What Is a Pressure Swing Adsorption (PSA) Nitrogen Generator?
PSA is a technology used to separate some gas species from a mixture of gases. The working principle of a PSA nitrogen generator is that under high pressures, nitrogen gas exhibits a strong affinity for adsorbent media such as zeolite or granular activated carbon. Moreover, various gases can be absorbed from a mixture at different rates, depending on the amount of pressure applied.
What is the difference between PSA and membrane nitrogen generator?
Is there a difference in production rate or gas purity between the two types of nitrogen generators?
Nitrogen Separation Membranes can typically produce nitrogen at purities up to 99.5%, while PSA nitrogen generators can achieve purities up to 99.9995%
What is inside of PSA Tower?
PSA technology utilizes two towers which are filled with carbon molecular sieve (CMS). Compressed air enters the bottom of the “online” tower and flows up through the CMS. Oxygen and other trace gases are preferentially adsorbed by the CMS, allowing nitrogen to pass through.
What is CMS ?
Carbon molecular sieve (CMS) , takes the appearance of cylindrical black solid, contains countless 4 angstrom fine pores. The main component is element carbon. It is a new and one of the few non-polar adsorbent that specializes in separating oxygen from nitrogen under the normal temperature and pressure, also it is an important part in natural gas processing.
How does carbon molecular sieve work?
CMS adsorbs oxygen gas, carbon dioxide gas, moisture and so on in compressed air in a short period of time and compressed nitrogen gas is available at the outlet. When the pressure decreases to the atmospheric or vacuum level, CMS which has adsorbed oxygen gas and others easily desorbs them and is regenerated.
What types of carbon molecular sieve do we have?
Xintao provide CMS220, CMS240,CMS260 and CMS280
There are different diameters to choose from 1.1-1.3mm, 1.3-1.5mm to 1.5-1.8mm etc.
Xintao Carbon Molecular Sieve, has the character of large N2 yield capacity and high N2 recovery. It has long service life, is suitable for various types of PSA nitrogen making machine.
