Successful industrial application of ethanol dehydration to produce ethylene November 26, 2008, 11:43:44 Source: Sinopec News Network, Shen Yan. Developed independently by the Shanghai Research Institute, this technology has been successfully implemented in 5 industrial units. According to Sinopec News Network, recently, Shanxi Sanwei Group Co., Ltd. utilized the ethanol dehydration to produce ethylene technology developed by the Shanghai Research Institute of Sinopec to establish a functional production process and obtain high-quality ethylene product. To date, the ethanol dehydration to ethylene technology independently developed by the Shanghai Institute has been successfully operated in 5 industrial plants. Bioethanol is a renewable resource, and the bio-based ethylene produced from it serves as an important supplement or alternative to petroleum-based ethylene. The advantages of bioethylene are particularly evident in areas where the demand for ethylene is only small and transportation is difficult, as well as in regions lacking petroleum resources. Currently, oil resources are becoming increasingly depleted, and oil prices are volatile, posing various challenges to the sustainable development of China’s ethylene industry. Under the situation of domestic energy shortages, developing the technology for producing ethylene from bioethanol can effectively leverage the advantages of domestic biomass resources and alleviate the oil crisis, holding significant strategic importance. At present, the ethanol dehydration to ethylene technology developed by the Shanghai Institute has been successfully applied industrially in various factories, including the Sichuan Vinylon Factory, the Guangxi Vinylon Factory, and the Shanxi Vinylon Factory. The downstream products resulting from this technology are mainly EVA resin or VAE emulsion. In fact, the ethanol dehydration to ethylene plant can supply ethylene as a raw material for EO/EG plants, styrene plants, and polyethylene plants, offering very broad application prospects. The successful commissioning of the ethanol dehydration to ethylene plant at 3D Group once again demonstrates that the technology developed by Shanghai Institute for ethanol dehydration to ethylene is highly mature. The successful operation of the ethanol dehydration plant for producing ethylene provides a new pathway for further expanding the application areas of new energy chemicals. It also lays a solid foundation for Sinopec to enter the future new energy market, making new contributions to the development of this sector.

Some use ethanol to produce ethylene, while others use ethylene to produce ethanol. . .
The price of ethylene seems to be higher than that of ethanol; ethanol costs around 5,000 per unit, so what about ethylene? Those who know it, please fill in the details; I’m not sure what the advantages of this technology are This post was last edited by qinweijun on 2008-11-28 13:03.]
I remember that ethanol seems to be cheaper than methanol! Last edited by qinweijun on 2008-11-27 13:30]
A few weeks ago I was just designing equipment for ethanol production – it was exhausting……
Anhui Fengyuan Biochemical has been in production for many years, right?
It opens up another path for biotechnology, as it can be used as an energy reserve. However, the cost issue does not seem to have been mentioned. Based on the usual practice in domestic reports, if the cost were low, it would definitely be given priority in coverage. Since the cost is not mentioned in this report, it implies that the cost is either similar to existing levels or not economical enough; it’s merely a matter of industrial application at this point.
At best, it’s just a technical reserve – it won’t generate any money!
There is probably no profit margin left in this area now; when oil prices were around $150, the price of ethylene was over $7,000. The cost of food ethanol is around 4,000 yuan. The current price of pure ethylene is 430–440 US dollars per ton, CFR Southeast Asia; converted to RMB, that’s around 7 yuan per ton. You can do the calculation yourself.
