  • How Automated Water Jetting Improves Tube Bundle Cleaning Efficiency

    Heat exchanger efficiency is a critical factor in processing productivity, and tube bundles must be kept clear of deposits to maintain that efficiency. Automated high-pressure water jetting systems, with flexible or rigid lances, remove deposits 75% to 90% faster than manual methods and are more operator-friendly.

  • Choosing the Right Emissions Control Option

    Determining the most economical option to control airborne emissions during chemical process operations presents several unique challenges. As with any add-on control system, the goal is to minimize the annualized total costs while maintaining proper operation. In this white paper, learn the different options that are available and which ones fit your process the best.

  • 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.

  • Benefits of State Based Control

    State Based Control is a plant automation control design based on the principle that all process facilities operate in recognized, definable Process States that represent a variety of normal and abnormal conditions of the process. State Based Control, implemented with the latest developments in object-based technologies, delivers direct benefits to its adopters in a variety of Operational Excellence categories. It results in productivity increases, higher asset utilization of both people and process, automated responses and recovery for abnormal conditions and provides an environment for knowledge capture directly into the control design.

  • Closed System Technology Drives the Trend Toward Safer, More Cost-Efficient Chemical Dispensing

    In dozens of industries and in millions of applications around the world, dangerous chemicals are transferred from their original shipping containers into smaller jugs or buckets or applied to other end-use processes. Historically, the predominant dispensing method in many of these applications has been through an open system where the liquid is poured out of the container. With a poured system, the container is often flipped on its side and the liquid is poured into a secondary container. The user then just carries the bucket to wherever it needs to go. A mental image of this technique quickly reveals its potential dangers and inefficiencies.

  • Successful Process Communications’ Best Kept Secret

    Sure, the process engineer is proud of his HMI (human machine interface) and the operations manager is pleased with his KPI (key performance indicators) dashboard and how effectively the system is running with the implementation of his new MES/MIS solution. The historian and analytic solution get all the credit when a field equipment crisis is averted. Does anyone ever think to thank the lowly driver? Without data, the HMI is just a pretty picture, and the best analytics in the world are only ideas without any basis in fact. Plus, tens or hundreds of thousand dollars are spent on that, while the driver budget isn't even a line item on the spec sheet. The communication arteries and veins reach out to all areas of the field equipment, sending and receiving data, efficiently and tirelessly ensuring the ability to acquire, analyze and adapt to the situations at hand.

  • 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.

  • Environmental Health and Safety Compliance in Biotech Companies: Common Deficiencies Encountered During Audits

    Environmental health and safety (EH&S) compliance programs for companies that house laboratories are complex and not easily maintained. Even the most basic plan involves keeping a variety of permits up-to-date, performing regular employee training, conducting inspections, complying with a myriad of chemical storage and handling requirements, and keeping a number of contingency plans current and complete. This white paper identifies the most common pitfalls and four simple steps to keeping your EH&S program current.

  • Managing Complex Equipment Status in a GMP Environment

    Batch manufacturing systems must maintain the status of equipment, including which are available, dirty, out of service, etc. In industries that enforce Good Manufacturing Practices (GMPs), additional status types and values for process equipment must be maintained. Rules associated with the equipment status can be complex and involve the equipment class, current equipment state and time in the current state. This paper covers the operator interface used to review the equipment status and the interlocking requirements between the recipe and batch phases based on multiple status types.
