The system is low cost with long service life, simple operation, compact structure, small coverage and simple installation.
The system vaporizes liquid ammonia, and heats it with a catalyst until decomposition occurs, creating a mixture of gas consisting of 75% hydrogen and 25% nitrogen.
Based on the principle that the molecular sieve adsorbs ammonia and water at different temperatures, high purity gas is produced by heat regenerating through the mixture working at normal temperature.
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.
