The TW Series turbine flowmeter (photo) provides flow measurement of oils, water and chemicals with±1% of reading or better and 0.1% repeatability. TW Series turbine meters are available in flow ranges from 0.6 to 5,000 gal/min and feature 316 stainless-steel…
In boilers, silicates can volatilize with the generated steam and then form silicate glass on turbine blades, causing an imbalance. Therefore, the concentration of silicates in boiler circuits must be reduced to below 0.5 parts per million (ppm). The conventional…
Deciding whether to put a project on the fast track entails risks. Some observations are presented here to help minimize risks and maximize profits Time is money!” my mother used to tell me, whenever she caught me reading comic books…
Optimization, advanced process control and performance monitoring are possible via simulation tools Software advances, including faster computations and ease of use, are opening new doors for simulation software applications in chemical process industries (CPI) facilities, allowing processors to extend the…
The new model 700-THX-50-ARI rotary batch mixer (photo) blends abrasive materials, such as concrete, premix, mortar mix, glass, fiberglass, refractories, tungsten powder and ceramics, in 1–3 min with minimized abrasive wear or product degradation. The mixer features abrasion-resistant steel contact…
The size and size distribution of particles are important determining factors in the design and operation of many process operations involving dry particles and powders. Follow this guidance to understand the impact of these key characteristics Bulk solids are dry…
Handheld device speeds maintenance, startup efforts The AMS Trex Device Communicator (photo) uses the company’s Power the Loop technology. By removing the need for an external power supply, the device helps users work more effectivey and perform faster device configuration,…
A triple-layer, porous membrane system developed at the Functional Materials Laboratory at Eidgenössische Technische Hochschule Zürich (www.fml.ethz.ch) can be fashioned into evaporative curtains to cool and humidify indoor spaces, potentially decreasing the energy demand for climate-control systems. Juxtaposing opposite forces…
NTT Communications Corp. (NTT Com; www.ntt.com) and Mitsui Chemicals Inc. (both Tokyo, Japan; www.mitsuichem.com) have demonstrated the ability to predict, with a high precision, the concentration of gaseous products generated in a furnace. The predictions are produced in just 20…
A newly patented class of synthetic antimicrobial compounds is aimed at overcoming the limitations of existing industrial disinfectants, such as quaternary ammonium compounds and bleaches. “Bleaches are effective disinfectants on initial application, but they don’t work when they dry and…
