Coal chemical equipment and process flows

I’m ignorant and know very little; I have no idea at all. I hope some kind-hearted person can give me some guidance. I would be extremely grateful! ! ! Thank you first
Please go and check out these forums; you’re sure to find the information you’re looking for. However, some resources can only be downloaded if you have certain funds, and you can also get upgrade red packets to enable downloading of those materials: http://bbs.hcbbs.com/forum-147-1.html http://bbs.hcbbs.com/forum-148-1.html http://bbs.hcbbs.com/forum-149-1.html
The general process for coal chemical projects includes coal preprocessing (with the main equipment being used for crushing, screening, and transportation), a gasifier (separate considerations apply for liquefaction), followed by syngas purification (desulfurization, decarburization, conversion, etc.), and finally the production of synthetic products.
There are so many different technologies these days; don’t overcomplicate things for yourself. Since you’re just starting out, decide on which area you want to focus on, study it diligently, and master that one first. Once you’ve done that, it will be easier to pick up the others as well. Coal chemical engineering is highly practical; it’s impossible to truly master it by merely studying materials – it’s essential to relate it to real-world applications.

I’m really grateful after reading everyone’s replies. Thank you so much to all of you! I’m a college graduate this year, and my graduation project focused on the processes in coal chemical engineering. I majored in mechanical engineering, mainly dealing with equipment-related tasks, but I have no knowledge in this area at all. My supervisor didn’t provide any relevant materials, so I had to figure things out on my own. I hope those who know something about equipment can share their knowledge with me – any information related to equipment will be helpful. Since I haven’t decided on my specific topic for the project yet, I’m not sure which types of equipment I should focus on. Thank you again!!!!!
I majored in mechanical engineering; I work on repairing equipment
Why isn’t there any big shrimp to help? It’s sad… I cry :(
You work in design, and the key aspects involve the strength of the equipment as well as the selection of materials for its construction. What you need is information on the mechanical properties of the materials and the choices made regarding the materials used for the equipment. I’m not sure what process you use; most people on the forums are specialists in water-coal slurry and dry powder gasification. Let me help by providing some general information on the materials used in water-coal slurry gasification furnaces. The other aspects aren’t particularly complex, so I won’t go into detail there. In gasification furnaces, due to the very high operating temperatures (1250–1350°C), the interior must be lined with refractory bricks. Since water-coal slurry gasification takes place at temperatures above the melting point of slag, the bricks need to be able to withstand both high temperatures and the erosion caused by the slag. This erosion occurs due to the slag dissolving components of the bricks, as well as through scouring. Since the air flow velocity isn’t very high, this isn’t a critical factor; therefore, Cr90 bricks are commonly used as refractory materials. Most manufacturers choose SA387 as the material for the furnace shell. For the downcomer tubes, INCOLOY825 is used due to its high-temperature resistance. All these materials comply with ASME standards. Another important component of the gasification furnace is the nozzle; both domestic HG188 material and foreign CO50 material can meet the requirements. It should also be noted that, due to the corrosive nature of the ash-water mixture, the quenching chamber of the gasification furnace is lined with 304L material.
I’m extremely grateful for the help from the guy on floor 10; I’ve learned a lot from it! ~ There are so many kind people, haha
Where can I find information on the model numbers of coal chemical processing equipment?
I remember there was a book titled \"Recommendation Manual for Coal Chemical Industry Equipment\"; you can download it and take a look
