Dear experts: I have very little knowledge about ethylene glycol. Our company wants to undertake this project, and I would like to ask for information regarding the production technology of ethylene glycol.
Currently, ethylene glycol is produced by the hydration of ethylene oxide, but recent breakthroughs have been made in the technology for producing ethylene glycol from syngas; for more details, please check the relevant posts on this forum!
If you want to discuss something, it’s better to specify the topic clearly; being too vague wastes everyone’s time. I’m not sure whether I should get involved
The technology for directly producing ethylene glycol from syngas is a technology under investigation. The Fujian Institute of Material Structure conducted pilot tests. The Huayang Chemical Plant in Danyang, Jiangsu, has carried out pilot tests with a capacity of 500 tons per year; it is currently working on the design for a demonstration plant with a capacity of 10,000 tons. There is still a long way to go before this technology can be industrialized; it must overcome challenges related to both processes and economics.
Expert-level explanation. I have also been following this technology for a long time, and based on the current situation, it will still take some time before it can be truly industrialized. The technical route for producing ethylene glycol directly from syngas involves several major technical challenges that need to be addressed: 1. Catalyst selection and preparation. Modern chemical industry requires efficient and long-lasting catalysts, which are of utmost importance ； 2. The engineering of the process route, including PDP simulation and development, selection and optimization of automatic control schemes, and recycling of materials ； 3. The selection of equipment materials and the determination of the equipment structure, including reactors, purification equipment, heat exchange equipment, etc. From the laboratory to industrialization, one must take things step by step; there are no shortcuts. Therefore, for this technology, one must be patient and not rush things. Under no circumstances should one spout nonsense just to go along with the calls of* members; otherwise, it will be the people doing the work who suffer! !
