Collected by large ammonia synthesis manufacturers using the Kellogg process hydrocarbon steam reforming method
Thread Content
There are mainly three types of hydrocarbon steam reforming processes commonly used in modern large-scale ammonia synthesis plants: the Calog process from the United States, the ICI process from the United Kingdom, and the Topsoe process from Denmark. The large-scale ammonia synthesis plants introduced in our country can be classified into the following three types based on the design company: ① K-type plants: Kellogg (American Kellogg Company), using the American Kellogg process; ② T-type plants: TEC (Japanese Toyoe Engineering Company), also using the American Kellogg process; ③ H-type plants: Heurtey (French Heurtey Company), using the Danish Topsoe process. Please help gather information on domestic ammonia synthesis manufacturers that use the Kellogg process, as well as details about these manufacturers and the current operating status of their facilities.

The two sets of 300,000-ton Kellogg ammonia synthesis plants are currently operating normally at 85% capacity
The original poster raised a very good topic; I still haven’t figured out what kind of process we actually use. Is there any relevant material available to help me learn*? OP.
As far as I know, apart from Ningxia Petrochemical’s second fertilizer plant, there are also two units owned by Ordos United Chemicals, as mentioned earlier. I am quite familiar with this company as well, since their staff used to train here. There are also the units from the fertilizer plant of Daqing Petrochemical Company, those from Cangzhou Dahuahua, the second set from Lutianhua, as well as those from Chitianhua and Yuntianhua. Although most large-scale ammonia synthesis plants these days use natural gas as raw material, (most small and medium-sized ammonia synthesis plants use coal as raw material; among large-scale plants, Shanxi Jinhua seems to be the one that relies heavily on coal.) ) However, there aren’t many classic Kellogg processes; many of them originally used residue as a raw material. But for a period of time, the price of residue was very high, which resulted in low profitability for many manufacturers. As a result, most of these processes were modified to use natural gas, in what is known as the “oil-to-gas conversion”. The current trend is that, since natural gas is a clean energy source with limited reserves, there are restrictions on the use of natural gas in chemical manufacturing. On the other hand, China has substantial coal reserves, and coal gasification technology has become quite advanced. As a result, the coal chemical industry in China is thriving, with many manufacturers conducting studies to evaluate the feasibility of switching from using gas to coal.

We are a K-type factory, Kellogg (the American company Kellogg), following the Kellogg process from the United States. Now it has also been changed to gas instead of coal. Natural gas is extremely scarce right now. However, our factory operated continuously for 249 days in 2007.
Our plant also uses the Kellogg process from the United States, but it produces only 200,000 tons of synthetic ammonia per year; in 2007 it operated continuously for 334 days

Apart from these, our unit originally also had one, but it has been replaced with a coal-fired unit with a capacity of 26W.
We are a K-type factory, Kellogg (the American company Kellogg), following the Kellogg process from the United States. An annual production of 500,000 tons of ammonia. In an environment with abundant coal resources, projects to replace gas with coal are also being undertaken now. Coal chemical industry will become the mainstream of the chemical industry in the future.
Which one of the three LZ types does the Brown process belong to?????
Mine uses natural gas as a raw material; I checked some books and it seems that our process is also from Kellogg. But I’m still not sure if it is or not. Mainly, no professional books were found for comparison. Many internal documents cannot be obtained. It’s like I’ve been working in an ammonia synthesis plant for 8 years now, and only recently have I come to understand that there are several different processes involved in ammonia synthesis. It’s hard. It seems I’m really far behind. Lack of information. I feel like I’ve become a frog in a well.
