This column is based on the report “Polychloroprene Production – Cost Analysis,” published by Intratec. It can be found at the following URL: www.intratec.us/analysis/polychloroprene-production-cost. The need to find a substitute for natural rubber during World War II boosted the development…
Computer-generated simulations of distillation processes are often validated experimentally. This reference discusses three concepts that influence comparisons between experimental results and simulation predictions: vapor-liquid equilibrium (VLE) of the components; relative liquid-to-vapor flowrates (L/V ratios in the column); and vapor-liquid contactor…
The RV Series of rotary variable differential transformer (RVDT) position sensors (photo) offer highly accurate angular displacement measurement of rotating elements, such as quarter-turn ball and butterfly valves, actuators, throttlers and tensioners. With a shaft that rotates a full 360…
With the onset of new environmental regulations, turnaround teams must look to temporary vapor-control strategies to ensure compliance during non-routine operations Turnarounds are one of the most anticipated and time-intensive events in a plant’s cycle, and are an essential part…
The recommended velocities for fluids’ transportation must be updated periodically to obtain the optimum value of the pipe diameter in the current economic conditions To arrive at the optimum diameters for pipes, the heuristic criteria of recommended velocity has been…
This methodology can be used not only for laminar flow, but also for the complete turbulent flow region In recent decades, the impact of energy costs on the transport of fluids has led to a significant reduction in fluid velocity…
The LFV Series 8000 two-way inert solenoid valve (photo) is a miniature device whose small size ensures a more compact instrument footprint and means less fluid is needed, enabling closer valve spacing. These two-way, chemically inert, isolation-style valves provide an…
This company now offers Virtual Lockout-Tagout (vLOTO) capabilities with its Connect Power User Plans. vLOTO allows companies to control remote access to equipment, ensuring the safety and security of workers and equipment during critical operations. If a worker needs to…
This company has designed a new version of its E-Scale series of IIoT-connected bench scales (photo). With a direct industrial network connection via EtherNet/IP, Profibus-DP or Modbus protocols, the IIoT-ready scale base includes an integrated weight processor. E-Scales are suitable…
AllAssets is a new software-as-a-service (SAAS) platform for asset performance management that enables optimization of inspection and maintenance activities. Chief among the features offered by AllAssets is robust integration with enterprise resource planning (ERP) systems from a variety of providers,…
