  • Chemical Processing Special Report: Secure plan(t)

    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 (Figure 1). 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: Secure plan(t), 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

  • Understanding Dust Explosion Dangers

    The unfortunate propensity of dust explosions to destroy entire facilities and claim lives is very real. Powder handling processes often are comprised of interconnected enclosures and equipment. Flame and pressure resulting from a dust explosion can therefore propagate through piping, across galleries, and reach other pieces of equipment or enclosures, leading to extensive damage. In this Chemical Processing Special Report, we take a look at the latest NFPA standards and dust explosion mitigation strategies. This Special Report covers:
     

    • Significant revisions to dust explosion standards – NFPA 654 major changes include new administrative requirements
    • How to defuse dust dangers - carefully consider and then counter risks of fire and explosion
    • Five common dust explosion misconceptions that can lead to a false sense of security

  • Powder eHandbook: Efficient Powder Process Handling

    The mechanisms of powder flow are complex. They are influenced by an array of different parameters; some relate to the particles’ physical attributes, such as size and shape, and others, such as humidity, to the system itself. Although there is a general understanding of these individual mechanisms, the multitude of interactions that govern the specific behavior of a given powder can many and in turn, affect how these powders are processed. In this Chemical Processing Powder eHandbook, we take a look at technologies and strategies for handling powders including:
    • How to Optimize Humidity for Efficient Powder Handling - too much or too little moisture can cause problems during processing and storage

  • Chemical Processing’s Level eHandbook: Best Practices for Level Management

    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

  • 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

  • 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.
