  • Chemical Processing Powder eHandbook: Succeed at Solids Handling

    One of the trickiest materials to process, solids are comprised of powders or particulates, a continuous gaseous phase (usually air) and, almost always, a liquid component. Processors that handle solids know only too well the types of throughput problems that come up on a recurring basis. Clumping; effective, economical and safe slurry mixing; dust management and dust explosion risk mitigation are all very real challenges faced by processors of solids. In this Chemical Processing Powder eHandbook, we take a look at how to effectively handle solids including:
    • Clumping – the 10 most common sources of agglomeration in bulk solids and how to effectively manage them
    • Strategies for optimal slurry mixing
    • Level management detection in storage vessels
    • Dust explosion risks – how to identify and mitigate when processing solids
    • Managing solid cohesiveness with flow strategies

  • 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

  • CP Powder eHandbook: Effective Powder Processing

    As many chemical processors know, processing powders can be tricky. Powder properties can be affected if the materials are stored for long periods. Powders can be compressed, vibrated, aerated and exposed to moisture. And specific processes like granulation, blending, drying, milling, lubricating and compression put requirements on how powders can be handled. In this Chemical Processing Powder eHandbook, we take a look at how to effectively process powder including:
    • Compression dryers – the case for choosing a solution that produces optimal air quality and low energy consumption
    • GHS – understanding the requirements and what it means to chemicals processors
    • Predicting powder flow behavior
    • Vibratory screen cleaning methods
    • Fine powder flushing - eliminating a common bin-afflicting problem caused by trapped air
    • Tubular Drag Conveying Technology – an alternative to pneumatic conveying
    • Addressing dust hazards – including explosions

  • CP eHandbook: Use Energy Effectively

    Effective energy management can help achieve more efficient use of energy without reducing production levels, product quality or employee morale, and without compromising safety and environmental standards. It should not only address higher efficiency generation, energy conversion, distribution and utilization, but also explore lower-cost energy alternatives. Simply put, energy management is optimizing the energy cost per unit of product output. In this Chemical Processing Energy Efficiency eHandbook, we take a look at how to achieve effective energy management including: • Energy management programs – the roles and responsibilities needed to create an effective energy management program • Internal and external resources needed for an effective energy management program including what to expect from top management • Energy management basics – the five key activities to help reduce energy use • Compression dryers – a review of three alternatives: heat, desiccant and refrigerant. Understanding whether the purchase “cost” outweighs the “value” in terms of energy consumption and production levels.

  • CP eHandbook: Reliability/Asset Management

    Reliability programs are now standard business practice in companies that rely heavily on machines, equipment and other physical assets. But, in today’s lean economy, companies have fewer resources than ever to manage and maintain these assets. Plants face challenges in identifying new and cost-effective ways to ensure their assets are performing and that they are managing to minimize operational risks. In this Chemical Processing Reliability/Asset Management eHandbook we take a look at proactive approaches for improving reliability and maintenance in today’s processing plant including:
     

    •    Equipment rotation: identify damaged and worn components before they cause problems

  • CP eHandbook: Dealing With Water Challenges

    For chemical processors, the use of water in their processing can correlate to significant costs. Cost, coupled with an increasing focus on the environmental impact of both water usage and wastewater creation, are challenging processors to take a closer look at both their consumption of water and production of wastewater. Wide-ranging water optimization efforts, from fixing pipe leaks to minimizing cooling tower blowdown, are providing significant savings to chemical makers, but there’s more. In this ChemicalProcessing Water/Wastewate eHandbook we take a look at how to deal with water challenges including:

  • 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
