Twenty years ago, fire swept through the Piper Alpha oil rig in the Scottish sector of the North Sea. Panic and confusion were the order of the day as the doomed installation buckled into the frigid water.
The FT4 Powder Rheometer was originally designed to characterize the rheology, or flow properties, of powders. This remains a primary function today, but the instrument, accessories, and methodologies have been continuously developed to the point where the FT4 is now considered a universal powder tester.
Sauereisen offers a comprehensive selection of corrosion-resistant materials for new construction and restoration applications. Organic materials offer low permeability and withstand chemicals from both sides of the pH scale.
Fourier transform infrared (FTIR) spectroscopy is an accepted and well-known technique by the EPA to measure hydrogen chloride (HCl). Over the past 10 years, HCl by FTIR has been utilized successfully at many cement kilns and other incineration technologies using EPA Method 321 or 301.
An application report is available from Anton Paar that describes how density and sound velocity are used to determine the concentration of sulfuric acid and oleum in various industrial processes. The report covers an overview of sulfuric acid production, typical installations, theory of measurement, along with a summary of benefits of measuring on-line.
Measuring flow of a gas or liquid through an industrial process often presents a series of technical challenges, but it is often also a decision that can impact business. Well over a dozen technologies are used as the basis of measuring flow — each with its own strengths and weaknesses.
