Xiaoji asked me about shell coal gasification technology.
Thread Content
My younger brother is a reporter from China Chemical News. After learning that Shell’s coal gasification technology signed the 16th technology transfer contract, he planned to do a special topic on this technology. I was very excited after discovering this forum and sincerely hope to exchange knowledge with people in the industry.* , I hope you can share your opinions on Shell’s coal gasification technology. Thank you so much. :handshake phone: 010-82032064 email: blueice094@hotmail.com
Today's reporters usually ask others to write it, sign it with their own names, and then take several articles and publish them together. You don’t have to study so hard * :lol, I don’t think it’s realistic to understand it thoroughly. Many big experts may not know it clearly because they haven’t been to the front lines of driving. If you really want to write something of your own, please go to 5 factories that have started to do research. If they are willing to tell you the truth, you will gain a lot.
Let’s start with a cold surprise. It is said that none of the factories using Shell coal gasification technology are currently running stably... China is regarded by Shell as an experimental field for gasification technology... Haha, but I guess if you want to report this, it will definitely not pass the review.
Haha, it seems that everyone knows a lot about our industry. I don’t want to exclude foreign technology with colored glasses, but I just want to objectively understand the views of industry insiders from different positions. Maybe there were other more important purposes when this technology was introduced, but as a technology that costs a lot of money to introduce, I think it will also have its merits after expert argumentation and inspection, at least there are things we need to learn. * place. The industrial application of technology will definitely have many ups and downs, so I hope you can give me some advice regardless of praise or criticism. There are many experts in the forum who have introduced this technology. You are all exposed to this technology and I really want to learn from you. * , learn in the process of finding problems * , I think after seeing the newspaper, more people will come to exchange research together. Of course, I will definitely investigate it. I also know a little bit about the basic operation situation, and I hope to hear your opinions.
What aspects of the situation the poster needs to know should be clearly stated, such as: 1. The progress of the project； 2. The production status of projects that have been put into production and the main problems encountered ； 3. The situation of other major competing gasification processes, etc. ……In this way, the questions are clear and purposeful so that everyone can answer them.
The 6th floor has a very detailed explanation of SHELL gasification, but one thing I have doubts about is its load adjustment. It usually has four nozzles. When reducing the load, if any nozzles are not used, they must be protected. After the protective gas enters, the gas composition should drop quickly. I think everyone should pay attention to this. In addition, as far as SHELL gasification is concerned with gasifiers, coal consumption and oxygen consumption are indeed lower than wet gasification. However, as a manufacturer, it is necessary to comprehensively evaluate the entire system and conduct a comprehensive analysis of investment and energy consumption. At present, domestic dry gasification is mainly designed by Wuhuan Engineering Company. After communicating with Wuhuan personnel, they also believe that if the coal type is suitable for wet gasification, wet gasification should be selected. Only when the coal type cannot be wet gasified, dry gasification should be selected.
Several of the questions you listed are what I really want to know. I also want to know more: 1. What were the thoughts (reasons, goals) when my country introduced this technology, as well as some background at that time, and what will be the future development? ； (Maybe this is a matter for the leaders. If you have any news, can you tell me) 2. The five projects that have been put into production may have encountered different problems and consumed a lot of resources and funds. Do you think it can be successful, or how much will the cost of success be? ； 3. What impact do you think this technology will have on the development of our own coal gasification technology? ； There are also aspects that I haven't thought of, and everyone is welcome to add. Thank you for your support, thank you. This post was last edited by blueice094 on 2007-12-21 13:37 ]
