  • What's the driving force behind the significant improvement in octanol production efficiency?
    What's the driving force behind the significant improvement in octanol production efficiency?
    In the complex processes of industrial production, precise measurement and control are crucial for ensuring stable and efficient operation. Octanol production, as a vital link in the chemical industry, places extremely high demands on the accurate monitoring of various process parameters. From raw material proportioning to reaction monitoring, from finished product storage to transportation scheduling, accurate measurement is key to maintaining the stable operation of the entire production chain. However, the octanol production process is complex and operates in harsh environments, often rendering traditional measuring equipment inadequate.

  • Steel plant denitrification project upgrade, EGE Instruments provides protection!
    Steel plant denitrification project upgrade, EGE Instruments provides protection!
    Driven by the "dual carbon" goals, the steel industry is accelerating its green transformation. Steel production generates waste gas containing pollutants such as sulfur dioxide and nitrogen oxides, which, if directly emitted, will cause serious environmental damage. Therefore, a steel plant in Shandong Province launched an ultra-low emission treatment project for sulfur dioxide and nitrogen oxides, and constructed a full-process monitoring system by introducing YIGEQI brand intelligent instruments. This successfully improved denitrification efficiency, reduced ammonia slip rate, and optimized energy consumption, providing a replicable benchmark case for the industry.

A Never-Ending "Breeze": How the Omnidirectional Purge System Protects the Accuracy of Radar Level Gauges

The universal purging radar level gauge is essentially an integration of a radar level gauge and a flexibly directional clean gas purging system. Its design philosophy is: "Proactive defense, offense as defense." By continuously spraying clean gas onto the radar antenna surface, it actively prevents contaminants from adhering, thereby ensuring the stable operation of the radar's core measurement functions in harsh environments.
