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.
This white paper outlines trends and opportunities for gasket standardization in processing plants ... including the potential for more reliable sealing, cost savings, inventory reduction, easier installation and safety practices. Steps are outlined for achieving success in gasket standardization across steel, glass-lined and FRP piping.
This white paper discusses SONAR-based, clamp-on gas volume fraction meters which recently have been introduced to the industry that provide an accurate, real time, measurement of entrained gases. Coupling entrained gas volume fraction monitor with most types of process density meters, enables accurate determination of liquid and the liquid-solid components of aerated mixtures.
Designers who understand and can take advantage of the differences between fluid power and traditional electromechanical power can build machines that produce higher quality output with lower lifecycle costs. This white paper suggests that care must be taken, however, in selecting and sizing the hydraulic system elements and in tuning the motion controller for optimal performance.
Capacitance-type magnetic flowmeters have traditionally offered the advantage of having non-wetted electrodes and the ability to measure low conductivity fluids. However, they suffered from a sensitivity to flow noise and zero instability. Innovative technology overcomes these limitations and drives magnetic flowmeters into new areas of application, while reducing installed costs.
A bearing isolator is a non-contact, non-wearing, permanent bearing protection device. It has a rotor and a stator, and the two are unitized, so that they dont separate from one another while in use. Typically, the rotor turns with a rotating shaft, while the stator is pressed into a bearing housing. The two components interact to keep contamination out of the bearing enclosure and the lubricant in.
This eight-page PDF whitepaper discusses the importance of transmitter selection for centrifugal compressors. Appropriate selection is especially important in anti-surge and throughput control applications.
This 26-page white paper from Monitor Technologies discusses the difficulties in measuring bulk solids and powders in bins, silos and hoppers. Download this document to learn which technologies are out there that can make this job easier.
This 22-page paper from the Dept. of Energy, Hydraulic Institute and Europump explains the importance of understanding the total costs of ownership to achieve savings in energy, and operational and maintenance costs. It discusses what lifecycle cost is, what should be considered in a lifecycle cost analysis, and the role of proper pump system design.
The design of the expansion tank plays an important role in the successful operation of a heat transfer system using organic fluids. It can contribute to longer fluid life and lower maintenance. This paper describes the proper sizing, piping and valving, instrumenting, and inerting of the tank.
This paper describes how to select a transmitter based on best practices instead of the "surge-plus-10%" rule. It presents methodologies and tools to minimize unnecessary energy cost without increasing safety risk.
