Pumps are among the most commonly used machines in the chemical process industries (CPI). Condition monitoring tests and predictive maintenance can help pump operators determine when to overhaul pumps in a way that minimizes costs. Despite pumps’ ubiquity and large energy demands, however, relatively little information is available on how to apply predictive maintenance approaches and condition...

Though times are changing, many of the traditional challenges associated with running a chemical processing plant remain the same. For years processors have been asking for leak-proof, high-performance valves, but it is only recently that valve manufacturers are employing new technologies, designs and materials that improve performance and reduce leaks.   Improved Cv values “Traditionally...

Sometimes the smallest parts — such as seals and gaskets — can have the greatest impact on plant performance. For this reason, seal and gasket manufacturers are developing innovative new materials and designs that will help these diminutive, but important, components stand up to the harsh operating conditions of the chemical process industries (CPI). “With multiple seals and gaskets...

There is a temptation that steam design engineers find difficult to resist — to put condensate from high-pressure (HP) steam mains directly into the low-pressure (LP), pumped condensate-return (CR) mains. After all, the CR main is so convenient — it is generally laid right next to the outgoing steam main in the same tunnel, trench or racks as the CR main returning to the steam plant. And, the...

Globe-style control valves are in virtually every chemical processing line where pressure and flow must be controlled. And for the most part, they perform as required, day in and day out, requiring little to no thought or attention. In short, control valves are not an everyday topic of discussion. In fact, the globe valve provides a direct contrast to today’s consumer electronics where major changes...
