The large-scale fertilizer production facilities of Nanhua Group Company
Thread Content
Does anyone know how the large fertilizer production facilities at Nanhua Group Company are performing at the moment, and especially what their costs are? Is crude oil still used as the raw material? Thank you!
Well, I know a bit about this issue; the answer is as follows: (1) Nanhua Group’s large-scale fertilizer project was one of the most unsuccessful investments in China. A total of 2.9 billion yuan was invested in it, and construction took 6 years. After the unit started operating using residue oil, it had to be shut down due to high raw material costs (another reason was that the residue oil delivered via the Yangtze River pipeline often caused blockages), so the project switched to using coal instead. (2) At present, the plant is operating normally after switching from large-scale chemical fertilizers to coal as the fuel source (the conversion was completed by the end of 2006); the urea production section is not in use (as Sinopec gave this section to Ningxia almost for free). Hydrogen is produced solely to supply phosphatic fertilizers, as well as caprolactam for **Hydrogenation and Dongfang DSM, while also meeting part of the hydrogen needs of the company’s own nitric acid production section. (3) From a profit perspective, supplying hydrogen is a good option, but the costs remain relatively high due to geographical factors. I’m not sure if this reply is satisfactory
It’s the Qixia Mountain Fertilizer Factory, right? It introduced French ammonia synthesis equipment; I visited the plant during my university days and found it to be quite good. At that time they were working on developing large-grain urea production facilities. Ah, what a shame!
Bro, you’re wrong; it’s the large-scale fertilizer produced by Nanhua Group, not that of Jinling Petrochemical
I went to Nanhua to take a look; that air separation unit left a deep impression on me, and it represents a milestone in the history of air separation technology.
It’s a pity that what was once the leader in China’s nitrogen fertilizer industry has ended up in this state: the urea plant exploded, the catalyst factory was sold, and the fertilizer plant is also on the verge of collapse.
A few days ago, I attended a conference on water-coal slurry with some people from Nanhua University’s fertilizer department. They are doing quite well with water-coal slurry these days, and I’m really happy for them. Back then, great hopes were placed on that residue oil solution they were using, but it failed.
The brother from the 3rd floor was here in Jinling; we have now switched to coal water slurry
The process of building the new Nanhua plant has been quite full of challenges; another accident occurred in the gasification unit this February. Before the New Year, I had high hopes and signed with Nanhua; but after hearing what others have to say, it seems that Nanhua’s current situation isn’t that satisfactory. Could everyone please share some internal information here? Regarding the latest developments at Nanhua, the raw materials used for ammonia synthesis, which company’s control systems are the best, and which section in the production and operation department is the most efficient... Thank you all in advance!
I have been to Nanhua’s large fertilizer plant; I am also quite familiar with the people there. The current gasification furnace operates at 8.7 MPa, with a diameter of 3.2 meters. Each furnace is capable of producing 300,000 tons of synthetic ammonia per unit time, but it has never reached its designed capacity. The reason for this is that fertilizer production has stopped there, and the facility is now used for hydrogen production. Due to limited demand for hydrogen in the surrounding area, the gasification furnaces operate at a lower capacity. On the first day of work after the Spring Festival, an explosion occurred in one of the furnaces, resulting in one death and six injuries. Production was not resumed until mid-March. Nanhua follows a typical state-owned enterprise management structure; despite having many skilled employees, problems keep arising in terms of production as far as I know
Nanhua has been trying to seize opportunities, but it never seems to succeed. From joining Sinopec to the merger of the various Nanhua entities, the company has always claimed to be seeking development by taking advantage of opportunities – yet things only got worse. An explosion on the first day of work after the Spring Festival was inevitable; if it didn’t happen then, it would happen later. Explosions have occurred many times at Nanhua, and it has become something normal there.
