Everyone, please take a look and see if the inspection itinerary I’ve arranged is satisfactory

Both Huisheng and Yankuang Yulin projects were designed by Tianchen Institute; it’s better to go straight to Tianchen then! Hehe! I’m the design representative for the pipeline systems at Huisheng, and I’ve witnessed the entire process, from installation to the production of methanol/

An innovative technology for producing methanol via coal gasification along with ammonia and urea has been developed. Producing methanol through pressurized gasification using pure oxygen, and co-producing ammonia and urea from the methanol off-gases, represents one of the most effective ways to make comprehensive use of coal by converting it into clean energy sources and fertilizer products. It is a new ammonia-methanol production process that features energy savings, reduced consumption, recycling, and environmental protection. In this process, the CO+H2 syngas used for ammonia and methanol production is derived from the conversion of coal or hydrocarbons. Due to the gasification temperature of 1400–1700°C, the coal utilization rate can reach 99%, with only 0.3% CH4 in the gas, while the yield of CO + H exceeds 90%. Per ton of ammonia, 282 m3 of off-gas is generated during the synthesis process, which is then converted into synthetic ammonia and urea. At present, many places such as Sichuan, Shanxi, Inner Mongolia, Heilongjiang, and Ningxia are building such devices, and this technology is showing strong development momentum.

Is the guy from Tianchen? Could you recommend some experts who can give us advice, or introduce someone in charge to save us the trouble? This post was last edited by BG3GDA on 2009-2-2 21:24.]

Methanol is losing money right now. Pay again?

It is recommended to first visit the manufacturer, listen to the opinions of actual users, and then discuss things with a design firm – this will be beneficial

Hehe~~ This is a wonderful assignment. There are representative enterprises in China involved in coal-to-methanol projects; it is beneficial to listen to their opinions.

It would be better to reverse the order of the itinerary and then repeat it again.:)

Let me share my personal opinion: 1. Fixed-bed gasification is definitely not an option； 2. In water-coal slurry gasification, processes such as Texaco and four-nozzle systems are widely used in China at present, and the related technologies are relatively mature; the localization of key equipment for water-coal slurry gasification has also been successful ； 3. In powder coal gasification, SHELL is still the most widely used technology in China; other options have not yet reached a scale of commercial use. To date, this technology remains somewhat less developed compared to coal slurry gasification. However, powder coal gasification has attracted attention from various sectors in recent years, and many new processes have been developed. It is claimed that this is the direction in which the coal chemical industry should develop, but it will take some time to prove this ； 4. Mature processes can be used right away, but there is little possibility for further optimization ； By using new manufacturing processes, especially those developed domestically, significant savings can be achieved in terms of initial investment. However, such processes must withstand the various challenges that arise after they are put into use; success leads to fame, while failure results in disaster. That’s right: high risk corresponds to high returns, while low risk corresponds to low returns; this is the same principle behind the saying \"The stock market involves risks, so one must be cautious when entering it.\" When those experts predict which manufacturing processes are the best or have the most potential for development, they are relying on past examples; it’s almost like gambling – it’s based on probability statistics. It’s possible that we might encounter that 000000000.1% chance that we consider impossible, but it’s hard to say for sure.

Yankuang Luhua possesses two mature technologies: GSD and four-nozzle. The products include methanol and synthetic ammonia.

Thank you all for your attention. The furnace type has been basically chosen as Texaco; three nearby facilities also use Texaco, and it is suitable for the type of coal used, as well as in terms of maintenance and after-sales support. We welcome further suggestions from you – which plants, those producing 600,000 tons of methanol or those using Texaco technology, are more relevant as a reference?

It is recommended that the original poster save time and effort by first carrying out the basic work properly within the company (such as the current status and development trends of methanol production, process technologies, product options, coal quality, construction timelines, selection of key equipment, etc.), and only then go to representative manufacturers (formaldehyde plants using different processes, those with stable or unstable production) to conduct a thorough study (rather than just a superficial look), in order to learn from their experiences and insights regarding engineering design and process routes. Before going to the manufacturer, prepare an outline of the topics to discuss and send it to them in advance; this will allow for a targeted discussion, and I believe you will gain a lot from it. As for going to the design institute to \"seek advice on the process plan and discuss the design contract,\" I suggest having them come to you. There are several engineering companies capable of carrying out methanol design; each specializes in the engineering design of different process technologies, and each has its own strengths. Ask them to come and give a presentation; at least that way more people in the company can learn about it and provide their opinions. “When it comes to discussing design contracts, they are usually standard forms, so there’s not much to discuss. As for consulting the XX Methanol Association about the current status and development trends of methanol production, I think it would be better to cover part of the costs so that the association can send one or two experts to the company to give a presentation; this way, more people can become aware of the situation. In fact, there are an increasing number of “associations” these days, with a mixed quality of members – you can choose to pay attention to them or not.

For coal-to-methanol projects, first: what raw materials to choose and which technologies are suitable. What is methanol used for? Second, the situation of manufacturers using similar technologies in China. Third, the origin of the technology and engineering design. Fourth, it is not necessary to consult the Beijing Methanol Association regarding the current status and development trends of methanol production. No one can see the direction of methanol right now. Fifth, when dealing with methanol now, one must be fully prepared to incur losses

First, one needs to go to the design institute to discuss process technologies, investment costs, etc., based on factors such as the quality of the coal. Then, they go to the enterprise to examine equipment control systems, and after that return to the design institute for further discussion

The design institute does not explore process technologies based on factors such as the quality of its coal; first, it selects a company specializing in coal gasification technology, purchases that technology from them, and then uses it in its designs.

Rengeyong, you are right – the design institute does not possess its own gasification technology. However, in a situation like the one you described, it is not appropriate for the client to seek out a gasification technology provider on their own, because 1) every gasification company will present itself in the best possible light, and 2) the client is likely not sure which technology would be most suitable for them. Usually, it is the design institute that handles these discussions, including those related to gasification as well as the various subsequent processing technologies. These are immature opinions for reference only

The original post was published by Ling Lianqun on 2009-2-2 at 21:11. Both Huiseng and Yankuang Yulin had their designs done by Tianchen Institute; it would be better to go straight to Tianchen! Hehe! I’m the design representative for the pipeline systems at Huiseng, and I’ve witnessed the entire process, from installation to the production of methanol as a finished product. Are you from Tianchen? Could you recommend some experts who can give us advice, or introduce some people in charge so we don’t have to go through extra trouble?

Rater: Wise Ming Wealth +3 No wonder there are so many design changes. Date: 2009-2-3 09:32. May I ask, Wise Ming, what do you mean by giving me extra points? Is there a relationship between having more design changes and the quality of the designs? Besides, which design firm ever has no changes at all in their designs? Given your level of expertise, I really doubt how you became a moderator! If you have any opinions, we can discuss them over QQ!! I’m very angry, and the consequences could be serious!!

We come from the coal industry, so we don’t know much about the chemical sector, and we don’t have any friends in that industry. We are very grateful to see everyone responding so enthusiastically. Right now, not even the chief engineer has arrived yet. **We’re being pressured by the boss, who in turn is pressuring us – it’s like forcing ducks into a cage. I hope friends from all over can offer more suggestions.

First, go to the association and the design institute; also consider asking them to push things forward with the manufacturers, otherwise the manufacturers won’t agree to meet either, right?
