Compressed air is widely used throughout a process plant for automation and control. It can also be used for other process applications like injectors or Venturi tubes. Pneumatic devices such as air tools and cylinders is a third application for compressed air. With so many applications it often times does not get the priority it […]
Within a process plant there is all kinds of turbomachinery, including compressors, pumps and fans. They are generally steam driven and move a lot of fluid. They are large. They are expensive. The manufactures of turbomachinery will include basic controls to meet performance specification and safe operation. This presents a good opportunity to add […]
In order to reduce installation and operational costs, process plants have ofter used RTDs or thermocouples without a transmitter for temperature measurement. This is especially true for high density temperature measurements like distillation columns, reactors and bearings on rotating equipment. However, there are a number of disadvantages to this strategy and high density temperature transmitters […]
Historically, reliability was realized through Preventative Maintenance (PM). It was routine to replace components on a time schedule based on best practices at the time. This included bearings, seals and lubrication. However, it was realized that these compenents could be perfectly fine and did not need replacement. Predictive Maintenance (PdM) soon replaced PM schedules. With […]
Process creep is the term used to describe small changes within a process. Over time, however, these changes, while individually minor, can lead to significant changes from the original design. This can have a negative effect on your process equipment as it is now operating at a condition it was not designed to handle. Rotating […]
