Tandem seal option for the Dean RA Series air-cooled pump helps protect environmentally sensitive areas from ground leaks, increase safety with added protection to avoid flammable fluids and improve compliance with insurance requirements.
Compare and understand the most common calcium carbonate scale prediction methods for cooling waters. Learn where and why some methods are inaccurate, and understand how an accurate prediction method can optimize a calcium carbonate scale-control program as well as provide a cost reduction in cooling water treatments.
January 11, 2019
Predicting calcium carbonate scale in water systems has been done for more than 20 years — often with questionable or even inaccurate results rather than actual field observations.
When heat must be dissipated from a process fluid — either liquid or gas — it is usually transferred to another fluid — either liquid or gas — using a heat exchanger. The two most common types of heat exchangers are liquid-to-liquid and liquid-to-air.
Few perfect things are perfect in this world — though a baby’s smile, beachfront sunsets and a pitcher who retires 27 consecutive batters come to mind. Unfortunately, for those who operate industrial facilities, hot-water heating, process loops or closed-loop cooling-water recirculation systems are not among them.
The Fluid Controls Institute (FCI) updated American National Standards Institute standard ANSI/FCI 87-1, Classification and Operating Principles of Steam Traps. It now includes three important information sections.
Specifications for Calflo, Petro-Therm and Purity FG HTF heat transfer fluids, manufactured by Petro-Canada Lubricants Inc., have been added to aspenOne Engineering software. The companies expect the additions to the Aspen HYSYS and Aspen Plus modeling software to provide engineers with a range of solutions when designing a heat transfer system.
When it comes to heating and drying needs on construction sites, a fuel-efficient system can significantly affect operating costs. The major types of heating systems are direct-fired open flame, indirect air and circulating water (hydronic). Hydronic heaters offer good fuel efficiency and do so while minimizing fire risk.
