Currently, in China, there are two-tank and three-tank condensation technologies for butadiene production units; the two-tank condensation method is represented by Daqing Petrochemical, with Sichuan Petrochemical, Dushanzi Petrochemical, Jutai Energy, and others also using this approach. Sanfu Condensation is represented by Baling Petrochemical; in addition to this, other companies using Sanfu Condensation include Yanshan Petrochemical and Shandong Yuhuang. As for Qilu Petrochemical, Takahashi Petrochemical, Maoming Petrochemical, Jinzhou Petrochemical, Xinjiang Lande, Fuxiang Chemical, Zhejiang Transfar, Shandong Qixiang, Shandong Wanda Chemical, Shandong Huamao New Materials, Liaoning Shengyou, Yantai Haopu, Nanjing Jinpu, and Shouguang Fenghui – is the synthesis of styrene-butadiene rubber in these companies carried out through two-stage condensation or three-stage condensation? If any friends know, they can add information here to see whether double-reactor or triple-reactor systems are more commonly used for butadiene polymerization in China We welcome all friends to actively participate in the survey!
After some investigation, Qilu Petrochemical and Qixiang use three-reactor condensation; the situation of other companies is still under investigation. We hope that those in the forum who work in the butadiene industry can provide information on these other companies!
It’s definitely the three-kettle type that is used more often; it’s the mainstream nowadays
Takahashi has two kama, and Kaoying has three kama. In short, the newly introduced units all have three reactors, while the older units have two reactors; a considerable number of them have also been upgraded from two reactors to three. The modifications to the three reactors that involved mastering core technologies were relatively successful, whereas those that were based on copying or imitation were not successful at all, as was the case with a certain private enterprise.
Sanfu is the trend. However, the three-vessel process does have its merits. In China, there are many fake three-vessel processes that use three vessels, but such systems result in high consumption levels and suffer from serious operational problems.
Sanfu has a clear advantage; technology is the key.
Yes. Energy savings and consumption reduction in synthetic rubber production facilities – feel free to contact us if you need assistance! :)
Maoming has three furnaces, but it is not the optimal configuration for three-furnace condensation
Currently, for consolidation purposes, three reactors are mostly used, and they constitute the main force. No matter what products are produced, Sanfu can improve in many areas.
According to the investigation, Sanfu currently has a clear advantage, with better control over temperature and residence time, :)
