Ammonia vaporization unit
Thread Content
There are two options for the tray types in ammonia vaporization towers: one is the vertical sieve tray produced by Hebei Zhengyuan, and the other is the CJRS jet-type tray developed by Tianjin Chuangju. I’m not sure which one is better; those who have used these two types of trays could share their experiences! Thank you
How is it that no one has replied to such a great post? It’s a shame I don’t understand; I was just trying to find out
Who said there are only two options? I think the three-dimensional mass transfer tray CTST developed by Hebei University of Technology is better; if you don’t believe it, you can go to www.ctst.com.cn to take a look
Tianjin’s innovations also include vertical drying boards, and we use them very well
Tianjin Chuangju also has vertical drying plates; we use them very effectively, and they are employed in ammonia vaporization towers as well.
3#: ctst may have a wider range of applicability, but they didn’t recommend this option to us. Our ammonia treatment capacity is only 5 t/h. 4#: Vertical sieve plates are relatively inexpensive; we are considering them. The key question is whether they can meet the requirements. Could you tell us what levels the ammonia concentration in the gas phase at the top of the tower and the ammonia content in the waste liquid at the bottom of the tower can reach according to your process?
Hehe, the original poster doesn’t know this – the innovative technology originated from our area. Only simple changes were made to its structure; note that it’s a change, not an improvement. Our hooded cover is a patented product that has won the First Prize for Scientific and Technological Progress in Hebei Province, as well as the First Prize for Scientific and Technological Progress in Tianjin City, plus the Award for Outstanding Contributions to Science and Technology in Hebei Province. It’s more advanced than theirs, so he certainly won’t recommend his competitors to you :)
Winning an award does not necessarily prove good performance! When it comes to ammonia vaporization, the key factors are performance, the manufacturer, track record, and cost-effectiveness. As far as I know, there are many manufacturers that use Hebei Zhengyuan’s vertical sieve plates; here are a few examples: 1. Shijiazhuang Baipo Zhengyuan Fertilizer Co., Ltd.; 2. Hebei Dongguang Chemical Co., Ltd.; 3. Shanxi Lanhua Kechuang Co., Ltd.’s Fertilizer Branch; 4. Fengcheng City Fertilizer Factory in Liaoning; 5. Shijiazhuang Zhengyuan Fertilizer Co., Ltd.; 6. Lanhua Kechuang No.1 Fertilizer Factory; 7. Puyang County Fertilizer Factory; 8. Jiangsu Heyou Group; 9. Hubei Dangyang Huahua Chemical Co., Ltd.; 10. Jiangsu Runfeng Biochemical Co., Ltd.; 11. Jiangsu Suqian Chemical Co., Ltd. . . . . . Many, I won’t list them all.
For ammonia evaporation, a plate tower is not necessarily required; packing can also be used. We use packing, with the concentration at the bottom of the tower being below 0.1%.
It seems the discussion among everyone is quite intense!
There is another issue: the process provided to us by Hebei Zhengyuan involves preheating before both towers and cooling at the top of both towers. With tower heights of over 16 meters, it is necessary to use a framework; otherwise, the coolant from the top of the towers would not be able to flow back into the ammonia vaporization tower. We, on the other hand, do not want to use a framework for the ammonia vaporization process, as this would inevitably lead to increased costs.
Bro, the CJST tray invented in Tianjin was also designed by Hebei University of Technology, and it has won **multiple awards as well. I wanted to go to Hunan and Shaanxi to see how it’s being used, just like my twin brother did; however, I wasn’t able to make that trip. I’m not sure what advantages your trays have exactly.
Companies will make the best choices for themselves. Zhengyuan’s three own subsidiaries all use the vertical sieve plates produced by Hebei Zhengyuan, and as far as I know, they also use their own vertical sieve plates in several major projects they are working on currently. If these sieve plates were not as good as the CJRS jet-type ones developed by Tianjin Chuangju, they wouldn’t continue to use them – after all, no one wants to unnecessarily increase their costs
Taihua uses CTST trays from Hebei University of Technology, with an ammonia content in the tower bottom less than 0.003%
I have a gentle question: how complex is ammonia distillation? Let’s talk about the composition first. If it’s good, that’s fine; don’t do advertising here
