  • eHandbook: Leverage These Level Best Practices

    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. In this Chemical Processing Level Instrumentation eHandbook, we discuss best practices for level management including:

    • Interpret Level Readings Right – how the type of instrument can make a big difference in deciphering measurements
    • Choose the Correct Level Sensor – key considerations and questions for identifying the most appropriate choice
    • Customize Your Level Detection – a myriad of options help you achieve optimal level indicator performance

  • 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

  • eHandbook: How To Fight Flow Challenges

    In addition to flow pressure, volume and material state, achieving and maintaining desired flow performance depends upon properly addressing some complicated design and operational issues. In this Chemical Processing Flow eHandbook, we identify strategies and solutions for aerodynamic, technical, mechanical and economic constraints including:
     
    Hydrogen systems – Inspections and tests for ensuring safety and flow
    Axial compressors – achieving and maintaining desired performance
    Fight flow recirculation – why the phenomenon occurs in centrifugal pumps and how to correct it

  • Chemical Processing’s eHandbook: Follow These Best Flow Practices

    Corrosion, leak detection and mitigation, flow pressure and volume are all factors that maintenance managers and other decision makers need to contend with as they manage flow at their chemical processing plants. In this Chemical Processing Flow eHandbook, we delve in to solutions and strategies for managing these challenges including:

    • Leak management - treat them as calls for action against the underlying problem
    • VFDs for centrifugal pumps - such drives may provide energy savings and avoid operating problems
    • Dealing with corrosion - piping made of high-performance plastic provides unmatched performance and longevity
    • Ceramic in electromagnetic flow meters - material used for measuring tubes offers high performance, longevity and a host of other benefits

  • 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

  • A Treatise of Filter Cake Washing Mechanisms in Pressure and Vacuum Filtration Systems

    During many chemical operations, cake washing is required since no filter system can remove all of the mother liquor by pressure or vacuum dewatering only. The topic of how to most efficiently wash the cake is important. This article introduces pragmatism into cake washing theory and will help engineers during their decision-making processes.

  • Inerting and Blanketing: New Cost-efficient Solution with Polarographic Sensors

    In this white paper, we review the new possibilities offered by measurement systems based on polarographic technology. Unlike other systems, polarographic sensors are built directly into the process gas stream, eliminating the need for cumbersome gas sampling and conditioning systems. Further, polarographic sensors require very little maintenance.
