  • Chemical Processing’s eHandbook: Improve Flow Management

    Half the battle with flow is choosing the proper equipment. Indeed, flow meter selection and specification is crucial. With the wrong choice you’ll be floundering or worse. In addition, process engineers identify “oversizing” as the number one control valve problem. In this Chemical Processing Flow eHandbook, we identify tips to improve flow including:

    • How to match the flow meter to the service
    • How to handle more flow
    • How to properly size control valves
    • How to tackle biogas flow measurement challenges

  • 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

  • eHandbook: Take the Pressure Off Your Process

    When thinking of the processing of chemicals, we think of any activity including storing, using, handling, manufacturing, or moving chemicals at a site, and any combination of these activities. A common state in many of these activities is the flow - or rate - at which the chemicals are moving through a process. Accurately measuring flow can be a challenge for many chemical processors since so many factors can influence the chemical properties and subsequently the  rate of flow. In this Chemical Processing Pressure eHandbook, we discuss considerations for flow management including:

    • Pressure transmitters -  how noise can pinpoint process problems
    • The use of orifice plates -  how insufficient flow conditioning often undermines measurement accuracy
    • Robust Inferential Sensors - easier-to-develop-and-maintain sensors offer significant benefits for chemical processes

  • Level eHandbook: Tackle Level Management Challenges

    Level measurement, which is the detection of the phase split between vapor/liquid, liquid/liquid, vapor/solid and even liquid/solid, is a key parameter in the operation and control of modern industrial processes. A reliable outcome depends on the phase conditions being relatively consistent under all process conditions. Unfortunately, the importance of level control isn’t always understood. Failure to measure level reliably has resulted in some of the most serious industrial accidents, including those at the Buncefield, U.K., fuel storage depot and BP’s Texas City refinery. In this Chemical Processing Level Management eHandbook, we discuss best practices for level management including:

    • How to Select the Right Liquid Level Sensor - It’s important to consider a variety of factors when choosing the type of technology
    • Multivariable devices - gain operating and maintenance benefits
    • Achieving level control with dP transmitters - it appears simple but really is not

  • 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.
