Acidity is a critical parameter in the chemical process industries, and accurate measurements of pH can be important indicators for process quality control. A refreshed understanding of pH measurement can help to overcome process-specific challenges to measurement and to select the pH measurement devices that best meet the needs of the process. Further, a review of the temperature dependence of pH...

To date, determination of the shear forces exerted on vessel walls by moving fluids has required inferring the value from other measurements. Now Lenterra Inc. (Newark, N.J.; www.lenterra.com) has introduced the first instrument capable of direct measurement of wall-shear forces without process flow interruption. The instrument, known as the RealShear sensor, also allows operators to measure fluid...

The Brinkman method is one of several approaches used to predict the effective viscosity of oil-water mixtures, and is effective in simulations when one or the other phase is dominant. However, a significant level of uncertainty exists in mixtures where the oil and water levels are comparable. Engineers from software developer AspenTech (Burlington, Mass.; www.aspentech.com) have applied a proprietary...

Gold catalysts have been shown to have superior activities for oxidation reactions, especially at low temperature, compared to other metal-based catalysts. But the high price of gold makes it necessary to develop Au catalysts with ever-higher activities, reducing the amount of Au needed. A promising step in this direction is a new type of catalyst developed by Professor Naoki Toshima and his research group...
