Koutai Energy’s 300,000-ton/year dimethyl ether pilot plant in Zhangjiagang
Thread Content
The 300,000-ton/year dimethyl ether project of Jutai Energy in Zhangjiagang has completed successful commissioning.
Could you please provide information on the amount of investment, the land area, and the staffing situation?
Warm congratulations! Jiutai Energy is very strong! :Lol! There are Phase 1, Phase 2, and Phase 3 – the ambition to become the leader in the dimethyl ether industry! It is very satisfying to be able to cooperate on the refractory lining project for the gasifier in Jutai’s Inner Mongolia project. Let me advertise this: all 4 sets of refractory materials for gasifier linings were manufactured by our company. :Loveliness: The company’s technical staff also gave us some advice; our company doesn’t do enough in terms of marketing. The quality of our products is widely recognized by those manufacturers that use them, but the lack of effective marketing means that many new industries are not very familiar with our company. This is a shortcoming in our work. This post was last edited by dddjie on 2008-1-25 22:05]
Free process – have you never heard of Jiu Tai’s liquid-phase method? It’s leading in China
I was wondering if the owner could provide information on the raw material supply chain and the investment details for this project. It is said that Jiutai’s dimethyl ether product meets only a purity level of around 96%, which is far lower than the 99.9% achieved by Lutianhua Group. It’s not clear whether this is true or not
For the Jiutai dimethyl ether project, coal gasification is carried out using water-coal slurry gasification, and specifically the four-nozzle opposed water-coal slurry gasifier from the Coal Chemical Engineering **Center. The contract was signed in January 2007; the amount of the contract cannot be disclosed, haha. The dimethyl ether technology uses a two-step catalyst for liquid acid production: first, methanol is prepared, and then dimethyl ether is synthesized from methanol in the presence of concentrated sulfuric acid, concentrated phosphoric acid, and a small amount of sodium hydrosulfide as a catalyst.

OP: Don’t rush. Don’t use abusive words; it’s not good. I am also a member of Jiutai, and this is detrimental to our company’s image. Moreover, different processes have their own characteristics and all come with certain limitations; for example, ours also have its shortcomings ； Everyone’s experiences are different; no one is a saint, and everyone makes mistakes from time to time. Facts speak louder than words; to convince others, present the data: what is the actual operational capacity? How much to invest? What are the various consumption indicators? If New Energy, Lutianhua, and Tianyi all have inferior technology to ours, wouldn’t it be clear if we compare them?
There is currently little information available on Jiutai’s liquid-phase method. Your view is very apt; different processes have their own characteristics, and each method has certain limitations, so a technical comparison should be made. Better than investment, consumption quotas and energy consumption, the quality of environmental protection, and stable and reliable operational capacity. Comparison can be convincing and can also drive technological progress.
Poster: During the Spring Festival, I heard from a colleague at Jiu Tai that the 300,000-ton dimethyl ether project in Zhangjiagang was only in the trial operation phase before the festival and had not yet entered the stage of feeding materials; I wonder if trial operations with material feeding have started now Has the capability reached the designed level? How is the consumption? Let everyone share it.
Everyone is here to learn*, so if you have an opinion, feel free to express it; there’s no need to overreact. This post was last edited by cxwl007 on 2008-2-27 13:32.]
Zhangjiagang should produce dimethyl ether directly from methanol, right? I don’t know how to transport methanol from Inner Mongolia By rail or by road, and should water transport be used as well? How should transportation costs be taken into account?
Which refractory materials company are you from? Didn’t the promotion mention the organization’s name either?
Methanol is purchased from outside; it is not transported from Inner Mongolia, and it can be imported
It seems that the original poster knows quite a lot about Jiu Tai Energy’s dimethyl ether project. Could you provide more details? Such as investment status, process route, commissioning status, etc.
Back to the 15th floor. Thank you for the reminder. I work at Sinosteel Refractory Materials Co., Ltd., which was formerly known as Luonai Factory – a state-owned enterprise established in 1958 and the leader in the domestic refractory materials industry.
Everyone wants to know about the investment status, process routes, commissioning progress, etc. Thank you.
What kind of refractory materials are used in dimethyl ether gasifiers? Lining material or bricks? I’ve never used a furnace like this; I’m very interested in learning more about it. Please answer
