Shandong Runxing produces adiponitrile – is it technology developed in-house?

Without understanding the situation, solve it the same way……

There’s no need to understand anymore; everything has been destroyed, and the factory was built for nothing

Uh. . . . . . . . . . . . . . . . . . . . . . . .

I heard it was developed by them themselves; you can’t find out such things here.

I heard before that anyone who could turn adipic acid into hexacyanide would become very rich

The hexanenitrile and HDI industrial chains independently developed by Shandong Runxing Chemical Technology Co., Ltd. have obtained multiple **patents, filling a gap in China’s industry and reaching international advanced levels. Developing an HDI and hexanenitrile industry based on non-phosgene technologies with independent intellectual property rights is essential for fundamentally changing the structure of China’s polyurethane industry and its products, and this has become an urgent priority for that industry. The company’s industrialization project, which has an annual production capacity of 100,000 tons of HDI and 300,000 tons of adiponitrile, has been listed as one of the first batch of provincial strategic emerging industry projects in Shandong Province. In December 2011, the Science and Technology Department of Shandong Province organized an evaluation of Runxing’s scientific and technological achievements in the areas of “Electrochemical Synthesis of Adiponitrile Technology and Industrialization” and “Non-phosgene-based Hexamethylenediisocyanate (HDI) Technology and Industrialization”. The evaluation committee was composed of five academicians from the Chinese Academy of Engineering—Li Junxian, Wu Weizu, Li Zhengming, Shu Xingtian, and Sun Baoguo—as well as four professors: Wang Daquan, Ma Chunan, Wu Chunzhi, and An Zhongwei. The conclusion of the evaluation was that the adiponitrile project “filled the gap in domestic production of adiponitrile, with its overall technology reaching international advanced levels” (Lu Ke Cheng Jian Zi No. 1312) ； The HDI project’s overall technology has reached an internationally advanced level”

If it is developed independently, it’s normal for it to explode; currently, domestic research institutions are still weak in terms of safety. Moreover, relying on company staff to ensure production safety without supporting safety systems such as SIS poses a significant risk.

All these acceptance criteria focus on the manufacturing process and the product itself; in other words, they only consider whether qualified products can be produced, without taking into account factors such as the level of automation or safety.

You know quite a lot about it. . . Say a bit more, and it’s better to be specific. . . . .

Well, it seems the product line is functioning properly; otherwise it wouldn’t have been able to sustain itself for such a long time. Security failures are complex, and they are also related to companies being overly conservative in their technology approaches and unwilling to allow security experts to conduct inspections
