Pressure-relief solutions are commonly used in the chemical process industries (CPI) to ensure safe working environments for personnel and to protect equipment and assets. Relief valves (RV) and rupture discs (RD) are the most commonly used pressure-safety devices and are…
In the past, words such as “unproven,” “risky” and “expensive” may have come to mind when chemical processors considered wireless technology. However, today’s wireless solutions address these previously perceived limitations. In fact, wireless solutions are quickly becoming a must-have technology…
Existing chemical process industries (CPI) facilities possess years, if not decades, of legacy engineering information. The data exist in a myriad of formats and are typically siloed across multiple systems and locations. In cases where the engineering data are either…
A dual-sensor temperature transmitter with HART protocols Invensys Foxboro The RTT80 temperature transmitter (photo) offers signal reliability, longterm stability, high precision and advanced diagnostics. The RTT80 is a mid-tier, two-wire temperature transmitter available with HART (and soon to be released…
Effective level measurement in the chemical process industries (CPI) helps maintain material inventory at economic quantities, improves product quality and maximizes plant output by avoiding spills and process upsets. When they are incorrectly matched to their application, level-measurement devices can…
Dilute-phase pneumatic conveying systems must be operated in a certain sequence and have sufficient instrumentation and operating controls to assure reliable operation and prevent problems. This article discusses two subjects that are important for successful dilute-phase conveying. Discussed below are…
Corrosion to the external surface of process piping and vessels that is hidden under the insulation is referred to as corrosion under insulation (CUI). Aging piping and equipment in chemical plants and petroleum refineries have made CUI detection and assessment…
The chemical processing industries (CPI) rely heavily upon the use of sensors to measure everything from weight to temperature to pH to pressure. Because sensors are used for measurements that affect critical processing elements, such as quality, efficiency and safety,…
The Sitrans FC410 (photo) is a new Coriolis flowmeter that features a measuring accuracy of 0.1% of flowrate. Weighing only 10 lb, this compact meter communicates with all common process control systems and can be integrated easily into both existing…
The latest models of Professional moisture analyzers from this company feature USB, Ethernet and WLAN connectivity for easy data transfer. Measurement results, displayed by an instrument on the factory floor, can be sent directly to a regular printer anywhere on…
