  • Mixing Solutions and Slurries -- Effectively, Economically and Safely

    Effectively mixing liquids and solids to create an optimal slurry is one of the perpetual challenges in the chemical industry. This case study demonstrates how an eductor-based mixing system can effectively handle a wide range of materials, utilizing the least amount of floor space, energy and human resources to achieve an optimized process. In addition, the eductor mixing system offers increased efficiencies over a conventional system of mixing by allowing solutions and slurries to be made on demand – as opposed to pre-mixed in large holding tanks. Another important benefit is the system limits exposure to operators, and mitigates issues of delivering solid material in a large vapor space. The design flexibility of an educator-based mixing system offers a high level of customization.

  • No More Risky Business With Virtual Patching

    Patching process control system software to remove security vulnerabilities is fraught with risk. System issues can be the result of installing a patch, but a system is also vulnerable without patching. Fortunately, virtual patching can improve the process and raise the system’s security at the same time.

  • OPC: The Ins and Outs to What it’s About, The Every Man's Guide to OPC

    The Every Man’s Guide to OPC is an easy-to-read overview of the most popular industrial open connectivity standard - OPC. This paper introduces the main idea behind OPC, shows why OPC is different from conventional (often proprietary) communication protocols, and explains how OPC helps overcome the limitations of such native protocols. Next, the paper explains what the building blocks of OPC are (OPC Clients and OPC Servers) and how they work together to make data-sharing possible.

    This guide to OPC helps readers of all technical levels quickly grasp what OPC is and how they can use it.

  • Optical System Sets New Standards in Oxygen Measurements

    Optical Dissolved Oxygen Measurement in Power and Boiler Applications

    Over the past decade a few trends have started to gain pace within the industry, driving a change in instrumentation requirements for operations managers and plant chemists:

    • Maintenance and operations budget cuts have resulted in fewer plant personnel, forcing plant staff to optimize their workload even further
    • As the cost of building new power and boiler systems increase, many operators now look to plant life extensions as a solution to bridge gaps in production capacity at a lower investment premium

    These trends have changed the requirements in these applications. Starting from these trends, this article analyzes the options for oxygen measurements that are precise, reliable, stable, and above all require low to zero maintenance.

  • OSHA & NFPA Compliant: Keeping Your Plant Safe

    In March 2008, OSHA reissued its Combustible Dust National Emphasis Program (NEP) notifying approximately 30,000 companies nationwide that they will be targeted for inspections over the next few years. Mettler Toledo recognizes that many manufacturers are not up-to-date on the latest hazardous area compliance regulations or may not know that their industry is subject to those regulations. Don't wait until your facility receives a surprise visit from OSHA or worse yet, for a catastrophic incident to occur. Take the proactive approach to addressing the "hazardous area advisory level" in your facility.

  • Particle Image Understanding – A Primer

    This paper will discuss the use of pattern recognition techniques to identify and differentiate different particle types contained in a heterogeneous solution. This application involves imaging the microscopic particles in real-time as they flow in a solution, segregating each individual particle as a separate image, and then applying pattern recognition techniques to differentiate the individual particle types.A framework for discussing the complexity of a pattern recognition operation in this application will be proposed, along with some specific examples showing how this framework applies.

  • Passive techniques for reducing input current harmonics

    Harmonics can have a detrimental effect on power generators and other sensitive electrical equipment for the user and utility alike. The number of adjustable speed drives (ASDs) has increased significantly in the past decade. Their contribution to the total electrical load of a power system is significant and cannot be neglected. This white paper discusses various passive techniques for reducing input current harmonics.
