  • Process Filtration Scale-Up from Lab to Commercial Operation

    This article discusses process filtration approach developed for each technology stage starting from batch filtration in the lab to continuous filtration for the full-scale commercial operation. Process engineers must not “jump to conclusions”, a reference from Sherlock Holmes and Dr. John Watson who prove time and again is that there is no benefit to jumping to conclusions. Therefore, laboratory / bench top filtration testing is covered for problem analysis, technology selection and pilot and demonstration scale-up. The paper continues with the filtration testing and then scale-up to the commercial size. Finally, the paper concludes with a general review of the problem-solving skills of Holmes and Watson and how these skills can be utilized by process engineers as a framework for “idea-generation” when analyzing a new process scale-up.

  • Process Filtration Technology: Making Informed Decisions

    Solid-liquid separation is an instrumental part of chemical processing. To separate the solid particles, filter media made of textile or metallic materials and of composite materials are used as the basis for the filter cake. Often there will also be a washing process to improve the purity of the filter cake or to increase the yield of the liquid phase. Solid-liquid separation can be carried out in continuous or batch operation. There are many factors for selecting the right process filtration system for your specific application. This white paper reviews methods for identifying the right process filtration technology for your application and highlights case studies illustrating the methods discussed.

  • Chemical Processing’s Flow eHandbook: Master Flow Challenges

    Issues related to physical properties, process parameters, electronic features and interconnections can all affect the flow of liquids and gases. Often working around the clock to process, transfer, and store sometimes hazardous and corrosive chemicals, processors must tackle issues related to physical properties and process parameters. In this Chemical Processing Flow eHandbook, we take a look at what it takes for chemical processors to master flow challenges for several types of materials with vastly different physical properties including:
    • How to increase process availability - coriolis mass flow meters provide reliable indication of gas entrainment
    • Overcoming the challenges of changing gas composition - new technology addresses need for more accurate and efficient biogas measuring
    • How to ensure proper control of parallel flow paths demands care
    • Case Study: Speed Pipe Installation - pipe-joining system eliminates need to weld or thread connections
    • More!

  • Optimizing the Mixing of Powders into Liquids – Dust-free Induction and Dispersion

    Mixing of powders into liquids should be relatively easy. You pour powder onto the liquid's surface and then mix it in. However, this mixing can be very troublesome in production. This paper examines the various factors involved with mixing powders into liquids and how to avoid potential problems.

  • 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.

  • What Does It Cost To Own Your Dust Collector Filters?

    When choosing filters for your cartridge dust collector, a Total Cost of Ownership (TCO) calculation allows you to make the most economical and sustainable choice. TCO is a step-by-step evaluation that explores energy use, maintenance and other factors to compare the real costs of operating a dust collector with different filters. This white paper explains how to perform TCO calculations to save money, time and energy.

  • Asking The Right Questions About Cartridge Dust Collection

    Over the past decade, cartridge-style dust collectors have overtaken baghouses as the preferred technology for dust collection in the chemical processing industry. Combining high efficiency filtration with compact size and reduced pressure drop, a high efficiency cartridge dust collector will in most cases be the system of choice.

    Choosing the best cartridge collection system for a given application, however, involves research and attention to detail. This article will review four key areas of investigation. By reviewing these topics with a knowledgeable equipment supplier and knowing the right questions to ask, chemical manufacturing professionals will be better equipped to make informed dust collection decisions.

  • Chemical Processing Special Report: Compressed Air

    Chemical manufacturers today are looking at all aspects of their business to conserve energy and decrease costs. Compressed air is often over looked in these efforts as many people do not fully understand compressed air equipment, their own system, or what it costs to produce compressed air power. In this Special Report, we review compressed air and provide insights on how to understand equipment and identify potential areas for savings.

  • Spray Gas Quench Design Considerations

    The use of spray nozzles to rapidly cool or quench gas streams is an essential application in many industrial processes, such as chemical reaction vessels, incineration, and power plant absorber gas inlet. An optimized spray quench design requires engineering analysis of the operating environment, spray nozzle performance and process reliability. This technical paper describes the design considerations for spray gas quench systems such as nozzle selection, process control, system configuration and reliability. Application of this knowledge can result in a gas quench system that operates efficiently and reliably with reduced vessel size, reduced atomization energy consumption, and minimized downtime, to achieve capital and operational cost savings for your process.

  • Design Considerations for High Liquid Rate Tray Applications

    Except for a few odd services, high liquid rate applications are typically the domain of either trays or random packings. Aside from the distributors, random packing designs are rather straightforward with the designer choosing the proper size to accommodate the fluid flow rates and achieve the desired efficiency. Trays, on the other hand, have a large variety of adjustable parameters and can be especially complex, especially when designed for high liquid rate applications.

  • Removing Liquid From Gas

    Liquid entrainment in a gas stream can be a disturbance in many industrial processes. In natural-gas processing, higher-order hydrocarbons, water or impurities have to be separated from the main methane stream. Upstream of gas compressors, droplets that can damage the impellers, have to be removed. With the recently acquired Knitmesh technology and the strategic alliance with Shell Global Solutions, Sulzer Chemtech can supply a broad portfolio of advanced, tailor-made systems for gas/liquid separation to customers in all industries.
