This general installation and commissioning plan is designed to ensure the DCS system operates smoothly and reliably after deployment. 2. Preparation for Installation 2.1 Equipment and Material Preparation Verify […]

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

Abstract Supervisory Control and Data Acquisition (SCADA) systems have evolved significantly over the past few decades. Initially serving as basic data collection tools, they have transformed into modern platforms with advanced analytical and integration capabilities. With the rise of the Industrial Internet of Things (IIoT) in the last 20 years, SCADA technology has rapidly advanced

Emergency stop buttons (E-stop buttons) are critical safety features on industrial and commercial equipment. Their purpose is to immediately stop a machine or process during an emergency to protect personnel, equipment, and the surrounding environment. However, there is often debate regarding whether the protective cover of such buttons should be locked or sealed. This article

Boiler drum level transmitters play a critical role in maintaining the safe and efficient operation of a boiler system. These instruments measure the differential pressure across the water and steam sides of the drum to determine the water level. Depending on the installation orientation of the transmitter, forward or reverse, the signal interpretation in the

Introduction In industrial automation, safety and process control are managed by distinct systems designed for different purposes: the Distributed Control System (DCS) and the Safety Instrumented System (SIS). Understanding whether safety interlocks can be implemented through DCS requires a deep dive into their fundamental differences, capabilities, and safety standards. 1. Distinction Between DCS and SIS

Introduction In petrochemical production processes, the Safety Instrumented System (SIS) interlock logic is a crucial safety measure ensuring the safe operation of industrial processes. Various SIS interlock configurations, such as 1-out-of-1 (1oo1), 2-out-of-2 (2oo2), 2-out-of-1 (2oo1), and 3-out-of-2 (3oo2), are commonly used. Recently, a new configuration, 4-out-of-4 (4oo4), has been proposed. This article explores the
