Nitrogen Making machine Chemical Industrial Air Separation Plant

The Principles of PSA Nitrogen Generator

PSA( Pressure Swing Adsorption) is an advanced gas separation technology, based on the physical adsorption of the internal surface in the adsorbent to gas molecules, separating the gas by the characteristics of absorbing to the quantity of different gas in general pressure. The CMS (Carbon Molecular Sieve) is a sorbent picked up from the air, used in separating Oxygen and Nitrogen molecular. The absorption quantity of CMS is greatly higher for Oxygen than Nitrogen under the same pressure.

. PSA Nitrogen Generator produces N2 gas, using air as raw materials and carbon molecular sieve as adsorbent, by the selective adsorption of carbon molecular sieve to O2 and N2, achieving the separation of the N2 and O2 in the air.

. It's easy installation & maintenance and more popular for Nitrogen requirements.

Air Separation Plant (ASU) adopts molecular sieve air purification, booster turbine expander, medium pressure air cycle refrigeration, double rectification column, full liquid air separation. The control and interlock of complete set plant will be operation in DCS or PLC system, the process will follow the most advanced and common international regulation, and design module on the premise of stable running. The Air Separation Plant including: air filtration system, air compressor system, air pre-cooling system, molecular sieve purification system, double rectification column system, liquid products storage system(if liquid products), instrument control system, electric control system etc.

Air Separation Plant technique is using air as raw materials, through gas expansion refrigeration precess to liquefaction of atmospheric air ,and separate Oxygen,Nitrogen and Argon from air, and obtains oxygen,nitrogen, argon products from air.

Product Application

Widely used in manufacturing the hydrogen and nitrogen at protective atmosphere. Especially for metal heating treatment ,powder metallurgy electronics and others heating.as a ammonia decomposition furnace, it can make hydrogen and nitrogen as protective atomosphere in non-ferrous metal, silicon steel, chrome steel and stainless steel and other metal materials and parts it can be used in bright annealing, in silicon steel it plays a role in decarburization ,in iron processing base powder metallurgy etc.

Equipment Warranty and After-sales Service

Hengda provides the device hardware warranty for one year, the shelf life from the date of acceptance of the equipment is 12 months or 18 months receiving goods, according to which date arrive first. During the period of shelf life, any defects, faults and damage caused by our design, craftsmanship, manufacturing or material defects and any issue caused by our company shall be handled by us without any charge. In the period of quality shelf life, it is free to supply and replace the equipment and spare parts which are not damaged by demand-side. If the equipment have any failure in the operation, supplier’ professional personnel will hurry to the scene within 24 hours when receiving the notice that the demand-side can’t solve the failure. And beyond of shelf-time, Hengda will annual tracking the quality regularly, checking the condition of the equipment operation and also can provide the spare parts long-term.
