Wireless sensors, as a part of the Industrial Internet of Things (IIoT) set of technologies, are finding new applications due to their ease of installation and commissioning. Many of these applications fall outside of the traditional monitoring and control applications managed by the industrial control systems in the manufacturing or production facility. These applications can […]

New technologies usually become more broadly adopted as multiple suppliers adopt the technology and provide interoperability. Standards efforts help to define common requirements into a specification for suppliers to follow in their technology development programs. Today, industries such as warehouses, airlines and others employ radio-frequency identification (RFID) technology for increased productivity. The use of RFID […]

According to Wikipedia, superheated steam is steam: …at a temperature higher than its vaporization (boiling) point at the absolute pressure where the temperature is measured. It has: …tremendous internal energy that can be used for kinetic reaction through mechanical expansion against turbine blades and reciprocating pistons, that produces rotary motion of a shaft. The value […]

Because they directly touch the process flow, control valves play a significant role in the stability, robustness and variability in the process. One bad-acting control valve can create large problems for safe and reliable operations. At last week’s AIChE Spring Meeting, Emerson’s James Beall presented Specifying Control Valve Performance to Achieve Desired Process Performance. In […]
