This column is based on “Cyclohexane from Benzene and Hydrogen – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/cyclohexane-production-cost. Cyclohexane is a relatively stable cycloalkane, present in crude oils in concentrations of 0.1–1.0%. This cycloparaffin…
Differential-pressure (DP) level measurements are widely used in chemical and petrochemical facilities, thanks to their reliability and ease of use. Recent advances are making them even more reliable and easy to use Differential pressure (DP) level-measurement technology (Figure 1) is…
This company’s Process Water Recycling Plant (photo) is a fully automated standalone unit that enables recycling of process water from mining operations. The plant is specifically designed for concentrator plants, which dewater tailings and recycle the water back to the…
Viscosity, power consumption, commercial availability and lifecycle cost analysis are all important considerations in pump sizing. An automated spreadsheet method helps engineers take those factors into account in centrifugal pump selection Many aspiring chemical engineers enter industry after university study…
The KRAL Smart Solution (photo) is a compact electronic unit to which a Volumeter flowmeter is connected. The Smart Solution processes the signals that the flowmeter generates with its integrated sensors in such a manner that measured values are available…
Impact Plus is a new platform designed to benchmark best practices and improve corrosion management across many industry sectors. Built as a tool for management professionals, the program gives users the option to manage their own application of the product…
Vibration screening is one of the most effective ways to detect and prevent equipment failures or downtime, but performing vibration analysis can be complex. The new 3560 FC Vibration Sensor (photo) wirelessly and remotely captures simple vibration screening data on…
This company’s Vapor-phase Corrosion Inhibitor (VpCI) Technology turns basic packaging materials like paper, cardboard boxes and plastic bags into corrosion-inhibiting tools that protect by vapor phase action without the direct application of a rust preventative or coating to the metal.…
Elastomer seals that are used in valves, pipelines, fittings or pig traps have to face exceptionally high requirements. A sudden decrease in pressure can lead to damage of the sealing, a phenomenon known as explosive decompression. The elastomer material is…
Proline 300 Coriolis and electromagnetic flow instruments (photo) have been updated for safety, enhanced measurement quality, device accessibility and GMP (good manufacturing practice) compliance for sterile processes. The flowmeters’ hygienic 316L stainless-steel housings are optimized for reliability and they have…
