In the chemical process industries (CPI), multiphase flow regimes in reactors, bubble columns, pipework and elsewhere in plants determine process efficiencies and safety. As a result, a considerable number of intrusive and non-intrusive techniques have been developed to recognize phase fractions. However, such techniques are very expensive and complex (such as tomography) or provide only localized...

    Most assets depreciate, losing value over time as a result of wear and tear, age, or obsolescence. Corrosion, like depreciation, results in the often hidden cost of a non-cash expense — measurable in terms of reduced operating life — that reduces the value of assets. Many engineers in the chemical process industries (CPI) see corrosion on a “straight-line basis” in...

Researchers at the University of Warwick (edlinks.che.com/6896-540) and Leicester University (both U.K.) have used artificial nasal mucus to significantly enhance the performance of odor-sensing devices (electronic noses), which are used for quality control in, for example, the food industry. By coating the sensors with a mix of polymers that mimics the action of the mucus in a natural nose, the electronic...

    Portable and fixed detectors for toxic and flammable gases are offering more choice and better value for the money, say experts, thanks to technology developments and strong market competition. In Europe, competition triggered by consolidation in the last five years has propelled the market out of the doldrums of the last couple of decades, according to a recent report from market consultancy...

    The beauty of fiber-optical spectroscopy is that small, inexpensive devices with no moving parts bring their capacity to where the samples are, rather than the other way round. As a result, spectra can be recorded in almost real time, which means that information about composition, concentration and other chemical parameters can be gathered alongside of temperature, pressure and flowrate. The...
