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

1. Introduction Advanced Process Control (APC) is a technology designed to enhance the performance, stability, and efficiency of industrial processes. By utilizing modern control theories, computational methods, and sensor technologies, APC provides optimized process control, particularly in industries where traditional methods struggle with complex dynamics, multi-variable interactions, and strong coupling effects. APC has been a

Hazardous industrial environments — such as chemical plants, oil refineries, pharmaceutical production lines, and grain processing facilities — are often at risk of explosions due to the presence of flammable gases, vapors, or dust. In such areas, proper electrical grounding (earthing) is not just a safety feature — it is a regulatory requirement that forms

1. Introduction Material flow issues such as jamming, clogging, and material adhesion are common problems in industrial production. These issues can significantly impact production efficiency, cause equipment damage, and increase downtime. Therefore, understanding their causes, consequences, and potential solutions is crucial for maintaining a stable and efficient production process. 2. Definitions and Key Differences 2.1
