In the powder chemical industry, combustible dust explosions are rare but highly destructive “black swan” events. According to Dust Safety Science, between 2016 and 2020, the United States averaged approximately 31.8 dust explosions per year (excluding dust fires), resulting in numerous injuries and significant economic losses annually. I. A Massive Explosion Triggered by a Small […]

In modern industrial boilers, there is an often overlooked yet crucial component — the water-cooled wall. While many are familiar with the term, do you know its exact function and significance? In fact, the water-cooled wall not only serves as the boiler’s “protective barrier” but also plays a vital role in steam generation. 1. The

In the refining industry, there are tens of thousands of advanced control systems in operation, and when extended to sectors such as chemicals and power, the global number of such systems could reach hundreds of thousands. While offline mechanistic models exceed the scale of advanced control applications, real-time optimization based on steady-state mechanistic models is

In the oil, chemical, and energy transportation industries, the term “loading arm” (also known as liquid unloading arms) is commonly encountered. It is an indispensable piece of equipment in liquid material handling systems, widely used for transporting flammable, explosive, or toxic liquids due to its safe, efficient, environmentally friendly, and sealed loading and unloading capabilities.

The core logic behind the source calibration method is to trace the origin of data (such as original collection devices, reference documents, or authoritative data sources) and verify its accuracy by comparing it with a “source standard.” This method is especially suitable for data types where the origin is traceable and there is an objective

An outstanding chemical instrumentation technician is defined by a combination of solid technical knowledge, process adaptation, safety compliance, and efficient collaboration. Excellence in this field requires a multifaceted approach, focusing on continuous improvement across several areas. Below are key directions for becoming an outstanding technician: 1. Mastering Technical Skills: From “Basic Understanding” to “Expertise” 1.1

In engineering projects, the intersection of process and electrical instrumentation design often becomes a hotspot for issues. From installation interfaces to instrument gas leaks, from design defects in complete sets of equipment to the “three-proof” requirements for control cabinets, these seemingly minor details can lead to significant risks during construction. Why do these problems keep

In high-risk environments such as petrochemical plants, gas stations, tunnels, and laboratories, toxic and combustible gas detectors serve as the first line of defense for both personnel safety and the stable operation of equipment. So, do these detectors require verification or calibration? What is the difference between these two processes? Who is responsible for them,

Instrument failures can be complex and difficult to diagnose immediately. It’s important to stay calm and analyze the situation step by step. The faults can generally be divided into three sections: on-site detection, intermediate transmission, and terminal display. Seasonal factors, such as preventing high temperatures in summer and freezing in winter, should also be considered.

As an instrument technician, it’s essential to learn how to proactively reflect on your work, summarize your experiences, and improve your maintenance skills. This process is key to transforming repetitive tasks into expert-level capabilities. Below is a comprehensive framework that moves from “reflection” to “improvement,” which you can apply based on your own experiences. Part
