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…
Where Does the Mixing Come From If There Are No Moving Parts? A static mixer is installed directly inside a continuous process pipeline and contains a series of fixed mixing elements. As fluid flows through these elements, the original axial…
Definition Colorimetry is an analytical technique used to determine the concentration of a substance in a solution by measuring the intensity of its color. It is based on the principle that colored compounds absorb specific wavelengths of light, and the…
Definition An electrolyte is a substance that produces electrically conductive ions when dissolved in a solvent, melted, or in solid state. These ions enable the conduction of electric current through the medium. In chemical and electrochemical engineering, electrolytes are essential…
