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…
This company’s acid storage cabinets (photo) are specifically designed for the storage of corrosive chemicals and are available in 12-, 18-, 24-, 30-, 36-, 42-, and 48-in. widths, with a standard height of 35 in. and a standard depth of…
This company has introduced two new portable calibration machines (photo) — the PCM, with a 2,000-lb f capacity, and the BCM, with a 10,000-lb f capacity. The PCM is capable of calibrating various types of load cells, hand-held force gages,…
The Memograph M RSG45 advanced data manager DIN rail version (photo) is an intelligent remote device with extensive communication capabilities for use as an edge device for getting data to cloud-based servers, as well as general industrial internet of things…
Self-adhesive pipe labels improve workplace safety ANSI/ASME A13.1 recommends the marking of all pipes to clearly communicate their contents, to improve facility maintenance and safety. This company offers a variety of premade pipe marking labels (photo), which are ready to…
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…
Users of compressed air can take advantage of heat recovery to enhance their sustainability, improve energy efficiency and reduce system lifecycle costs Air compressors account for a considerable portion of industrial energy consumption, and facilities that employ large-scale air compression…
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 pitfalls in cost estimating that cause project overruns have been well known for decades, yet they continue to plague the CPI When I first started writing this article, I set out to summarize the mechanics of project cost estimation.…
