In Safety Instrumented Systems (SIS), Safety Integrity Levels (SIL) are crucial for ensuring that Safety Instrumented Functions (SIF) meet the necessary risk reduction requirements. This article focuses on the Layer of Protection Analysis (LOPA) method, which is widely used to determine the appropriate SIL for a specific SIF in industrial applications. Introduction to Layer of […]

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.
