  • Tackling Vacuum Challenges in Research and Production

    Often, due to compression dynamics in multi-staged vacuum-pressure systems there is a mismatch of capacities between the vacuum and compressor pumps (with vacuum pumps having a much larger nominal pumping speed than the compressors).

    In this first case study, find out how Busch was able to identify an operational solution utilizing different control instrumentation, as well as design considerations including recycle lines and safety features to enable simple vacuum and pressure operation seamlessly. In the second case study, find out how dry vacuum technology improves operational reliability and eliminates oil costs in phenolic resin production.

  • Dry Vacuum Solutions for Chemical and Pharmaceutical Applications

    Through the years many different vacuum technologies have been used to provide vacuum for chemical and pharmaceutical processes, including steam jet ejector, liquid ring, and rotary vane. Each of these technologies continue to have a place in chemical and pharmaceutical applications, but dry screw technology has become the technology of choice for most applications.

  • Liquid Ring Vacuum Technology for the Chemical Industry

    Vacuum technology never stops developing, and for decades it has continued to progress. However, despite many improvements, new developments and further advancements, one principle of vacuum generation that has remained to this day in certain applications – and still successfully applied – is the liquid ring vacuum pump.

  • Choosing the Right Technology for Chemical Processes

    Selecting the right vacuum technology for chemical and pharmaceutical processing applications is often difficult. A vacuum system must deliver the required pumping speed and ensure the required pump-down time. It cannot be sensitive to process gases and must meet all requirements. Reliability and economic efficiency also play a significant role.

  • eHandbook: Achieve Better Energy Efficiency

    Do you know how your equipment is operating? Have you done performance testing recently? If you have a general idea, be careful; generalizations can lead you astray. You must develop models for complex interacting systems and test your assumptions — and the generalizations! Then compare your various options and the capital required to the savings achieved. Use this to make an informed decision on how to proceed.

    To help achieve better energy efficiency, Chemical Processing has put together an eHandbook. It includes insight on:

    • Take a Closer Look at Equipment Performance -- Modern instrumentation packages reduce the need for testing — but not always
    • Cast Cold Eyes on Cooling System Interactions -- Take a look at the cooling tower, refrigeration compressor and condenser
    • Don’t Generalize Complex Systems -- Deviating from standard design temperatures requires careful evaluation
    • Consider Refrigeration Condenser Pressure -- Operating at design condenser pressure could wind up wasting energy

  • eHandbook: Effectively Manage Energy

    Higher energy efficiency ranks as a top priority in many chemical makers’ efforts to enhance sustainability and competitiveness. Are you challenged by energy efficiencies? Are you perplexed by planning the scope of your audit and investigation? Do you want to better understand how to develop an implementation plan to act on your findings?

    This Chemical Processing eHandbook takes a look at how chemicals manufacturers are meeting the energy efficiency challenge head on. Download this Chemical Processing eHandbook for insights and strategies including:

    • Plants Strike Down Energy Efficiencies: Large chemical manufacturers achieve improvements on many fronts
    • Break Energy Audits into Phases, Part I: A four-phase approach that cyclically repeats can yield improved energy savings
    • Break Energy Audits into Phases, Part II: After approval of projects, implementation can begin
    • More!

  • Guide to Vacuum System Design

    The phrase “Vacuum Cleaning System” refers not only to cleaning by means of vacuum hose and tools, but also to a multitude of tasks which can be accomplished by the same basic system components: a vacuum producer and separators. In this paper, we cover the vacuum cleaning system as a tool for good housekeeping. Such a system is generally designed to pick up and convey dry and free-flowing material that can enter and pass through the vacuum cleaning tool and hose. Further, the system is designed to allow for a selected number of operators.

  • Powder eHandbook: Combat Powder Processing Challenges

    In chemical production and processing, process design and process safety are crucial considerations – especially when powders are part of production and processing. Inherent challenges such as increasing throughput, accurately measuring powders to manage inventory and removing excess solvents are all challenges that chemical processors need to contend with. In this Chemical Processing Powder eHandbook, we take a look at these powder processing challenges and identify solutions and strategies to overcome them. Learn more about:

    • Vacuum conveying - customization, automation and safety
    • Matching level measurement system to a job - consider materials and work environment when choosing a device
    • Removing solvent vapors in diverse applications - dry and liquid ring vacuum pumps are alternatives to oil-sealed pumps
    • Meeting combustible dust compliance – how a facility tackles combustible dust with aportable central vacuum system

  • Case Study: Oil Eliminates Tar Buildup, Seizing in Vacuum Pump

    Value Proposition: Technical know-how and a lubricant recommendation from Dow Corning applications engineers helped drive costs down. Application: Lubrication of vacuum pump in chemicals rocessing plant. Problem: High-purity synthetic oil was rapidly oxidizing, resulting in a buildup of tar and varnish that caused pump seizure every four to seven days. Solution: New technology ultra high-purity synthetic blend vacuum pump oil
