In chemical processing, distillation columns such as de-lightening columns are vital for separating light components from products. These columns often feature configurations with total reflux, where top light components exit as non-condensable gases and condensed liquid is fully returned. Examples include stabilizing columns, stripping towers, desorption towers, and de-lightening columns. This article focuses on de-lightening […]

Introduction Profinet, a leading industrial Ethernet standard, has become an integral part of modern industrial automation. With the increasing demand for flexibility, mobility, and scalability in industrial environments, Profinet Wireless (Profinet over Wireless) has emerged as a crucial technology to address these needs. By leveraging wireless communication technologies such as Wi-Fi, 5G, and Bluetooth, Profinet

In industrial process control and safety systems, proper configuration of alarm and interlock setpoints is crucial for ensuring operational safety, equipment protection, and efficient production. A common design principle is that alarm setpoints should be set lower than interlock setpoints to provide early warning before automatic protective actions occur. However, is it always unreasonable for

In complex and precise industrial system architectures, Safety Integrity (SI) serves as the cornerstone for safeguarding personnel, assets, and the environment. The concept of “failure” within this context is a critical node that demands comprehensive and in-depth understanding. Accurate identification and detailed classification of failures not only facilitate the stable operation of systems but also
