Liquid ammonia hydrogen production technology
Thread Content
Let’s discuss the liquid ammonia hydrogen production technology. What scale is it suitable for? Is the investment large? Is the operating cost of the product economical (compared to hydrogen production via methanol cracking)? What level of purity can the product achieve? Which design firm has more mature technology? Are there any relevant technical documents available for reference?
Buy liquid ammonia to produce hydrogen? That will cost a fortune in compensation. This should only be suitable for testing, and not for industrial production.
Hydrogen production from liquid ammonia, that is, hydrogen generation through ammonia decomposition, can be used in industrial production. I have seen in person a company producing hydrogen through ammonia decomposition. At that time, I saw liquid ammonia tank trucks entering the construction site from time to time, and I also went to the hydrogen production workshop to take a look. Pretty big. As for the scale and purity, I didn’t inquire about them at the time because I’m not majoring in this field. As for comparing it with MC, I don’t understand that either. Wait for an expert to answer.
We plan to build a hydrogen production plant with a capacity of 300 Nm3/h and another with a capacity of 3000 Nm3/h. I’m wondering what the feasibility of using the ammonia decomposition process is
There is no issue with feasibility, but more demonstration is needed. Currently, more hydrogen is produced by methanol hydrolysis than by ammonia, as it seems to be more advantageous from a technical standpoint.
In the 1970s, France introduced three large fertilizer production plants; during startup, hydrogen was generated through ammonia cracking to raise the temperature, after which oil was used to produce hydrogen. Today, the technique of producing urea from oil has been largely replaced by methods that use coal as a raw material. Based on this, the ammonia-to-hydrogen process is considered feasible, with very low profits or essentially no profits at all.
Hydrogen production from ammonia is a last resort; ammonia is obtained by synthesizing hydrogen and nitrogen from chemical raw materials. Hydrogen is produced by the cracking of ammonia; so isn’t that going in circles again? Won’t the production cost increase as a result? So it is technically feasible, but not economically viable.
For equipment of your size, it is more appropriate to use water-gas or natural gas for hydrogen production; ammonia decomposition is suitable for smaller volumes of less than 800 cubic meters, as it is simple to operate and requires less investment. Methanol cracking is better suited for volumes of less than 1500 cubic meters
For hydrogen production equipment with a capacity of 300, using ammonia decomposition is a cost-effective option; it requires less investment, is easy to operate and maintain, and the technology is mature
Why not build a unit with a capacity of 3300 Nm3/h?
This post is great; let’s upvote it. We have here a set of 360 ammonia decomposition hydrogen production equipment, used as a reducing gas and shielding gas in glass manufacturing
