Pen and Paper. Table and Chair. Bert and Ernie. These are example of the many items we often find together. These all provide some benefit when found alone. However, when we find them together, they are an unbeatable combination. The same should be thought of with AMS […]
Using instruments with Advanced Diagnostics is one of the three main strategies I commonly present to achieve process control and instrumentation reliability. There is a lot of diagnostic information available about your process that is not currently being captured. Accessing it allows you to fully develop a Predictive Maintenance (PdM) program for your process. […]
The biggest challenge plants have for process instrumentation is level measurement. Pressure, temperature and flow all seem to be addressed well but level continues to be a problem. This post is a reprise of previous posts, but given the number of challenges involving level, I think it worth another look. While differential pressure (DP) […]
One of the strategies I recommend to improve process reliability is the use of product tiers. Manufacturers of instruments have various tiers which should be applied with a specifically defined strategy. I have presented these tiers as premium, core and conventional. Premium tier products should be used in critical applications which are […]
Pump reliability is one of the biggest rotating equipment challenges in a process plant. There are literally hundreds of pumps to monitor and maintain. There are three strategies which can be implemented to improve punp reliability, which will be explored here. These are redundant/spare equipment, transmitters with advanced diagnostics and
Advanced diagnostics is the name given to a class of transmitters that provide additional information about the condition of itself and the process. In addition to internal electronics problems, advance diagnostics can alert you to power supply issues and condensation in the housing. Another feature is statistical process monitoring. Rather than just measuring […]
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 […]
A process mixer is one of the least understood pieces of rotating equipment in a process plant. There are literally hundreds of them from small portable mixers to large main reactor mixers. Because it is similar to a gear box, and lumped in with other rotating equipment, its performance is seldom questioned. […]
Pretty much every process plant has a boiler for the generation of steam. Steam is a commodity that is widely used around a process plant for many different applications. These include heating, steam jacketing, steam tracing, power generation (turbomachinery). In the case of high temperature applications, […]
