  • Digital Coriolis improves polyethylene productivity

    Page(s): 4 - 5
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (144 KB)  

    Production of polyethylene, the most used polymer in the world, typically involves flow streams containing gas and liquid, but inability to measure this two-phase flow accurately has been the source of myriad production problems. The difficulties involved with two-phase flow measurement have been linked to process interruptions, poor product quality wasted materials, and higher energy costs, any of which can sap profitability of a production run. One leading chemical producer has found a solution to the problem, using Coriolis flow measurement technology that the Foxboro unit of Invensys has developed in collaboration with flow specialists at the University of Oxford. This solution has enhanced PE production in both small and large scale operations. View full abstract»

  • My view... HYSYS deal hints at future shape of automation industry

    Page(s): 8 - 9
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (157 KB)  

    Honeywells acquisition of simulation and operator training software assets from AspenTech highlights a divergence of philosophy among process automation vendors. Honeywell was acquiring from Aspen Technology (AspenTech) the intellectual rights to the HYSYS family of modelling software and buying its Operator Training Simulation (OTS) business. AspenTech has spent the past two years trying to get off the FTC hook without actually giving up Hyprotech and, announced that it had reached a provisional settlement. The terms of that settlement were pretty much those of the deal with Honeywell announced, namely that Honeywell gets the OTS business and the intellectual property rights to HYSYS but, crucially, AspenTech retains an indefinite license to the Hyprotech products which allow it to continue to market, sell and develop them. AspenTech has also agreed not to compete in the operator training services business for three years and to provide Honeywell with source code of any new releases of the Hyprotech products.

  • Urban utilities warm up to the idea of wireless automatic meter reading

    Page(s): 10 - 14
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (345 KB)  

    While Italy's ENEL SpA heralds in the new world of automatic meter reading, the colossal utility service provider is not alone in this massive endeavour. Literally hundreds of AMR projects are being deployed worldwide from as far away as Australia and Argentina to as close as Germany and Greece. The advent of deregulation in the utility market and the technological advances in control communications has made it possible for utility service providers all over the world to take advantage of the benefits of AMR. In addition to automated meter reading, AMR systems enable load balancing and distribution, rapid identification of power faults, and remote service activation or deactivation. An AMR system can save a utility service provider million of euros per year in efficiency and maintenance fees. The key to successful wireless AMR deployment is to carefully consider the wireless technology and to put into place a long-lasting, intelligent system that meet the challenges of the residential urban metering environment by addressing interference and data reliability, and by providing long battery life.

  • A software approach to integrated machine vision

    Page(s): 15 - 18
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (287 KB)  

    The importance of image capturing and illumination notwithstanding - the evaluation software as the 'byte-cast representation' of the inspection strategy is the heart of every vision system. A particular problem of evaluation software is that its development takes place through continuous interaction with external constraints like the characteristics of the test pieces, imaging and illumination conditions. In the development of image processing software, as in other areas of software technology, two trends can be observed in the attempt to cope with these problems: i) rapid prototyping ii) component-based development. An integrated image processing system gives to the application engineer the performance of dedicated libraries, combined with the comfortable graphical environment of rapid prototyping tools and the extensibility of component-based systems.

  • Vision enabled robots have 'eyes' for you [industrial robots]

    Page(s): 19 - 20
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (157 KB)  

    Robots have traditionally been taken up more by large manufacturing firms, which could invest in both the technology and a supporting infrastructure. But, as costs continue to fall, the technology itself is changing in ways that mean robotics can benefit almost any manufacturing environment. As well as advances in robot mechanics and developments in their controllers, the integration of robots with sensors is powering a new future for new and traditional users alike. Robots are routinely rigged to incorporate proximity, touch or laser sensors, but recent advances have shown that machine vision (MV) technology can also be used with robots. A new generation of vision enabled robots is able to make decisions based on sensory feedback from their environment. They can adapt to perhaps any manufacturing scenario. View full abstract»

    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (456 KB)  

    Component based automation (CBA), the decentralized approach to automation with distributed intelligence in technological modules, is picking up speed. Component based automation clearly simplifies planning, engineering and commissioning of complex plans and reduces the time needed for the start of production by between 10% and 15%. The author discusses prospects for the future of automation with Totally Integrated Automation. TIA will be characterized by further vertical integration with Profinet, further integration of functionalities in the hardware, and further integration along the engineering flow. With the advantages of time and cost reduction, component based automation will enhance users' competitive capabilities in all sectors, thus offering a clear perspective for the automation.

  • ROSE project leads the way to better environmental monitoring

    Page(s): 38 - 41

    One family of gas detection techniques is that of Remote Optical Measurement Techniques (ROMTs). ROMTs, also known as 'open-path monitoring techniques' encompass a variety of optical techniques for detecting gaseous compounds in ambient air. Open-path instruments present a variety of methods of measuring concentrations of gases in ambient air, but they aren't frequently used because of the uncertainty of long path measurement. Some recent research has been done to better understand these challenges. The European Commission funded a project to address the lack of performance standards and to improve the understanding of the factors affecting the validity of measurements made with ROMT instrumentation. Entitled the 'ROSE' project (Remote Optical Sensing Evaluation), the consortium of partners devised a plan to assess ROMTs in a variety of real-life applications in order to understand the factors affecting performance along with a programme of modeling to assist the application of the knowledge gained.

    The field of high performance computing is undergoing a lot of changes. At the low end, supercomputers are becoming ever more affordable while, at the high end, it is becoming increasingly difficult to exploit the full potential of the most advanced hardware, given the sheer scale of the software challenges involved. There are also signs that the boundary between the worlds of the supercomputer and the desktop - traditionally very distinct - is starting to blur. Supercomputers continue to scale, with performance advancing at a rate that exceeds the rate of chip-level improvements, as characterized by Moore's law. These advances largely stem from the dramatic growth in cluster technology, which allows many processors to be closely coupled to solve large computational problems. View full abstract»
