Ammonia Cracking Hydrogen Generation Plant Purification System 20-5000Nm3 / H

1. Technical chart

Hydrogenation of N2 purification equipment is the pressurize H2 which after normal purity and ammonia decomposition ,after the matching and mix into hydrogen and nitrogen purification equipment,the O2 and H2 in normal purity nitrogen exchange to water after reaction,then after cooling remove the water,pass through the cooling dryer in to the dryer device ,Then pass through the dust filter remove dust to make high purity N2,purity can be more than 99.999%,dew point ≤-60℃,nitrogen capacity 150Nm³/h,pressure 0.5Mpa can adjust.

2, TYH150-99.999 technical details

1. Normal nitrogen pressure: 0.6MPa( inlet pressure)

2. Nitrogen purity : ≥99.999%(O2 content ≤10PPM)

3. Nitrogen outlet pressure : 0.55MPa( adjustable)purification system pressure decrease 0.05 MPa

4. Dew point : ≤-60℃( normal pressure)

5. H2 content : Not limited

6. N2 consumption : 5-7%

7. Hydrogenation type : automatically

3, TYH150-99.999 working principle

Hydrogenation deoxidize purification technics,require the purity of nitrogen is 99%,pressure 0.6Mpa,rate of flow is 165 Nm3/h.The normal purity N2 and the H2 which controlled by flow meter inlet static mixer doing mixed,then inlet deaerator deoxidation,the outlet gas will pass through H2,guide to cooling device cooling to normal temperature,then guide to adsorption dryer,can remove CO2 and water,save the gas consumption(consumption between 5-7%).then pass through the dust filter can reach purity 99.999%,out put 150Nm3/h, output pressure 0.55Mpa,normal pressure dew point －60℃

III.  Ammonia decomposition making hydrogen system

This system is use liquid ammonia as raw material,let the liquid ammonia steam ,the gas state ammonia in the decomposing furnace high temperature accelerance layer separate to 75% H2 and 25% N2,the purification device remove the water in the gas. Because of liquid ammonia producing technique,the O2 content in the ammonia is very small, during high temperature accelerance layer,the less O2 have been reacted with H2,the O2 content can reach the ≤1ppm,accelerance layer in decomposing furnace,and the adsorber in the purification device degree can be more higher than production target,the system is sealed. We adopt two tower exchange working,can supply gas continuously. Adsorption tower use inside and outside drum-type structure,to avoid the CMS frit in high temperature,assure the CMS usage life.

We use low pressure ammonia decomposition,equip membrane type H2 booster,can make the H2 pressure 0.05Mpa,use membrance type H2 booster can let the H2 pressure reach 0.8Mpa,supply into H2&N2 mixer.
