Introduction Searches for “sodium ferrocyanide production process” or “how sodium ferrocyanide is produced” often lead only to reaction equations. In industrial production, however, the process must integrate cyanide-containing feedstocks, complexation reactions, solid-liquid separation, evaporation and concentration, controlled crystallization, and mother…
Meet Us in Shanghai and Explore the Future of the Industry From September 15 to 17, 2026, the 23rd China International Chemical Industry Fair (ICIF China 2026) will be held at the Shanghai New International Expo Centre.As a process intensification…
Introduction When searching for carbon disulfide production process or methane-sulfur carbon disulfide technology, most discussions focus on yield, energy consumption, and safety. However, a co-production process must address another critical question: Can the by-product hydrogen sulfide be consistently purified and…
One of the most critical steps in heat exchanger selection is estimating the heat duty correctly. If the heat duty is overestimated, the exchanger becomes oversized, increasing both capital cost and footprint. If it is underestimated, the required process conditions…
Hydrogen cyanide (HCN) has a normal boiling point of approximately 26°C, making it highly toxic and extremely volatile. As a result, HCN production facilities are typically designed around the principles of closed operation, continuous processing, and minimal hazardous material inventory,…
A battery-grade ethylene carbonate (EC) purification retrofit jointly delivered by Shanghai DODGEN Chemical Technology Co., Ltd. and Shida Shenghua (Quanzhou) Co., Ltd. has been selected as a national low-carbon and energy-saving case by China’s Ministry of Industry and Information Technology…
On July 1, 2026, GB 38031-2025, Safety Requirements for Power Batteries for Electric Vehicles, officially came into effect in China. Under the new Chinese national standard, the requirement that a battery must not catch fire or explode after thermal runaway…
¿De dónde proviene la mezcla si no hay piezas móviles? Un mezclador estático se instala directamente dentro de una tubería de proceso continuo y contiene una serie de elementos de mezcla fijos. A medida que el fluido fluye a través de estos elementos, el flujo axial original…
Definición: La colorimetría es una técnica analítica que se utiliza para determinar la concentración de una sustancia en una solución mediante la medición de la intensidad de su color. Se basa en el principio de que los compuestos coloreados absorben longitudes de onda específicas de la luz, y el…
Definición: Un electrolito es una sustancia que produce iones conductores de la electricidad cuando se disuelve en un disolvente, se funde o se encuentra en estado sólido. Estos iones permiten la conducción de la corriente eléctrica a través del medio. En ingeniería química y electroquímica, los electrolitos son esenciales…
