Nitrogen purity and output volume
is adjustable to meet customer’s requirements.
PSA technique (Pressure Swing Adsorption, PSA for short):it's a
kind of advanced gas separation technology, based on physical
adsorption of gas molecule on the internal surface of adsorbent
(porous solid substances), using adsorbents in the same pressure
easy to absorb the high boiling point gas, difficult to absorb low
boiling point gas, and under high pressure adsorption amount of
absorbed gas increases, under low pressure adsorption of absorbed
gas to reduce the features to achieve gas separation. This process
under pressure adsorption of impurities, under reduced pressure
adsorption of impurities, make the adsorbent regeneration, is the
PSA cycle.
Nitrogen is normally used as protective gas .
Oxygen and nitrogen are separated by different-diffusion rate in
CMS.Nitrogen purity and capaity can be adjustable to meet
customer’s requirements.

Operational Principle of PSA Nitrogen Generation:
PSA nitrogen generation adopts carbon molecular sieve as adsorbent
whose capacity of adsorbing oxygen is larger than adsorbing
nitrogen. The two adsorbers (a&b) alternately adsrbing and
regenerating to separate oxygen from nitrogen in air to obtain
purified nitrogen by Auto-operated valves controlled by PLC.
Typical application:
Nitrogen is used in the surface of storage liquid and marine
engineering as protective gas. Using nitrogen to blow and sweep
containers, pipelines, reactors and isolation rooms. Nitrogen is
used in synthetic fiber spinning, wiredrawing anti-chlorination,
equipment anti-corrosion, paint, preventing polymerization during
the oil drying. Nitrogen is also used in oil tanker as protective
gas (the surface of oil is sealed and cleaned by nitrogen.).
Nitrogen can be used in dry quenching, catalyst regeneration, oil
fractionation, nitrogen fertilizer raw materials, catalyst
protection, washing gas, rubber packaging and storage, tire
production etc., nitrogen pressure injection oil drilling and so on
