The environmental impact assessment for Huainan Huahua Group’s project to produce 1.7 million tons of methanol and related olefins through coal processing, with an investment of 13.6 billion yuan, has been approved by the Ministry of Environmental Protection. This project is the first to be established in the Huainan coal chemical industry base in Anhui Province. Upon completion in 2011, it will have an annual methanol production capacity of 1.7 million tons. The main products are 490,000 tons of polypropylene per year, 15,000 tons of isobutyl oil, 185,000 tons of gasoline, and 40,000 tons of liquefied petroleum gas. . Note $ # , $ $
““The environmental impact assessment for Huainan Huahua Group’s project to produce 1.7 million tons of methanol and converted olefins has been approved by the Ministry of Environmental Protection” – it refers to the conversion of olefins, right? What does Huaihua Group mainly deal in?

I’m very interested in knowing what technology is being used; it seems that the technology related to MTP has always been kept secret
What a large facility! But the biggest one is Shenhua’s coal-to-olefins plant, which produces 180 tons of methanol per year
Which company’s technology does MTP use?
Another one. Huainan has a lot of coal, and Huaibei also has plenty of coal
I heard that a pilot plant for the MTP fluidized bed process is under construction. When will work begin?
Tsinghua University and China National Chemical Engineering Group Corporation conducted industrial trials of MTP at the Huainan Chemical Plant; currently, when Huaihua Group is building MTP industrial projects, it should adopt the technology developed by Tsinghua University.
It is Tsinghua University’s FMTP (Methanol Fluidized Catalytic Cracking to Propylene) technology, a new approach that uses methanol as a raw material and converts it into propylene products through a fluidized bed reactor. It possesses independent intellectual property rights, with Tsinghua University holding 30% of these rights and the associated revenues, Sinochem Group holding 24%, Tianchen Institute holding 18%, Donghua Institute holding 18%, and Huaihua Group holding 10% of the intellectual property rights and revenues. Previously, two engineering companies built 10,000-ton-class FMTP and catalyst preparation industrial test facilities for Huaihua Group under the EPC model; operation of these facilities was scheduled to begin by the end of 2008, but for some reason, there is still no news of them being put into operation to this day.
I heard that Tianchen Company has established an innovation test base in Tianjin, which includes the sulfurized bed process.
It’s on a similar scale to Shenhua Ningmei’s coal-to-olefins production; is it also MTP? The manufacturing process used by that company for MTP?
Huaihua mainly produces nitric acid, synthetic ammonia, and DMF. It has catalyst plants for coal-to-oil conversion as well as FMTP pilot-scale production facilities; whether Lurgi’s technology or that from Tsinghua University will be used depends on the results of the FMTP tests in mid-year – that’s the likely scenario.
It seems that there isn’t enough catalyst produced for pilot-scale use. So, the pilot plant has never been put into use, right?
In terms of the product, in addition to the reaction process, a separation process is also involved. It’s not clear which company’s technology is being used; there are very few reports on the separation techniques used in MTP. I hope experienced experts can provide some guidance. The reprocessing technology after separation should also be quite popular; I wonder how the pilot test went this time?
It should be \"1.8 million tons per year of methanol\", not \"180 tons of methanol\".
I’m not sure which gasification technology is used for coal conversion – is it water-coal slurry or dry coal powder, and is it domestic technology or foreign technology?
What does the 13 billion yuan in investment refer to? It isn’t clear; if the processing from coal to polyolefins requires only 13 billion, then the cost is much lower than that of Lurgi’s MTP process, whose investment amounts to 192 billion. The biggest difference between the two processes lies in the reactor: Tsinghua University uses a fluidized-bed reactor with a SAPO34 catalyst, along with an olefin recycling system, resulting in an olefin yield that is higher than that of the Lurgi process. The cost of this process should be higher than that of MTO; at the very least, it should be on a similar level. Fluidized bed operation is complex, catalyst wear is significant, and there’s also the regenerator – all of these factors need to be taken into consideration in the cost calculations
How is the output so close to that of Luchi? Isn’t it using Luchi’s manufacturing process?
