Discussion on the entire process route for constructing a new coal-based urea plant
Thread Content
To our friends still in Haichuan: Our company plans to build a new urea production facility, while also producing alcohol-based products. Following the approach of low carbon emissions and diversification in coal chemical processing, we would like to ask you: Is it better to use multiple smaller air separation units, or one large-scale unit? ), gasification (BGL, coal dust waste boilers, water-coal waste boilers, other gasification technologies), shift reaction, methanol production, synthesis 1 (ammonia – the current mainstream technology; whether the catalyst is efficient) / synthesis 2 (alcohols), urea (which process? ), the advantages of choosing PMC Company for project management, whether digital delivery is implemented in project construction and what benefits this brings to subsequent production, the compatibility between domestic/international intelligent control IPC systems and DCS, and the degree of automation in the plant’s powder handling systems (for coal, urea, etc.) The sulfur recovery section ends with what type of product. I would greatly appreciate hearing the opinions of all fellow sailors!
Many of the issues here cannot be addressed by netizens; they depend on the scale, amount of investment, and company practices*. For example, in the case of air separation, it depends on the scale of air separation required; the gasifier is also related to the quality of coal used, as well as the processing capacity. I’ve worked on many projects involving water-coal slurry boilers. Whether one has experience in project management depends on the specific circumstances of one’s own organization. Outsiders cannot provide answers to these questions. One more thing to say: digitalization is nothing but a complete scam. The final form of the product also depends on your target market, not on what internet users say
:The knowledge required for lol is really quite broad
The issue you mentioned is highly technical in terms of design, and few people are able to answer it.
Thank you all for your replies; we are continuing our research!
This isn’t something that can be explained in just a few words. It’s recommended to conduct more market research; is there still a requirement to use urea these days?
A water-cooled coal boiler can be used, or it’s not necessary to use one at all; it depends on the pressure level. The most reliable option seems to be the system used by Hualu Hengsheng – it would be worth going and taking a look at it
The key factors are scale and coal quality; for air separation, low-carbon processes, and sulfur recovery, existing mature technologies can be used. Sulfur recovery to produce sulfur is also an option; prices are quite high these days. Making sulfuric acid is also possible.
