On September 12, Xingchuan New Materials announced via its official WeChat account that its world-first 10,000-tonne-per-year industrial plant for hyperbranched polyolefin elastomer (H-POE) had achieved a successful one-shot start-up, with the first batch of on-specification products rolling off the line.…
قد يحتوي المنتج الخارج من مفاعل البلمرة بالمحلول على مذيب من نوع 80%–90%. ويجب أن تهدف المعالجة اللاحقة إلى إزالة هذا المذيب، واستعادة المونومرات التي لم تتفاعل عند الضرورة، وتحويل البوليمر المركز إلى شكل مستقر وقابل للبيع، مثل الحبيبات. وتزداد صعوبة هذه العملية كلما…
مقدمة: عندما يبحث الناس عن “عملية إنتاج الأنيلينو أسيتونيتريل” أو “كيف يتم إنتاج الأنيلينو أسيتونيتريل”، فإنهم عادةً ما يركزون على معدل التحويل في التفاعل ونقاء المنتج. غير أن المصنع الصناعي يجب أن يجيب أيضًا على عدة أسئلة أخرى: هل يمكن الحفاظ على استقرار المحلول الوسيط «جليكولونيتريل»؟…
How Inclined Plates Improve Mixing, Heat Transfer, and Deposit Control Inclined-plate static mixing elements redirect fluid inside a pipe to strengthen mixing and reorganize the internal flow field. Unlike densely crossed or highly obstructive static mixers, they use relatively open,…
Reactive dividing-wall distillation combines reactive distillation with dividing-wall distillation in a single unit. The core equipment is known as a reactive dividing-wall column, or RDWC. Reactive distillation carries out a chemical reaction and component separation inside the same column. Dividing-wall…
W4 Column Design Series: Final Engineering Case Study This case study connects the principal elements of column design covered in the previous six articles: valve-tray fundamentals, design standards, hydraulic calculations, high-efficiency trays, operating optimization, and simulation tools. The project involves…
Nitration is one of the most established yet challenging reactions in the chemical industry. It has been practiced for more than a century, but nitration accidents and scale-up failures continue to occur. Regulatory pressure in China has also increased. China’s…
Glycolonitrile A Key Bulk Agrochemical Intermediate and Its Transition Toward Greener Production In the fine chemical and bulk agrochemical industries, large-scale markets are often supported not by highly specialized heterocyclic compounds but by basic nitrile intermediates. Glycolonitrile has a significant…
