  • Filtering Samples to On-Line Process Analyzers

    Increasingly precise process control strategies, often linked to computer control, have accelerated the use of sophisticated on-line chemical composition analyzers in plant applications. Instruments such as gas and liquid chromatographs, ion chromatographs, laser optic instruments, atomic absorption instruments and specific ion analyzers, which were rarities in laboratories ten years ago, are now found routinely in plant settings.

    While continuing miniaturization and “rugged-ization” of the electronics are making the instrumentation circuitry more tolerant of the plant environment, the level of contamination in plant samples compared to laboratory samples continues to plague the process. This white paper reviews  the factors in plant operation that may affect the deliverability of acceptable samples  and provides guidelines for addressing these factors.

  • Special Report: Protect Process Control Systems

    In the decade before Stuxnet attacked process control systems in Iran, there were just five known supervisory control and data acquisition (SCADA) vulnerabilities for all control systems in the world, according to the U.S. Department of Homeland Security's Industrial Control Systems Cyber Emergency Response Team (ICS-CERT). In 2011, the year after Stuxnet, that vulnerability count jumped to more than 215. Last year, it reached 248. No surprise then that Chemical makers are increasingly focusing on protecting their process control systems from intrusion both from the inside and outside. In this Chemical Processing Special Report: Protect Process Control Systems, we take a look at:

    • How to better protect your control system - "Defense in depth" is crucial, and new and maturing technologies may help
    • Cyber Security Challenges - learn about countermeasures to protect control systems
    • Case Study: A vulnerability assessment reveals critical gaps in the security of a natural gas pipeline
    • How to mitigate security risks in legacy process control systems  - several steps can help protect against threats and extend the life of legacy equipment

  • The Perils of a DIY Distributed Control System

    The debate over the virtues of DCS vs. PLC has been ongoing since these two architectures came into existence 40 years ago. For certain industries, a distributed control system (DCS) provides substantially more value as the basis for automating the plant than a programmable logic controller (PLC)-based system. As functionality differences narrow and price points align, the debate over these virtues is getting more intense and the arguments for and against each system are getting more and more murky. This white paper discusses the “Top Ten” issues to consider when evaluating a DCS vs. building your own “DIY” distributed control system using a PLC-based architecture.

  • Process Filtration Technology: Making Informed Decisions

    Solid-liquid separation is an instrumental part of chemical processing. To separate the solid particles, filter media made of textile or metallic materials and of composite materials are used as the basis for the filter cake. Often there will also be a washing process to improve the purity of the filter cake or to increase the yield of the liquid phase. Solid-liquid separation can be carried out in continuous or batch operation. There are many factors for selecting the right process filtration system for your specific application. This white paper reviews methods for identifying the right process filtration technology for your application and highlights case studies illustrating the methods discussed.

  • Special Report: Making the Most of Migration

    Perhaps the most critical challenge facing the automation industry is that of aging control systems at or near the end of their product lifecycles. A legacy control system can suffer from technical, functional or supply obsolescence. With a well-planned and executed control system migration, however, plants can improve availability and reliability, while increasing production flexibility. In this Chemical Processing Special Report: Making the Most of Migration, we take a look at: Obsolescence planning – addressing concerns and planning for a successful evolution strategy; Restoration Possibilities – how new tools and innovative methods support and breath new life into aging distributed control systems; DCS Migration; More!

  • CP eHandbook: Wireless - Plants Benefit from Wireless Technology

    For chemical processors, changing process conditions demand quick responses in order to keep processing effective and to keep processes running properly. For processes undergoing such changes, accurate and timely measurements, such as vibration monitoring, redundant tank level measurement and steam header temperature profiling can be difficult to collect. In well-established plants it’s both very expensive and time consuming to get measurement points online using conventional wired instrumentation. Many processors are now turning to wireless devices that can supply data from numerous points that never could have been justified otherwise. In this Chemical Processing Wireless eHandbook we take a look at wireless technology solution successes:
     
    ** How installing a wireless pH analyzer for crucial insights on seal integrity provided Fuji Film with a low-cost monitoring solution for protecting a pricey pump
    ** How one of the world’s largest producers of chlorine, caustic soda and vinyl chloride embraced wireless technology and achieved operating economies and more efficient control of its chemical processes

  • Chemical Processing Flow eHandbook: Monitoring Flow

    The purpose of installing a flowmeter system is to accurately measure flow in a reliable manner. Issues related to physical properties, process parameters, electronic features and interconnections are often given much consideration. Relatively little emphasis, however, is given as to how well the flowmeter will perform its intended purpose. Adding to the confusion are the differences in how performance is expressed and the incomplete nature of the available information. Nevertheless, the quality of flow measurement should be a concern. This Chemical Processing eHandbook takes a look at technologies and solutions affecting flow including: * Coriolis meters - steps you can take optimize performance when faced with entrained gas * Magmeters -- why you should consider using them * How to achieve effective flow control with centrifugal pumps
