  • Powder eHandbook: Preclude Powder Problems

    Process design and process safety are critical considerations in chemical production and processing. With design and safety paramount at the outset of any new development or equipment retrofit, firms can minimize risk exposure, maximize productivity and position themselves to remain compliant and competitive.

Combustible dust can pose a hidden hazard when accumulation occurs in unseen locations such as in mechanical spaces, above false ceiling, ventilation systems and dust collection systems. In this Chemical Processing Powder eHandbook, we take a look at strategies and solutions for mitigating combustible dust hazards including:

    • Identifying hidden hazards - a case study outlining how a facility finds danger from accumulated dust and effectively addresses it

  • 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

  • Special Report: Avoid Common Vessel Errors

    Welded vessels play a key role in most processes. However, few plants now have in-depth expertise in materials selection, fabrication and design of such vessels. As a result, plant staff often make errors that can be costly as well as compromise the suitability and life of the vessel. This three-part special report provides practical pointers that can help you avoid common mistakes and get the most appropriate, durable and cost-effective vessel.

     

    • Part 1 looks at a dozen important factors to consider in materials selection, including metal selection and appropriate use of corrosion allowances and coatings. It includes pointers gleaned from first-hand experiences that can help you avoid costly mistakes and delays.
    • Part 2 provides tips on how to avoid delays and achieve savings in the fabrication process. It also covers techniques that can improve vessel reliability and thus forestall costly repairs down the road.
    • Part 3 gets into design issues. It condenses the 5,000+ pages of the ASME Boiler and Pressure Vessel Code into a simple guide when specifying vessels, heat exchangers and tanks. It focuses on 10 key factors.
