Does anyone have any information on the processes used for producing acrylonitrile? What is the mainstream process currently in use? Maximum scale per device? Which manufacturer has the best technology? Thank you all! ! !
I know that Lianyungang Sierbang Petrochemical has this facility; it was a project managed by Huisheng, but later it was handed over to Sinopec Shanghai Design Institute.
Some time ago, when I was looking for propylene cyanohydrin, I also inquired about acrylonitrile. I remember that the manufacturer currently in operation is Jihua (the production volume can be found on Baidu; I can’t recall it exactly). Shanghai Sinopec has waste material that is supplied to Lucaite next door. Shandong Krull Chemicals has a production capacity of 260,000 tons for acrylonitrile; I can’t remember anything else. From what I researched at that time, there aren’t many acrylonitrile production facilities in China. Due to strict environmental regulations, many of these facilities are only operating at partial capacity. I welcome any corrections from others
Thank you all. I am interested in setting up an acrylonitrile production facility, but I haven’t made a decision yet; I need to investigate the situation first.

China’s large-scale acrylonitrile plants all import technology from the American company BP. Currently, 95% of the world’s acrylonitrile production relies on the Ohio acrylonitrile oxidation process. After more than 50 years of development, this process technology has become highly mature, having replaced the previous process that used acetylene as a raw material. Since its introduction, no significant improvements have been made to this process; efforts have mainly focused on the development of new catalysts and new types of fluidized-bed reactors. At the same time, process upgrades aimed at reducing energy consumption and environmental impact have been carried out to improve the efficiency of the plants. Recent advances in catalyst technology have enabled an increase in the acrylonitrile yield by 20%, bringing it above 75%.
