Instrumentation

In industrial settings where hazardous gases, vapors, or dust may be present—commonly referred to as hazardous areas or explosion-proof zones—electrical and instrumentation installations must strictly comply with safety regulations to prevent ignition sources. A common question arises during design and installation:Is the use of flexible conduit mandatory in explosion-proof areas? The answer is: It depends […]

Chemical instrumentation plays a crucial role in industrial automation, especially in chemical plants, where precise measurement and control are essential for safety and efficiency. The tools and equipment used for installation, calibration, maintenance, and repair of chemical instruments can be divided into general-purpose tools, specialized tools, measurement devices, and auxiliary equipment. This article details these

When Carbide Dust Meets Acetylene Gas: Risks and Protective Measures In the chemical industry, carbide dust and acetylene gas play crucial roles in various production and manufacturing processes.

The representation of pH has long intrigued learners of chemistry. While the scientific community universally accepts this notation, the reasoning behind the lowercase “p” and uppercase “H” is often misunderstood. Let’s explore this topic in depth, starting with the basics of pH, its origins, and why this specific notation is used. 1. What is pH?

In the petrochemical industry, crude benzene may not be the most expensive raw material, but it is certainly one of the most unpredictable variables in process control. It appears throughout key stages such as aromatization, hydrotreating, and storage & transport. Once out of control, crude benzene can impact not only production efficiency but also plant

1. Introduction With the rapid development of the lithium battery industry, lithium sulfate (Li₂SO₄) and ferric sulfate (Fe₂(SO₄)₃) have emerged as essential chemical compounds in the supply chain. They serve not only as precursors for battery materials but also play critical roles in metallurgy, wastewater treatment, and catalysis. Precise measurement of their purity and composition
